Dagny Taggart’s Ultimate Guide to GMAT Preparation GMAT Basics:

The Graduate Management Admissions Test is the standardized exam used by graduate business schools for admissions decisions. It is designed and produced by the Educational Testing Service (ETS) and administered through the Graduate Management Admissions Council (GMAC). The three-hour, computer-adaptive test is almost exclusively multiple-choice and yields four scores: Total, Verbal, Quantitative and Analytic Writing Assessment. What the GMAT Measures:

GMAC claims the GMAT can measure basic analytical, quantitative and reasoning abilities developed over time. However, according to the GMAC web site, the GMAT does not measure: “every discipline-related skill necessary for academic work, nor does it measure subjective factors important to academic and career success, such as motivation, creativity, and interpersonal skills.” It continues, “GMAT scores cannot be used to estimate potential for success in a career, because many factors other than basic verbal and mathematical abilities influence work performance.” Test Administration:

The GMAT switched to a computer adaptive testing (CAT) format in 1997. Since that time, multiple problems with cheating, computer system failure, and scoring errors have been identified. In 2000 ETS admitted that scores for 3% of all tests taken between February and March were miscalculated, but students were not notified until December. Common pencil-and-paper test-taking strategies cannot be used on computer delivered exams. Test-takers are unable to underline text, scratch out eliminated choices or work out math problems on screen. Studies also indicate that computer screens take longer to read than printed materials, and that it is more difficult to detect errors on computer screens. Taking the GMAT costs applicants $200 each but colleges pay nothing to receive scores. Since 1985, GMAT has increased fees by $170 per test but offers no financial assistance for test takers of limited financial means. GMAT Grading and Scoring:

The Verbal and Quantitative sections are each scored on a scale of 0- 60. A Total score is calculated by adding Verbal and Quantitative scores then converting this number to a 200-800 point scale. The Analytical Writing Assessment (AWA) is scored on a 1-6 scale. This section, in which students have an opportunity to display creative, innovative and concise writing skills, is graded by two “evaluators,” one of which is a computer. . Predictive Validity and Margin of Error:

GMAC has been able to validate the GMAT for just one purpose: predicting first-year graduate school grades. But GMAC concedes that the GMAT can predict less than 17% of the variation in these grades on average. Independent researchers put the percentage much lower at between 4% and 9%, meaning that over 90% of what determines how well a student will do in their first year in business school is not captured by the test. According to GMAC’s own studies, all graduate schools have access to a better predictor of success undergraduate GPA’s. GMAC’s validity studies use all four scores (Total, Verbal, Quantitative and Analytic Writing) to assess predictive validity. Many schools, however, do not consider Analytic Writing scores in making admissions and financial aid decisions, thereby lowering the test’s minimal added value. An ETS report concludes, “including the Analytical Writing score as part of an admissions screening battery would substantially increase the number of eligible women” because females score higher than males on this section of the GMAT. According to GMAC, two students’ scores have to differ by at least 41 points before they indicate a difference in the abilities measured by the GMAT which means that colleges cannot determine the better qualified of two students whose scores are 530 and 570. Admissions Cutoff Scores:

Due to the GMAT’s weak validity and lack of precision, the GMAC Code of Ethics states: Avoid the use of cutoff scores. scores . Cutoff scores should only be used when there is clear empirical evidence that a large proportion of the applicants scoring below the cutoff scores have substantial difficulty doing satisfactory graduate work. GMAC continues, “In addition, it is incumbent upon the school to demonstrate that the use of cutoff scores does not result in the systematic exclusion of members of either sex, any age or ethnic groups, or any other relevant groups in the face of other evidence that would indicate their competence or predict their success.” In addition, the National Association of Graduate Admissions Professionals’ handbook Professional Standards and Practices states, “It is advisable to consider implementation of additional practices that eliminate discrimination, provide equal access and treat tests as a

This website stores data such as single component of the admissions procedure since test scores are not the sole measure of potential success.” Despite this strong guidance, cookies to enable essential site hundreds of schools use absolute cutoff scores for admission and financial aid. For example, Texas Christian University has an accelerated MBA program that requires a 620 on the GMAT. Chapman College of Business and Concordia functionality, as well as marketing, University each demand a 500, while California State University at Stanlihaus mandates a 450. The University of North Florida is even personalization, and You more explicit: “aanalytics. minimum 20 verbal and 22 quantitative GMAT sub-score is required for graduate admission.” GMAC recognizes theseatabuses are widespread, noting among “Business School Application Tips” in one publication, “Minimum Score may change your settings any time Requirements: Some schools require minimum scores on the Graduate Management Admission GMAT. Other schools only have or accept the default settings. minimum requirements for certain sections of the GMAT. Know the minimum requirement at a particular school, if one exists, so you

only apply to schools you are qualified to attend.” GMAC takes no action against schools that misuse its test results. In fact, schools with cutoff scores are listed in GMAC’s college search and financial aid identification programs and given all of the benefits of GMAC membership.

GMAT ‘Merit’ Scholarships:

Marketing Millions of dollars in “merit” scholarships are based on GMAT cutoff scores. For example, the University of Oregon’s Lundquist College of Business Scholarship requires a 650 on the GMAT. Many aid programs consider only the GMAT “Total” score (Verbal + Quantitative), potentially decreasing the number of women by excluding Analytic Writing. Personalization The average cost to attend business school is a little over $10,000 per year. Top 25 schools however, cost more than double that, Analytics

  Rankings publicized by magazines such as U. S. News & World Report and Business Week contribute to the illusion that GMAT scores are a valid measure of the worth of graduate management programs and their students. The average GMAT scores of enrolled students count for almost one-sixth of a school’s total weight in both publications. Nearly a quarter of all MBA applicants say these rankings are  “extremely important” for deciding where to apply. Many business schools point to rising sc scores ores as evidence of higher standards, neglecting to put them in the context of the rapid climb of average GMAT scores — 57 points in the past 18 years. Women and the MBA:

Women graduate from college with higher undergraduate Grade Point Averages (GPAs) than men but score 38 points lower on the GMAT- - a gap that has grown by 28 points since 1982. Women who graduate from Business School have, on average, GPA’s equivalent to those of men. Independent research indicates that the GMAT over-predicts the performance of men and under-predicts that of women. Test scores play a role in school choice. Men are much more likely than women to send their GMAT reports to “Top 20” schools and define such a school as their top preference. Women submit fewer applications and apply to less selective schools than their male counterparts. The number of women in business schools peaked at 30% and remained flat for several years. GMAC reports that while 87% of MBA programs received more total applications for 2001-2002, less than half of these schools saw an increase in applications from women. Almost one-third of business schools at private universities have seen a drop in female applicants. African Americans and Latinos:

In 2000-2001 African Americans scored, on average, a verage, 111 points lower than Whites. Latino populations scored between 64 and 87 points lower than Whites. The huge score gap between Blacks and Whites has narrowed only slightly in two decades, while the difference between Latinos and Whites has widened. In 1994-1995 on ly 143 Blacks scored higher than 650 (over 100 points lower than the averages for top-tier schools). High-scoring Whites outnumbering high- scoring Blacks 75 to 1. Without affirmative action, African Americans and Hispanics would be much less likely to get into a top-25 graduate business school. Members of these groups enter the MBA pipeline with far more concerns regarding their abilities to meet academic and curriculum demands, fears reinforced by much lower GMAT scores. African Americans and Hispanics are greatly disadvantaged by a test with little predictive ability and multiple opportunities for abuse. Other Groups:

Applicants who speak English as a second language (ESL) are disadvantaged by the primarily multiple-choice nature of the GMAT and the fast pace at which items must be answered. ETS studies show that when these characteristics are not part of the test (as in the Analytic Writing section) the score gap between whites and ESL applicants is greatly reduced. GMAC admits that average scores decline for test-takers over the age of 31. There is also an inverse relationship rela tionship between GMAT scores and business experience. Studies conducted for GMAC show GMAT scores under-predict the performance of older students (particularly women) but demonstrate that business experience directly contributes to success in MBA programs.

Alternatives:

GMAC and ETS have long been the national gatekeepers for business school admissions. Soon there might be some competition. Researchers at the University of Michigan’s School of Business have developed alternative measures of managerial potential that they claim better predict success in both academic and practical endeavours. This new assessment approach, dubbed the “Rainbow Project,” also claims to produce far less racial and gender bias than the GMAT. In 1985 Harvard Business School (HBS) decided to eliminate the GMAT from their admissions process. John Lynch, the Admissions Director at the time, gave several compelling reasons. In a blind test, Harvard found that admissions decisions made with and without

The only changes made since 1954 have been the addition of the AWA, which is used only sporadically and the move to the Computer Adaptive Test, which came with multiple problems. Harvard also pledged to work closely with GMAC to cooperate “on ways to further change the test” to focus on intangible qualities.

Here's an interesting graph from Kellogg's 2004 entering class. This is a good GMAT question possibility. If 5282 applied to the 2-year MBA class resulting in 469, what percentage of students were admitted with the various GMAT brackets of scores as shown in the graph? When you do the math (Taking into account that Kellogg admits 12% more than needed for instances where the applicant chooses another school), you get the following: 640 or less GMAT = 1056 apps with 42 accepted at 4% acceptance. 650-690 GMAT = 1584 apps with 158 accepted at 10% acceptance. 700-740 GMAT = 2059 apps with 252 accepted at 12.2% acceptance. 750-780 GMAT = 581 apps with 74 accepted at 12. 7% acceptance. That means the 2004 class cla ss had 25% of all students who scored 700 or more accepted. However, the actual student population is actually 62% people who scored 700 or more. This is actually a great challenge and encouragement as I thought it was much worse. So 38% of the class scored 690 or less? That's cool. 700-740 is only 2% more likely to receive acceptance than those who had 650-690. Not much of a difference. I think this is why we ought not to kill ou rselves for not getting 700 and for not killing our self if we do get 700 or more and don't get into a top Business School. That 2% can't hurt though.

The graphic below is part of how student needs are assessed. Each red zone is a plateau. It is a score range that is REALLY hard to break through. You are in the plateau that the course is designed to get people to. Don't believe the nonsense out there. There is no super effective one-size-fits-all solution to maximum GMAT improvement. Achieving and moving through each plateau has its own unique set of needs and concerns.

Study tips

1.  Rec ord all mistakes on wrong questions and revisit them no sooner than 5 days. If still getting wrong, then zero on the subset's and go for more help.

2.  Always read the explanation in the book to see why you get it wrong and take enough time to really understand the concept.

  Interesting note: The Official Guide for GMAT contains questions that are in the 550 to 650 difficulty range.

Let’s Get Started 

Use a track sheet that will help you to zero in on on the what you can target for improvement. improvement. Instead of saying, I need to improve in math you’ll be able to say, “I need more work in probability, more work in stamina or more work in seeing various forms of misplaced modifiers in sentence correction questions. One thing is for sure, most people find that 50% or more of the reason why they get a question wrong is due to carelessness, or a loss/lack of stamina. Without a good tracking system, you may no nott be able to measurably know by how much this is true or whether it’s it’s something else. It’s also good to make the notes area fr frequently equently to note the kind of subcategories of question types or if it was a concept you didn’t know or a concept you did know, but weren’t solid on yet. When you start out, it’s helpful to spend spend a week or two un-timed. Then as you progress, start putting y yourself ourself under moderate time pressure to at least record how long it’s taking you to do a particular question. It would be completely ridiculous to record how long it took you to answer every question. It’s far better to track yourself yourself in blocks of time. For example, with 12 questions, you should have X minutes left and with 24 questions, you should have X minutes left and so on. Another excellent tracking method is to p put ut one, two or three X’s in the slow box if you took longer than real GMAT time conditions to answer the question. Another good strategy is to go through questions in the following manner. 1)  Do about 40 questions at a time. In this way, you sho should uld be giving yo yourself urself 80 or so minutes to complete them. them. This will help you to get used to doing questions in blocks similar to the GMAT. This will build your physical stamina and build longer periods of mental toughness and focus. 2)  Check your answers and DON’T look at the explanation of the answer. Circle the right answer in red and the sheet. 3)  Go back, and use the teaching method as explained explained earlier to resolve the problem. Note whether you find the reason why you got the answer wrong as careless or due to concept error in the chart. A concept error is defined as an error where you didn’t understand the theory enough to know which steps steps and in what order to solve the pro problem. blem. It could also be a relevant piece of knowledge that you forgot forgot or haven’t learned yet. See the sample posting above tto o get an idea of what a teaching method solution looks like. 4)  Next go through the explanations to try and understand if you your methods were right or if the book offers an alternative solution method. There is more than one way to explain or solve many problems, so don’t feel like you have tto o follow the particular explanation in the book. If your method solved it, and yo you u can repeat it, then stay with what you know as long as it it holds up to scrutiny when slight changes in the problem problem don’t allow your method to to work. In which case, you’ll need to adapt the book concept or dig deeper into asking yourself whether you really understood the concept to begin with. By the way. It’s really helpful to ask yourself two questions when you’re done with each test problem re-solve 1) would I be willing to bet $20 that I really understood the concept being being tested? 2) Did I write out my explanation well enough that most anyone could look at it and understand how I solved the problem?

Resolved) Question Format Process of Elimination

One of the most useful skills you can master for any standardized test is Process of Elimination (POE). For every question on the GMAT, there are five answers, but only one of them is deemed .best. by GMAC. (But ’best’ is rat her subjective, especially when it comes to GMAC and verbal questions.) Often the easiest way to identify the right answer is to find all the wrong answers and eliminate them. POE is very useful in verbal because often the best answer isn’t all that great. While the credited response might suck, there isn’t anything in it that makes it wrong. There’s nothing in it you can point to and say this is wrong .Focus your energy on getting rid of the answers that you know are wrong. We’ll go over the individual problems that wrong answers are most likely to have in the appropriate topics and lessons. And remember, use your erasable note board for POE. Since you can’t cross off the wrong answers on the screen, write ‘ABCDE’ on your note board and cross off choices as you eliminate them One of the keys to successful POE is to avoid creating stuff. A great many of the wrong answers in the verbal section, especially in critical reasoning, are tempting only if you work to connect the answer to the question.As soon as you start working to justify an answer choice, or start telling some story to connect an answer back to the question or the argument, you’re almost certainly dealing with a wrong answer. The right answer doesn’t need any help from you to be right; it is supported by the information in the passage or argument or question Ultimately, even the verbal part of the GMAT is objective. Objective? Well, maybe not exactly. But the fact is that there are definite reasons why every right answer is right and every wrong answer is wrong. The key to success on the verbal section of t he test is figuring out what rules GMAC uses to determine the right and wrong answers.  answers. 

Focus on why GMAC thinks answers are wrong, and the verbal section will w ill become a breeze. Identify Wrong Answers

An Approach to Solve Sentence correction

Look for a 2/3 Split in the answer choices.  Most of the time, two of the answers will try to correct the sentence in one way  way  and the other three will try to correct the sentence in another way. This ’2/3 Split’ is v ery useful in helping you determine what grammatical issue is being tested. •  Using the 2/3 Split and your assessment of the question, eliminate answers that fail to correct the error you found. •  Evaluate the remaining answer choices. •  Eliminate those that introduce secondary errors. •  Examine all the differences among the remaining answers and choose the best one. Here C is best

Look at the 2/3 split. Should we go with ’they’ or ’the codes’. They: Are you sure you know what ’they’ refers to?. The Codes : We must use ’the codes’ to eliminate the ambiguity with the word ’they. Which is the best answer between D and E? Look for secondary errors D : No. This answer changes the meaning of the original sentence by adding the language ’able to be’. E : Yes. This answer corrects the initial error and introduces no secondary mistakes. Just because a sentence ’sounds right’ does not mean that it is grammatically correct. Our ears are trained by everyday speech, and everyday speech is frequently grammatically wrong. GMAC knows many cases of sentences that sound right but are actually wrong, and they will utilize these special cases to trap you. Instead of using your ear, always try to apply a rule of grammar. Don’t forget that a sentence can be correct as written. Sometimes GMAC will use a sentence that ’doesn’t sound right’ but is actually correct. Notice that the wording of the sentence is somewhat stilted and formal. But can you find a grammatical error? When you can’t find an error, you should look at the 2/3 split for clues as to what issue might be being tested. In this case, which is correct: ’is’ or or  ’are’?

The subject will usually be a noun phrase (a noun and the words, such as adjectives, that modify it) followed by a verb. e.g.: David works hard. Who "works hard"? =David does=the subject. Beer and wine are my favourite drinks. What "are my favourite drinks"? Beer and wine are=the subjects. The subject(s) of a sentence will answer the questions, "who or what." Clause

It is a group of related words, but unlike a phrase, a clause has a subject and predicate. Dependent Clause

Dependent Clause is a sentence that cannot stand alone. e.g. : When I went to store... Independent Clause

A connecting word used at the beginning of an independent clause. e.g.: Jim studied in the Sweet Shop for his chemistry quiz; however, it was hard to concentrate because of the noise. Independent makers:- also, consequently, furthermore, however, moreover, nevertheless, and t herefore Dependent Marker

A dependent marker word is a word added to the beginning of an independent clause that makes it into a dependent clause. e.g.: When Jim studied in the Sweet Shop for his chemistry quiz, it was very noisy.

A phrase (modifier after comma) usually modifies the subject of the earlier phrase or the preceding noun, which ever is appropriate. Its a group of related words that have no subject-predicate combination and cannot stand alone as a sentence. Absolute Phrase

A participial phrase does not modifying the immediately preceding word: Refer 1000SC-663 Example: Some of the tenth-century stave churches of Norway are still standing, demonstrating that with sound design and maintenance, wooden buildings can last indefinitely. The first portion before the comma is the independent clause followed b by y the portion portion in blue, an absolute phrase. An absolute phrase does not modify any word in particular. It modifies the whole sentence that either precedes or follows

it. Therefore, is notsuch the churches which demonstrate anything. Instead, it is the fact that they are still standing which demonstrate X.

e.g.: Or, Either-or, Neither-nor For disjunctive phrases with the use of or, either-nor, or neither-nor, find the subject nearest to the verb and make that verb agree in

Save either or neither Accept Allin a sentence alone (without or/nor), they are not considered to be part of a disjunctive phrase. In When are



  such cases, they are considered singular and take only singular verbs. Conjunction

A conjunction is required to join to independent clauses. Conjunctions are connecting words at the beginning of an independent clause. Watch out for sentences that have no logical connectors between two independent clauses. These sentences are termed as run-on sentences because they involve two independent sentences connected by nothing more than a comma. It can be corrected by adding a coordinating conjunction. e.g. (run-on sentence): I need to relax, I have so many things to do. e.g. (Fixing run-on sentence): I need to relax but I have so many things to do. I saw two movies this weekend; both of them were good. (Joining two sentences with a semi-colon) I saw two movies this weekend, both of which were good. (Using a relative pronoun (aka subordinating conjunction) to join two sentences) I saw two movies this weekend, and both of them were good. (Using a coordinating conjunction to join two sentences) e.g.: Jim studied in the Sweet Shop for his chemistry quiz, but it was hard to concentrate because of the noise. and, but, for, or, nor, so, and yet.

When two clauses are connected by a Subordinating conjunction one cause has to be an Independent one. Adjectives and Adverbs

Many adverbs are formed by adding ..ly. to the adjective. An adjective can only modify nouns or pronouns. An adverb can modify verbs, adjectives, another adverb, preposition, or a phrase. e.g.: Real, Really. Nice, Nicely. Slow, Slowly. Incorrect: Schumacher is a real good driver. The adjective ‘good’ modifying driver can only be modified by an adverb ‘real’ is an adjective and so should not be used. Correct: Schumacher is a really good driver. The adverb ‘really’ now m odifies the adjective ‘good’ correctly. Colon & Semicolon

The colon is used to equate two parts of a sentence where the second part is dependent on the first part. It is used primarily to introduce a list, introduce a quotation or formal statement, or introduce a restatement or explanation. Usually examples are stated after colon The semicolon is used to connect two closely related statements. Both statements must be able to stand alone as independent sentences. Incorrect: Andrew and Lisa are inseparable; doing everything together. Correct: Andrew and Lisa are inseparable; they do everything together Colon: You should be able to insert the word namely after the colon. Incorrect: I love listening to: classical, rock, and pop music. (Incorrect) Correct: I love many kinds of music: [namely] classical, rock, and pop. Gerunds   Gerunds

Gerunds are words ending in ’ -ing -ing.’ Remember to treat them as if they were nouns. Use the word like to compare them and give them a possessive noun or pronoun such as my .

Rule 1: Pronouns

Privacy Policy

Pronouns must unambiguously refer to a specific noun and also must agree in number with that tha t noun. The relative pronouns (that, which, who, what, when, where) refer to the nearest antecedent noun.


Ignore context when trying to determine if a pronoun is unambiguous. Pronouns are words that are intended to substitute for more Personalization specific nouns. The rule on ambiguity is strictly construed, so a pronoun is considered ambiguous if there is any chance it could refer to more than one noun


Pronoun reference error- referring pronoun is not correctly placed. pla ced. For example:

In the sentence “Samantha and Jane went shopping, but she couldn’t find anything she liked.”, the pronoun “she” does not refer to a Save unambiguously. Accept person It is All difficult to understand that whether “she” is referring to Samantha or Jane.



  The correct form would be “Samantha and Jane went shopping, but Samanatha couldn’t find anything she liked.” Subject Object Possessive

I Me My Mine You You Your, Yours He Him His She Her Her Hers It It Its We Us Ours They Them Theirs Who Whom Whose In this sentence, there is no way to tell for sure what w hat the word ’he’ is supposed to be referring to. This is called ambiguity. GMAC will correct a pronoun error in one of two ways: either by using a different pronoun that eliminates the ambiguity, or by eliminating the pronoun and using a specific noun. Which of these answers corrects the ambiguity? Answer (B) corrects the problem by substituting the pronoun ’they’ for ’he’. This eliminates any ambiguity because ’they’ refers to both John and Tim

Indefinite Pronouns

An indefinite pronoun is one that is not specific about the thing to which it refers (no clear referent) All pronouns that end in one, body or thing are indefinite pronouns. E.g. Everyone, Everybody, Everything Anyone, Anybody, Anything Someone, Somebody, Something No one, Nobody, Nothing The following are also indefinite: Whatever, whoever, Neither, Either, Each, Every. All the indefinite pronouns are singular. For each/every, if they precede a noun, the verb will take on a singular form as well. E.g. Each of the students is allowed to go on the field trip. Every dog and cat has paws. However, when each/every follow a subject, it has no bearing on the verb form. E.g. They each are good soccer players. There are however 5 indefinite pronouns that can singular or plural depending on the su bject. They are: Some, Any, None, All, Most E.g. Some of my marbles are missing (subject: marbles, verb: are). Most of the students are tired. None of my money is missing. Each, other/another, one

When two persons are referred in a sentence using each , other should be used. In case of three people the usage is each-another . When one one  is used to refer a noun only one  one can refer in that sentence. Eg. : One can achieve succeed in GMAT when one works hard. Relative pronouns are often used incorrectly today. 1) Referring Referring to things or animals – that, which 2) Referring Referring to people—who, whom They you’re positive there is a referring noun. Today we often use “they” 3) T hey – be careful that you don’t use this unless you’re

to replace the use of a proper proper noun which it is not. It’s a Pronoun. Which "Which" can be used as a restrictive or non-restrictive clause. It is a relative pronoun and should have an antecedent. In non restrictive

clauses It refers to the closest noun. Its always preceded by a comma. However, it does not always refer to the immediately preceding

noun. Sometimes, it, such much as like an absolute phrase does, will refer to the previous sentence as a whole.

Herethe ‘which’ obviously doesn’t refer to cedar, rather, it refers to ‘canoe’. The noun that the non restrictive clause modifies doesn’t necessarily need to be immediately proceed the comma.

Eg.: "The earth is not flat, which had puzzled many people in the old days." is wrong

Who/ Whom


You can tell when ‘who’ is more appropriate, and when ‘whom’ is more appropriate by changing the adjective clause into a free running sentence. If the free running sentence contains he, she or they, use who w ho Personalization e.g.: He had none of the appearance of a man who sailed before the mast. (He sailed before the mast)


If the free running sentence contains him, her or them, use whom e.g.: A man stepped in on whom I had never set my eyes before. (I have never set my eyes on him before) Save Accept All e.g.: Who are you going to marry? I am going to marry he/she.. (Wrong)



  Whom are you going to marry? I am going to marry him/her.. (Correct) Whose

Whose relates to people or to things. You can tell when to use ‘whose’ by changing the adjective clause into a free-running sentence. If the free running sentence contains his, hers, its, theirs, use whose e.g.: I am walking beside my father whose name is Simon Dedalus. (His name is Simon Dedalus) Where 

 ‘Where’ is generally used to indicate a place. When

 ‘When’ is generally used to indicate time. That

 ‘That’ modifies the nouns. It refers to to the immediate previous noun in the previous clause. It is a restrictive clause and provides essential information about the subject of a sentence. e.g.: The big GMAT book that is kept on the table is good. Note: No comma is used! "that" here refers to "the particular (definite/fixed) book on the table" That can refer to singular or plural. e.g.: In good years, the patchwork of green fields that surround the San Joaquin Valley town bustles with farm workers, many of them in the area just for the season. In the above example, what that refers to depends on the verb that follows it. If the sentence reads, ’a patchwork of green fields that ‘surround’. Here, ’that’ refers to ’green fields’. If the sentence reads, ’a patchwork of green fields that surrounds’. Here, ’that’ refers to ’patchwork’. Possessive Noun & Pronoun Reference

GMAT frequently tests pronoun reference in convoluted sentences in which pronoun is referred to possessive form of noun. The pronoun should have logical noun reference. e.g.: The department of labour allows the investment officers’ fees to be based on the performance of the funds they manage’. In the sentence above, ‘they’ can’t refer to ‘officers’. ‘Officers’ is used as a possessive noun to modify ‘fees’. Whereas, in the sentence below, ‘they’ refers to ‘officers’, ’The department of labour allows the fees of investment officers to be based on the performance of the funds they manage" Rule 2:-Misplaced Modifier (modifiers must stay close to home)

Sentences that begin with a verb, adjective+verb, and adjective phrases need to be followed by the noun or pronoun they are modifying. Usually end with –ing. Example: “Coming out of the department store, John’s wallet was stolen.”  “Coming” is the modifier. Was john’s wallet coming out of the s store? tore?  Incorrect  John’s wallet was stolen when he was coming out of the store. Possible solution to look for: i)  Correct the reference ii)  Put a noun or pronoun into the 1st part of the sentence turning the 1st part into an adverbial clause. Thus can stand apart without needing to watch the modifier.

A modifier, or modifying phrase, describes someone or something in the sentence. Modifiers are usually (not always) set off from the This website stores data such as rest of the sentence by commas.

Analytics this rule about misplaced modifiers: Phrases that modify or describe Remember other parts of a sentence must be placed directly next to the part of the sentence that they modify. Some types of misplaced modifier problems underline the introductory phrase instead of the second part of the sentence, as in this Save Accept All example.



  Since you cannot move the modified part of the sentence closer to the modifier (because modified part, cocaine derivatives, is not underlined), you must select an answer that changes the modifier so that it no longer violates the misplaced modifier rule. (A), (B), and (C) all repeat the original misplaced modifier error. Notice that (D) and (E) both correct the original error by re-wording the modifying phrase into a clause. The choice between (D) and (E) is tough.(E) is the correct answer. (D) is wrong because ’they were selling them’ contains a pronoun reference error. ’The government, a singular noun, ’ cannot be a ’they’.


You can change a misplaced modifier into a legal sentence by changing a phrase into a clause. “While leaving the bank, Evelyn’s purse was stolen.” (Incorrect, underlined portion is a  phrase) “As she was leaving the bank, Evelyn’s purse was stolen.” (Correct, underlined portion is a clause) Adverbial Modifier

When the word being modified is not a noun, the modifying phrase is called an adverbial phrase and does not need to touch the word being modified. e.g.: The running back ran towards the end zone, faster and harder than he had ever run before. The modifying phrase, faster and harder than he had ever run before modifies how the running back ran. Thus the phrase modifies  ‘ran’ and not ‘running back’. Modifiers with relative pronouns

Modifying phrases are often introduced by relative pronouns such as: which, that, where, who, whose, whom. On the GMAT, it is sometimes preferable to insert a modifier using a relative pronoun and a simple verb tense than using just an .-ing. form of a verb. e.g.: We test-drove a car having engine trouble (Awkward and not preferable) We test-drove a car that had engine trouble. (Relative Pronoun + Simple Verb Tense) Essential vs. Non-Essential Modifier

 ‘Which’  is  is used to introduce non-essential modifiers. These are clauses that provide information about a noun that is not necessary for identifying that noun. ‘Tha’ . is used to introduce essential modifiers. These are clauses that provide information about a noun that is nece ssary for identifying that noun. e.g. (Non-Essential): To find my house, walk down the left side of the road until you reach the third house, which is red. The sentence above always leads you to the third house on the left side of the road, and a nd this house happens to be red. e.g. (Essential): To find my house, walk down the left side of the road until you reach the third house that is red. The sentence above leads you to the third red house on the left side of the road.This may be the third house on the left side of the road, or it may be the tenth house on the left side of the road. That Vs Which

Most often than not, in GMAT, which would be preceded by a comma in the sentence. e.g. Get me the book, which is mine. Which is used to qualify the book i.e. which is mine. There may be many books in the room, but I want my book.  ‘Which’ should always refer to a noun. E.g. Get me the book, which is mine. So, ‘which’ here refers to the no noun un ‘book’.

  An Example Both of these sentences are correct in GMAT land: •  Please go into the room and get me the big book, which is mine. •  Please go into the room and get me the big book that is mine. Yes, in GMAT land, these two sentences have two different meanings. Both of the following sentences would be incorrect in GMAT land: •  X Please go into the room and get me the big book which is mine. X •  X Please go into the room and get me the big book, that is mine. X Notice the commas--that's what makes all the difference. The Explanation 

Okay, we have in English this weird idea that we need to use different grammar in an adjective clause (a.k.a. relative clause) depending on whether the information in the adjective clause is necessary to specifically identify which noun we are referring to. For example, imagine you have one sister, and you are telling a friend that your sister is coming to visit you. Since this person is your friend, we can presume that he knows that you have only one sister. You utter a sentence like this to your friend in GMAT land: •  "My sister, who just graduated from college, is coming to see me." In GMAT land, since your friend (we presume) knows you well and knows that you have only one sister, this extra bit of information is considered unnecessary to identify which sister it is you are talking about. It is a sort of "by the way" information--"My sister is coming to see me, and oh, by the way, she just graduated from college." Now imagine you have two, three, or even more sisters. Let's imagine that one is a college professor, another is a webmaster, and this one who is coming to visit you just graduated from college. If you're talking to your friend, and you say only "my sister," and you do not mention her name, your friend might not know which sister you are talking about. So you add that extra bit of information--my sister who just graduated from college--to identify which sister it is you are referring to. In this situation, we have just correctly employed a very important grammar rule. So, if the person you're talking to, or the person who's reading what you've written, needs that extra bit of information to know which noun you're referring to, we say that that extra information is non-restrictive. This word doesn't really describe the function clearly; so many teachers say that this information is "extra." On the other hand, if you need that information to know which noun you are talking about, we say that the information is restrictive.  Again, this word is not really a good choice for clarity, and many teachers use the term "necessary information" instead. Finally, just to make English a bit more difficult, there is a rule that says that we should use a comma before or after ‘extra information clauses and phrases’, but not with ‘necessary information clauses or phrases’. phrases’. The idea here is that the comma represents the slight pause in speech or change in intonation that a native speaker might use when making such an utterance. Both that  and  and which are relative pronouns, i.e., they are grammatically the same, but their meanings are slightly different. Now, let's return to our original example sentences: Please go into the room and get me the big book, which is mine. In this sentence, the clause which is mine is "extra" because the information "the big book" is enough to identify which book it is that you want. We can assume that there is only one big book in the room. •  Please go into the room and get me the big book that is mine. In this sentence, the clause that is mine is "necessary" because the information "the big book" is NOT enough to identify which book it is that you want--it is probably the case that there are several big books in the room, so I need to add the information "that is mine" to identify which book it is that I want. More Examples • 


I met with Bill Clinton, who is a lawyer. The name Bill Clinton is enough to identify which person I'm talking about-- who is a lawyer  is  is therefore extra information. I met with the man who is a l awyer. In this case, ‘the man’ is not enough information to identify which person I'm talking about-- who is a lawyer   is is

  (E) which any person could visit if they so desired The whole point of GMAT sentence correction is that we must choose the best answer, NOT the perfect answer. A modifier introduced by ‘which’ can be removed from the sentence without the sentence losing any essential meaning. Whereas a modifier introduced by ‘that’ is essential to the meaning. Commas are used to separate non-essential modifiers from the noun that is modified. The pronoun ‘who’ can be used in either essential or non-essential modifiers. e.g. (Essential): Only guests who are accompanied by tenants may use the gym facilities. The sentence above identifies a subgroup of guest to whom the pool is open: those accompanied by tenants. e.g. (Non-Essential): Only guests, who are accompanied by tenants, may use the gym facilities. The sentence above indicates that only guests (as opposed to tenants) may use the gym facilit ies and that they just happen to be accompanied by tenants. Exercise Identify the Correct Modifiers

Look for an item in the list that is not underlined to determine the proper form. Second, Second, items being compared must be of similar type. Apples must be compared to apples and oranges to oranges. Often, this means that nouns must be compared to nouns and action words to action words here are two common errors that come into play when making sure one part of a sentence is parallel to, or in balance with, the other parts. Lists The Rule:  Rule: All items in a list must be treated similarly. In this example, the list consists of ’to work, play, and to go’ . The items in the list are not treated the same Examine the answers.

In which answer are all the items treated similarly? In answer (B), all the items in the list are treated the same. Note that if the sentence had read, ’Floyd wanted to work, to play, and to go to the store’ , this would also be grammatically correct.  Lists are not always easy to spot. Make sure to take the time to identify all the elements in a list. Sometimes you have to read a sentence in a different way to correctly identify all the elements. items in the list must be parallel and there must be an "and" before the last item. If the list does contain "and" , it’s incomplete hence wrong. If the list contains more than one "and", then it’s a trapped list. However there can be multiple ands when items are different.

Personalization e.g.: Some bat caves take on different duties such as defending the entrance, acting as sentinels and sounding a warning at the approach of danger, and scouting outside the cave

Analytics Pronouns

Often, pronouns such as .which., .that., .those., .who., etc. - signal parallel structures. If one item includes a pronoun, it is often appropriate to include the same pronoun in parallel items. SaveI prefer to hireAccept All who work hard to those who don’t. e.g.: employees

All not list



  I enjoy going out with people who are humorous than those who aren’t. Exceptions in Parallelism

However there are some exceptions in parallelism which should not be confused with parallelism. Two gerunds + noun constructing is valid. e.g.: He liked sailing, swimming and girls. Verb + Gerund

e.g.: Some bat caves act as sentinels, sounding a warning at the approach of danger, and scout outside the cave Split Infinitive

The infinitive is the ’to’ form of a verb. When a verb takes the form to + the verb, it is called the infinitive form. Avoid sentences that insert a word between to and the verb. This error is called a split infinitive and is often incorrect. Don’t split it. Don’t put anything between ’ to to’ and the verb e.g. Correct: I need you to run quickly to the store. Wrong: I need you to quickly run to the store. Wrong : I cycled down to beach and swimmed. Correct: I cycled down to beach to swim. There are two kinds of ERS sentences that test the parallel construction. The first is first is a sentence that contains a list, or has a series of actions set off from one another by commas. The second kind second kind is a sentence that’s divided into two parts. Both types must have parallel types of verbiage:   …..to eat, to sleep ate _____, slept ____, drank ____.   Bad construction might look like: …to eat, sleep   …ate _____, sleep _____, drank ____.  

There are a few more things to be observed in a parallel construction sentence. Comparisons must be logical and compatible

Find the two things being compared and see if the sentence is structured in balance. Don’t be afraid to consider changing verbs or adjectives to get the balance. The words "like," "unlike," "similar to," "as…so", “when” and "in contrast to" are the most common indicators of comparisons. In comparisons, compatibility is determined by subject matter . For example:  “As domesticated animals, indoor cats typically lose their ability to hunt for their own food, so too do domesticated dogs c come ome to rely exclusively on their owners for sustenance.” Here, domesticated cats are compared to domesticated dogs, and the comparison works because they are both domesticated animals — they are like terms. Whenever you see a comparison being set up in a sentence, check to see that the terms of the comparison are compatible. Parallelism is not just about clauses, but verb usage

Example: -ing and –ing, to…… tto…… o…… , either ….. or, neither ……. nor. In a series of two or more elements, what you do on #2 determine s what you do on 3+. In other words, everything after #2 must match #2: •  I like to swim, to run, and to dance. •  I like to swim, run, and dance. are okay. •  I like to swim, run, and to dance.

Personalization Rule 4: Verb Tense

Analytics On the GMAT, tense problems are often just a matter of parallel construction. In general, if a sentence starts out in one tense, it should probably remain in the same tense.

Save Accept of Alltense: You don’t need to memorize types. Just be familiar. Some major categories



  a.  b.  c.  d.  e.  f. 

Present tense  Simple Past  Present Perfect  Past Perfect  Future  Present Perfect 

g.  Past Perfect  h.  Present Progressive  i. 

Perfect Progressive 

example: He walks three miles a day. example: When he was younger, he walked three miles a day. example: He has walked. example: He had walked. example: He will walk. Describes action that began in the past but continues until the present. Key identifier – “has” “have”. Note: Sometimes used when deadline exists. Describes action that started and stopped in the past. Key identifier – ‘had’  Used as emphasis by the speaker that the action is happening this very minute. Key identifier – verb ‘to be’ + a verb with an-ing ending.  Occupies more than one moment in the past.In other words, ongoing for a period of time. Key identifier – “had been” 

One exception to this rule is a sentence that contains the past perfect (in which one action in the past happened before another action in the past). Examples:   He had ridden his motorcycle for two hours when it ran out of gas. The dinosaurs are extinct now, but they were once present on the earth i n large numbers.   Two events that have taken place, are taking place or will take place at the same time must have the same tense in the sentence. Passive verbs begin with the form of ‘to be’ (Example: to be, were, was) and end with a different verb in the past tense. Use the present perfect perfect (has or have) when an activity began in the past and continues uninterrupted to the present. Use past perfect (had) when an activity began in the past but is then interrupted by another action in the past. Some sentences will contain errors in their verb tense. Although there are many verb tenses in English language, GMAC has chosen to test only a few. Just remember that tense refers to time and always look for time clues in a sentence to let you know when something is supposed to have happened. Generally, if a sentence starts in a particular tense, it should stay in that tense. perfect  is used for actions that began in the past and continue to the present. The present perfect Use ‘has’ for singular subjects and ‘have’ for plural subjects. In each of these examples the implication is that the action is still continuing.


Future tenses are not used in ‘before’ clauses. Could is a modal expressing past (potential) ability. If something is assumed in the past the usage of .Could. is appropriate. It is used to refer to Future in the past. If it is ongoing, ‘c ould’  cannot  cannot be used. Past perfect  perfect is used for actions that start in the past and are interrupted by another action also occurring in the past. Use ‘ had’ for both singular and plural subjects. On the GMAT, the past perfect is only appropriate when a sentence makes clear that there was an interrupting action and that the original action is no longer occurring. Here, ’until it jammed’ makes clear that the copy machine is no longer working. Some Past Participle of Irregular Verbs

the request does in fact not want oranges or grapefruit, but rather some other kind of fruit that is similar to oranges or grapefruit. In normal English: In GMATLand, like means similar to, and such as means for example. Take a look at these examples: •  Can you buy me some fruit like oranges or grapefruit? In GMATLand, this sentence would mean that you do NOT want oranges or grapefruit; instead, you'd prefer some fruit similar to oranges and grapefruit. For example, you may want pomelo, lemons, or limes. Yes, I know this sounds a little crazy, but our goal is to understand what GMAT is looking for, not what is " correct" English. •  Can you buy me some fruit such as oranges or grapefruit? Yes, this is what we're supposed to say in GMATLand -- oranges and grapefruit are exam ples of the type of fruit we want.

Subjects and verbs must agree in number. Always identify the subject and verb of a sentence. Eliminate any intervening phrases that are designed to distract you. Watch out for words that sound plural and are really singular, or vice versa GMAC will place irrelevant text, usually in the form of a prepositional phrase, in between the subject and verb of a sentence in order to distract you from the correct answer. This is GMAC’s favourite trick in the Sentence Correction section, so for the last time, be sure to isolate the subject and verb from any intervening information when you consider whether they are in agreement Pre-Exercise

Has, has, staggers, go (Compound subjects, like ’Bob and his friends’ require plural verbs), is (Species is singular), pleads (’Each’ really means ’each one’, which is a singular subject.) Approach Identify the Subject and Verb.

The first step in subject/verb agreement problems is to identify the subject and verb in a sentence. What do you think are the subject and verb in this sample question? Anything that Separates the Two Two..’Each’ is the subject of this sentence and ’were’ is the verb. Notice that the intervening prepositional phrases ’of the men involved’ and ’in the extensive renovations’ are irrelevant to the subject and verb. So, take them out and read what is left of the sentence Agreement.. Now that you have the correct subject and verb, make sure that they Check for Agreement agree: singular subjects must have singular verbs, plural subjects must have plural verbs. Is ’each’ singular or plural? Does it go with ’was’ or ’were’? Split  ’Each’ is singular and should be paired with ’was’. ’Each was en gineers’ is incorrect, so (E) is the correct Look for the 2/3 Split ’Each’ answer Either/Neither  Either/Neither 

When two distinct words or phrases are joined by the correlatives either… or, neither… nor, not only…. but also, the number (singular or plural) of the word or phrase nearest to the verb determines the number of the verb. Example: Either his parents or he is bringing it (notice “is” is singular) This can be a confusing sentence because   parents is plural, but we pay attention to he which is the noun “he” tells us that we ne ed to keep “is” singular. Example: Either he or his parents are bringing it. it. Notice “parents” is plural and is the closest to the verb so we use “are”   which is plural. ’Either’ and ’Neither’ both are singular when used as the subject of a sentence. For example: Neither  Neither of the boys has been arrested before.

  For example: Janie, with her poodle limping behind her, walks to the dog park. Explanation: Janie is singular. The poodle is singular. singular. They both are doing the action together, but the use of “with” means that we need to keep the verb singular. “Walks” is singular and “Walk” is plural. Remember, a verb that ends with an –s is singular. Definite/ Indefinite articles

English has two types of articles: definite (the) and indefinite (a, an.) The use of these articles depends mainly on whether you are referring to any member of a group, or to a specific member of a group. Indefinite Articles: A Articles: A and AN signal that the noun modified is indefinite, referring to any member of a group. These i ndefinite articles are used with singular nouns when the noun is general. Article: A definite article is used before singular and plural nouns when the noun is particular or specific. The signals Definite Article: A that the noun is definite, that it refers to a particular member of a group. None vs. All None is one of the indefinite pronouns that is singular or plural. There used to be a old rule that defined that none is less than zero so mostly, it inherits a singular verb.

e.g.: e.g.: All is e.g.:

In this question I think none  none of the answers are  are correct None None  of my friends is is  coming to dinner tonight. always plural . all of my friends are all  are  coming to the party

Singular noun + of + plural noun

When "of" is preceded by a singular noun and followed by a plural one, the rule is to conjugate the following verb with the plural noun if the latter can perform the action conveyed. Otherwise, conjugate it with the singular noun preceding "of". E.g.: The swarm of flies was very dense. As you can see, the flies cannot be dense. However, the "swarm" "sw arm" is singular. Hence, "was" is singular. E.g.: He is one of the students who believe math is boring. In the above, since "students" can perform the action of believing, the verb is conjugated with the plural noun "students". This is an example similar to the original question. An exception applies in the case of "one of": E.g.: One of the students believes that math is boring. In the above, it is actually not an exception; it is about logic. Ask yourself: Do the students believe that math is boring? No. Only that one student believes so. Hence, "believes" should be third person singular. 10%, half , all, and most  most would refer to more than one thing if the object of the preposition is countable (with one possible exception that we will discuss further). Each of./ One of.that

A commonly tested GMAT concept is that of "each of/one of + plural noun". The verb that immediately follows will agree with the subject "each of/one of" if there is no relative pronoun following. E.g.: Each Each  of the witnesses was was  questioned by the police. E.g.: Each of the books reminds me of her.  Do not get bothered by it. "reminds" should still be singularly conjugated. One  of the people is... •  One Each  of the students is... Each •  Imagined a situation like this:

"majority" should be used with countable nouns only. The majority of the water is dirty. Is "unidiomatic," because "water" is a non-countable noun. Just in case, countable nouns can be counted (bottle, idea, person, brush, etc.); Non countable nouns cannot be counted (water, furniture, information, soap, luggage, etc.). There is, however, a lot of overlap between the two--beer, coke, coffee, material, love, etc. can all be either countable or noncountable, depending on the meaning, context, or level of formality. One of the most common questions is something like this: Do I say: "Most of the people is/are...?" "Most of the water is /are...?" With fractions, percentages and indefinite quantifiers, the verb agrees with the preceding noun or clause. With singular or non-count nouns or clauses, use a singular verb:   One third of this article is taken up with statistical analysis. All of the book seems relevant to this study.     Half of what he writes is undocumented.   About fifty percent of the job is routine.   All the information is current. RULE: quantifier + of + NOUN + verb

The NOUN NOUN  determines whether the verb is singular or plural. For example: Most of the people is/ are... because the quantifier "most" refers to "people," (a plural noun) so "most" is plu ral in this sentence. Most of the water is /are... because the quantifier "most" refers to "water," (a non-countable noun) so " most" is singular in this sentence. So, from these examples, you should notice that we are looking mainly at whether the object of the preposition is count or noncount because the quantifier will take on this property from the object of the preposition. In other words, in these sentences: Most  of the people are... Most "Most" becomes a count noun because "people" is a countable noun.

Many idiomatic expressions tested on the exam involve prepositions. There's no overarching grammatical rule that tells you which prepositions go with which verbs. Again, the rules are determined by usage, so you'll have to ‘listen’ to the expression and determine if the verb is followed by the correct preposition. Be on the lookout for commonly tested prepositions like ‘of’, ‘at’, ‘by’, ‘in’, ‘from’, ‘to’, and ‘for’. If you have difficulty determining whether a usage is correct, try testing out the idiom in a simpler version of the sentence. Example: Although he was considered as a leading proponent for the controversial new initiative, the professor nevertheless sought refuge from the media uproar.

The sentence above becomes: The professor was considered as a proponent. Does anything sound unusual? Could this sentence be worded differently? In fact, to be, not as, is the correct idiom:

  Another frequently tested grammatical error is unnecessary use of the passive voice. It's a good idea to become familiar with this type of error; it appears quite often in the answer choices of sentence correction questions. As a reminder, the passive voice is in use when the action of the sentence is performed on the subject. The active voice is in use when the subject itself performs the action. Example: Active: Allison (subject) went (action) to the store to buy a cake (object). Passive: The cake (subject) was bought (action) by Allison (object).

Some pairs of words, like fewer and less, are often used incorrectly because they're treated as synonyms. In fact, there is a solid rule that determines which one you should use, and the exam will test your ability to decide which is the correct option. The exam tests four such word pairs with particular frequency, so memorize the rules pertaining to them if you don't know them already. 1.  Fewer/Less  Which of the two following sentences is correct? 


The company company fired fired no no fewer less than fifty employees. The than fifty employees. The second sentence is correct. Why? Because you use less when you're talking about things you can't count (less pollution, less violence) but fewer when you're talking about things you can count (fewer pollutants, fewer violent acts).

2.  Number/Amount 

These words follow the same rule as less and fewer. Number is correct when you can count the thing being described (a number of cars, a number of people) and amount is correct when you cannot (amount of love, amount of pain). 3.  Among/Between 

Use between when only two options are available (between the red car and the blue car) and among when more than two options are available (among the five answer choices, among the many books). 4.  Compared to v/s. Compared with:  

To show comparison between unlike things, ‘compare to’ is used. To show comparison between like things,  ‘compare with’ is used.

Accept context and isAll not incorrect.

Rule 1: Compare to  to compares unlike things, whereas compare with with  compares like things.



  Rule 2: Compare to  to is used to stress the resemblance. Compare with  with can be used to show either similarity or difference but is usually used to stress the difference . There is a difference between compare to and compare with; the first is to liken one thing to another; the second is to note the resemblances and differences between two things. 5.  Each

This question tests one use of "each" which most of us ignore. The traditional traditiona l rule still holds true i.e. ‘the subject of a sentence beginning with each is grammatically singular".

But there is another rule which says that: When each follows a plural subject, the verb and subsequent pronouns remain in the plural :

e.g. the apartments each have their own private entrances (not has its own private entrance)    

Three cats each eat ... Three cats, each of which eats ...,

In 1, each is postpositive Adj, whereas in 2, it is distributive determiner. e.g. 

In fact, each is almost always singular, but there's at least one exception. So, A can be faulted for using a plural verb, broadcast , with a singular subject, each. Option A uses such as, which is used to give examples. All the other incorrect answer choices use words that mean something different from for example. The best answer, E, maintains the same meaning as A, and corrects the subject/verb agreement problem. Please note that one of the accepted meanings of as is for instance, and with this meaning, as is an adverb and can therefore be followed by parts of speech other than simply nouns. B is not only awkward, it also incorrectly uses if in the subordinate clause connected with can in the main clause. I think this is the part that is confusing , so let's flip the sentence around to see a bit more clearly that it's not correct to use if with can: If all of the three major networks broadcast the same statemen statement, t, television can be superficial.

So I'm guessing you already know that being in an answer choice is wrong more often than it is right. This is a good strategy to get you started, but to get over 700 on the GMAT, you really need to know some of the finer points of GMAT Sentence Correction that relate to the use of the word being. There are at least two different situations in which being is often the right answer.

Personalization Analytics Save

Here is the first example of when being is correct:  a. 

When the grammar requires it. it .

Many ideas can be expressed in more than one way. For example, I can say:

Accept All

I'm afraid of being late. late.  I'm afraid that I'll be late. late.  



  Each has its own emphasis, but the point is that these two structures exist. Whether we can express ideas in one or more structures is really related rela ted to the word used; in other words, it is idiomatic. But some idioms allow only one structure. For example: In addition to being one of the first restaurants to combine Mediterranean and American tastes, Chez Panisse in Berkeley is also one of the Bay Area's most established restaurants. The idiomatic structure in addition to does not have a counterpart that uses a subject and a verb, so our only option here is to use being, which is grammatically a noun, but is derived from a verb.

w i t h + NOUN + b e i n g + NOUN COMPLEMENT


The second example of when being is correct is shown in this example: There are many reasons to get an MBA, with increased career prospects being the most important for many MBA applicants. Technically this part here: with increased career prospects being the most important for many MBA applicants

is an absolute phrase, but I think it's also h elpful just to memorize the pattern: Framed by traitorous colleagues, Alfred Dreyfus was imprisoned for twelve years before there was exoneration and his freedom. (A) there was exoneration and his freedom (B) he was to be exonerated with freedom (C) exonerated and freed (D) being exoneration and his freedom (E) being freed, having been exonerated C is correct. The main thing here is that we do not have the best option available to us:  

before he was exonerated and freed The second best option would be:


before being exonerated and freed

7.  Because v/s. In That:  That:  When ETS puts ‘because’ and ‘in that’ in a sentence, more often than not, ‘in that’ would be correct. ‘In that qualifies’ the previous sentence, while ‘because’ is just used to show a simple causal relationship.

GMAT grammar rule mentioned here will have some exceptions, for the reason that we are discussing GMAT patterns here and not "English grammar rules". It is very difficult to give a pattern that applies in every case. I would say that generally speaking, your summary is good, but just to be sure, I want to restate: Use like when you want to focus on two nouns; Use as when you want to focus on two nouns doing two actions. Another little trick is that "just as" can replace "in the same way that..." Let's compare two very similar sentences that could cause confusion: My Siamese cat moved across the floor just like a lion stalking its prey. To me, this sentence stresses how two different cats are similar. T his is confusing because we have a noun, "lion" and a participle "stalking," which would seem to indicate that we should use "as," but it's just not so. In this sentence, do you think we're trying to say that  a lion stalks its prey. My Siamese cat moved across the floor in the way that

I don't think so... My Siamese cat moved across the floor just as  as a lion stalks its prey. how  the cat is moving. Furthermore, at some point, we are going to This one sounds bad because we are not explaining how run into some ambiguity--"as" does also mean "at the same time," and I also think that the sentence above does sound a bit like two things are happening at the same time.

Let's look at a better sentence: as  a lion stalking its prey moves. My Siamese cat moved across the floor just as This one sounds very good; it explains how my cat moved. Furthermore, it has the same meaning as: My Siamese cat moved across the floor in the way that  that a lion stalking its prey moves.

11.  Not/But vs. Rather than

The key here is to realize that not... but... is conjunction. We use conjunctions when we want to join things that are "linguistically equivalent." Help much? No, probably not. How about some examples? Pucci is not a d og  but a ca t .   Not Todd  but T a k a  a   will be studying with us today.   I not was s ad but h a ppy  to learn that Megumi was moving to Paris for a better job. 

  C) with child-care facilities included and for clustered suburban houses to include communal eating and social facilities D) that included child-care facilities and for clustered suburban houses with communal eating and social facilities E) to include child-care facilities and for clustered suburban houses with communal eating and social facilities included

First, we can eliminate all the answer choices that use with communal eating and social facilit ies included or any other structure that follows this pattern: preposition + noun + participle This pattern is almost always wrong on the GMAT, and is certainly wrong in this question. This eliminates C) and E). A) is ambiguous--is clustered suburban houses parallel with child-care facilities or with urban apartment houses? We need to repeat for to be sure that clustered suburban houses is parallel with urban apartment houses. Now we're left with B) and D). Now, the only difference between B and D is the infinitive to include, wh ich GMAT considers unidiomatic. That leaves us with D).

Few Important Points to remember:

1) (less preferred) being < since < because  2) As Such such = nominal equivalent to the foregoing clause.

Clause1 and as such, Clause2 = clause1, and as clause1, clause2. Caesarea was Herod’s city, founded as a Romanized counterweight to Hebraic Jerusalem, and as such such  it was regarded with loathing by the devout. The meaning of the above sentence is similar to the following: Because Caesarea was Herod’s city, founded as a Romanized counterweight to Hebraic Jerusalem, it was regarded with loathing by the devout.

3) Reduced Costs = Reduction IN costs (result of reduction)  ‘Reduction of’ is used when reducing by a certain amount. e.g. reduction of 20%.

Second, f or al l means d e s p i t e, Second, f e , and a lo lo n g w i t h means i n a ddi t i o n t o . I'm sure you'll agree that the meanings are different, right? For example: I haven't visited Bora Bora, and neither has Kerry [visited Bora Bora].In this case, I can omit visited Bora Bora because it already appears in the sentence. Let's look at another example: I haven't visited Bora Bora, and I probably never will visit Bora Bora. This is wrong, at least on the GMAT, since visited and visit are different.

What a tricky question! Both A and E are grammatically correct, but they have a very slight difference in meaning. For this question, we most likely want the meaning in A, not the meaning in E. And, whenever we have two options that are both grammatically correct, and the only difference is one of meaning, we MUST go with the original meaning. In other words, if A is grammatically correct, not wordy, redundant, awkward, etc., and another answer choice is also grammatically correct, not wordy, redundant, awkward, etc., we must go with A. But I'm sure you want to know the meaning difference and the rule, right? Okay, here you go: I know you won't like this, but with this meaning, we use "in." For example: I wantyou to know how from far you will gowe intalked helping me."helpful" + "in," right? Well, this is very similar--"helping me" is a process. In I think remember class that about

this sentence, I am wondering how long you would stay with me while you are helping me, how many different things you would do to help me. For example, would you break the law while you are helping me if you thought I would benefit? Would you ignore your friends and family while you are helping me? Again: During the process, how much would you do? (A) has a similar meaning in this sentence. Let's now look at the meaning of E. I want to know how far you will go to help me.

In this sentence, we are using the infinitive of purpose, which we use to express a goal. If I use this structure, I am wondering how much effort you would expend to help me. In other words, would you come to me at midnight? Would you travel 50 miles, 100 miles, 1,000 miles to help me? Would you spend all your time and money to come to help me? Would you give up your job, health, and family to help me? Again: How much would you do to be able to be in a situation to help me?? I know that these two are very, very close in meaning, but read what I've written very carefully, and be sure to post back with any further questions!

Personalization quote: Analytics The visiting doctors concluded that the present amalgam is probably as good as or better than, any other system that might be devised for the patients. This is correct. OneAccept of the answer Save All choices used 'might' instead of 'may'... what's the difference between m a y and m i g h t ?  In general, may has more of a concrete meaning, so should therefore be used more in statements of fact, whereas might is a bit less tangible, and tends to be used more in expressions of things that don't yet exist (hypothetical situations). Also, a bit more simply, since might is the past tense form of may , we use might more in the past tense.



  All that said, we often use them interchangeably in many constructions--there is a lot of overlap between may and might . STH (verb): give responsibility for. Thomas Edison is credited with inventing the light bulb. • credit SB with STH  • credit X to Y Y  (verb): give money or credit to. The bank credited $1 million to Trebla's account. • credit for  for (noun): money received for or in exchange for something. The customer received a $20 credit for the interruption in service.

So there are a few things you need to know here for GMAT Sentence Correction. First is this--you should know that GMAT likes to test you on "thinking words." T hese are words that indicate some sort of mental process, such as believe, belief, idea, theory, notion, concept , etc. Please note that both verbs and nouns can be considered "thinking words." GMAT typically likes to follow these words with that and a sentence. For example, on the GMAT it's better to say: • Lucise's belief that the Earth is flat was easily accepted. than to say  • Lucise's belief of the Earth being flat was easily accepted. It is okay to use ‘ of’ if we want to indicate only a noun. That's why, for example, we say theory of relativity . In this case, if we choose answer choices that use of instead of that , we seem to be talking more about theories of land mammals; we are not identifying the action of those land mammals. In other words, with the ‘ the  ‘that  mammals   that ’  ’,  we are leaving out what it is that the theory purports the mammals did. Crises is the plural of crisis Data is plural of datum

We generally use do to replace "regular" verbs, i.e., verbs that are not linking verbs, verbs that use modals, etc. For example:  M e g u m i s p e ak s J ap an es e be tt er th an I d o.   Look at the following examples for something (perhaps) new:  M e g u m i h as v i s i t e d m or e co u n t r i e s th an I h av e. We  M e gcan u m use i h ashave m oragain e s k i rbecause ts t h an have I d o. is an auxiliary verb here. Here, has is NOT an auxiliary verb, we cannot use the verb have in the second bit. Here's what you need to know: having + past participle is used to express actions that are finished finished  and to show that one thing comes after  after another. Furthermore, there is usually a "because relationship between the two. For example: Having eaten already, I turned down Megumi's invitation to dinner. This sentence is okay. But this next sentence is NOT okay, because the two things should be happening at the same time. Having been sick and having felt tired, Alan did not want to go to work. All the things in this sentence are happening at the same time, so we should NOT use the "having + past participle" construction here. And this sentence is incorrect because there's no "because relationship" between the two parts of the sentence: Having set, the Sun rose some hours later. The Sun will set and rise no matter what; w hat; setting doesn't cause rising, so we shouldn't use the "having + past participle" construction here.

The use is justified by analogy to similar uses of many other adverbs, as in Mercifully, the play was brief or Frankly, I have no use for your friend. And though this use of hopefully may have been a vogue word when it first gained currency back in the early 1960s, it has long since lost any hint of jargon or pretentiousness for the general reader. The wide acceptance of the usage reflects popular recognition of its usefulness; there is no precise substitute. Someone who says Hopefully, the treaty will be ratified Privacymakes Policy a hopeful prediction about the fate of the treaty, whereas someone who says I hope (or We hope or It is hoped) the treaty will be ratified expresses a bald statement about what is desired. Only the latter could be continued with a clause such as but it isn't likely.

The reason C is not the answer is that C changes the meaning. Look at these simplified sentences: • However much you complain, I will not change my m ind. This sentence means no matter how much you complain, I will not change my mind . Or, to put it in a more precise way, my resolve to stick to my decision will not wane even if the degree of your complaining increases. This meaning is quite specific. Now compare it to this sentence: • Although you complain, I will not change my mind. This sentence means even though you complain, I wil l not change my mind. So, even though the two meanings are quite close, they are in fact different, and between two grammatically correct and plausible sentences, we must go with the one that doesn't change the meaning of A.

  Reading Comprehension Study Strategy

General Strategies for Reading Comprehension, by Stephen Bolton

1.  Try to read the whole text of t he passage once, if possible. Many people think you should just skim the passage or read 1. the first lines of every paragraph, and not to read the passage. We believe this is an error: if you misunderstand the main idea of the passage, you will certainly get at least some of the questions wrong. Give the passage one good read, taking no more than 3 minutes to read all of the text. Do not read the passage more than once – that wastes too much time. If you have not understood it completely, try to answer the questions anyway. Note: this point of reading the whole passage is important for test-takers whose first language is not English, provided that they can read the passage in 3 minutes or less.

2. Make brief notes on the text on your scrap paper.  As we will see below in greater detail, you should write down a couple of words on A) the Main Idea or Primary Purpose, B) Organization/Structure of the passage, and C) the Tone or Attitude of the author (if applicable). You just need a few words for each of these areas, and altogether it should not take longer than 30 seconds to write down.

3. Remember that the tone or attitude of the passage is usually respectful and moderate, never going to extremes of praise nor criticism. ETS obtains its Reading Comprehension passages from real articles about real academics and

professionals. So the tone of the articles, even when there is criticism in the passage toward an academic a cademic or her work, is always balanced and moderate. In the same vein, articles that deal dea l with minorities or ethnic groups are almost always positive and sympathetic.

4. Look out for structural words that t ell you the important ideas or transitions in a passage.  Continue the Idea Words 

Similarly Moreover Additionally In the same way Likewise Conclusion Words

5. Go back to the text of the passage for the answers. Many test-takers fail to return to the text of the passage to look for the correct answers. They rely solely on their memories and understanding of the passage after having read or skimmed it. Wrong. ETS is counting Accept All on that. Go back to the text to look for information to answer the questions. Nine times out of ten, the answer lies within the passage.

Of the 6 most important types of questions for Reading Comprehension, we will first look at Main Idea/Primary



  Purpose Questions, and the strategies we can use to answer them. Main Idea/Primary Purpose Questions

Many people believe there is no difference between the main or central idea of the passage and the primary purpose of the author of the passage. This is simply not true. Let's take a look at the subtle but important difference between them: Main Idea 

The question might look something like this: ’ Which of the following best states the central idea of the passage?’ ’Which of the following most accurately states the main idea of the passage? ’Which of the following is the principal topic of the passage?’ ’The main topic of the passage is....’ Primary Purpose 

The question might look like this: "The primary purpose of this passage is to..." "The primary purpose of the passage as a whole is to..." "The primary focus of this passage is on which of the following?" "The main concern of the passage is to..." "In the passage, the author is primarily interested in...." "The passage is chiefly concerned with..." Strategy:  Main Idea: Look in the first and last paragraphs for the main idea. Any conclusion words like therefore, thus, so, hence, etc. that you see are most likely introducing the main idea. The correct answer will say the same

thing as it says in the text, but using different words. The Main Idea is not always stated explicitly in the passage – in fact, more likely than not, it is not stated explicitly. Therefore, in order to answer this type of question when it is more implicit: 1. Re-read the first line of every passage, passage, and the last line of the first and last paragraphs. This should give you general structure outlinestructure of the argument, with which you can eliminate answer the Main Idea question. 2. the After determining theor general or content of the argument, answer choices that are too broad or too specific, i.e. answer choices that go beyond the content of the passage, or that deal with content only discussed in one paragraph of the passage. 3. Make brief notes – a couple of words- regarding the Main Idea on the text on your scrap paper while you read. Primary Purpose: What is the author trying to do? What is his intention? If he is evaluating a theory, then the answer could be something like "Discuss an interpretation". Note that the correct answer would deal with " an interpretation", because the author is only dealing with one theory. If the Primary Purpose is to criticize 2 new books, then his intention or his primary purpose might be to "Critique new studies". Again, as in Main Idea questions, re-read the first line of every passage, and the last line of the first  and  and last  paragraphs.  paragraphs. This should give you the general structure or outline of the argument, with which you can answer the Primary Purpose question. Note: A good main idea or primary purpose does not go beyond the scope of the passage, nor does it limit itself to discussing only one part of the passage.

What is the primary purpose of this passage? A) discuss the importance of the television program Star Trek for the international space program B) discuss important theoretical work concerned with faster-than-light space travel. C)dataexplore a dispute among theoretical physicists regarding the uses of space flight stores such as

You personalization, and This is a Primary Purpose question, so we have to determine what the author is trying to do or say in this passage. So, let's read the may change your settings at any time first and last lines of the passage in order to get an idea of the primary purpose. The first line says "Great news for Star Trek fans: or accept default warpthe drives that settings. can propel starships around the Galaxy faster than the speed of light may be possible after all--with all--w ith a little help from Dr Who." The last line is a quote by a physicist that says "Of course, there are still some basic questions--like how does one go about constructing this Tardis space-time--but it puts the concept of space warps back on the agenda." From both these sentences, we get the idea of space travel, faster than light travel and space warps – maybe this is a discussion of faster than light space travel. Does Privacythat Policy match what you have already read? Yes, basically this is a discussion of the theoretical state of play in the area of faster-than-light space travel. Do any of the 5 answer choices match that? Yes – B, even if the wording is somewhat different from how we are wording it, the idea is almost exactly the same. B is the answer. Marketing Another way of getting to the answer is through elimination of obviously incorrect answer choices. We can eliminate A because the author mentions the popular science fiction program Star Trek merely to introduce the idea of faster-than-light travel, and nothing Personalization more. C is a stronger possibility because the second paragraph of the passage does discuss some disagreement among physicists about the possibility of creating a warp-drive, but in the same paragraph the theoretical dilemma seems resolved. Moreover, since the Analytics author only discusses this in one paragraph, it cannot be the primary purpose of the entire passage. We can e liminate D because the author does not go into detail discussing the uses of space-warping material. And we can discard E because the author does not really go into how the space-warping Save Accept Allbubble would work in the real world. Title Questions 

Title questions are very similar to Main Idea questions, though are less common. Though some of the example passage we use in this



  tutorial and in the Practice Section are from the New Scientist, and therefore have titles, the passages in the real GMAT will not have titles. The question might look like this: "Which of the following titles best summarizes the passage as a whole?" Strategy

Treat this as a Main Idea question. A good title sums up the central idea of a passage. Therefore, in order to answer this type of question: 1. Look in the first and last paragraphs for the main idea. Any conclusion words like therefore, thus, so, hence, e tc. that you see are most likely introducing the Main Idea/Title. The correct answer will say the same thing as it says in the text, but using different words. 2. Re-read the first line of every passage, and the last line of the first and last paragraphs. This should give you the general structure or outline of the argument, with which you can answer the Title question. 3. Make brief notes – a couple of words- regarding the Title on the text on your scrap paper while you read. 4. After determining the general structure or content of the argument, eliminate answer choices that are too broad or too specific, i.e. answer choices that go beyond the content of the passage, or that deal with content only discussed in one paragraph of the passage.

What would be an appropriate title for this passage? A)

Constructing The Tardis


How To Make Space-Warping Material


Bubbles In Space-Time


Faster-Than-Light Travel: A Possibility?


Debate On The Uses of Space Travel


This passage actually already has a title, "Warp Factor One". But we have to look for another title possibility, one that would be most like the Main Idea of the passage. We look at the first and last la st paragraphs, and since the Main Idea is that researchers now feel that faster-than-light travel maybe more than mere fantasy, we can find the correct answer choice. Does any answer choice correspond to this idea? Yes- answer D, which is the correct answer. We can also find the correct answer through elimination. There is nowhere in the passage where it discusses building Dr. Who's Tardis (pity!), so we can eliminate A. Nor does it tell us how to make space-warping material. Eliminate B. While bubbles in space-time are discussed at some length in one of the paragraphs, we cannot say this is the main concern of the passage, and thus should eliminate C. And nowhere are the uses of space travel discussed, so discard E. Specific Detail or Target questions are probably the most common types of questions, and the easiest to answer. The question might look like this: "According to the passage,...."

This website stores data such as...."

Save Accept Allquestion, and therefore we look for the Name, Line Number, or Date that will help us. In this case, the This is a Specific Detail/Target detail consists of the names Pfenning and Ford. We scan the text, starting from the top of the passage, looking for the names Pfenning



  and Ford. We find them in only place, at the beginning of the second paragraph. We read a couple of lines above the names, and keep reading until a few lines after the names. It says "But in 1997 Michael Pfenning and Larry Ford at Tufts University in Medford, Massachusetts, apparently killed this ingenious idea by showing that it needed far more than the entire energy content of the Universe to work (This Week, 26 July 1997, p 6)". The line after that says the research of another physicist then resurrected the possibility of FTL travel, negating the implications of the research of Pfennig and Ford. Now we can answer the question. Do a any ny of the answer choices match the information given around the target area? Yes- E. Let's also eliminate. If we re-read what th e passage says about Pfenning and Ford, we can eliminate B, C, and D. None of them are supported by the information in the passage, so let's eliminate all of them without wasting too much time and with a minimum of fuss. A is tougher to eliminate. From the sentence that mention Pfenning and Ford, it seems their work does rule out the possibility of a space-warp drive. But if we read the next line, it says another researcher said it was indeed possible. So the Pfenning and Ford could not have "conclusively" demonstrated the impossibity of the FTL drive.

This is probably the most difficult type of Reading Comprehension problem. The question might look like this: "It can be inferred that the author makes which of the following assumptions?" "Which is an assumption underlying the last sentence of the passage?" "Which of the following, if true, would most strengthen the hypothesis mentioned in lines 17-19?" "With which of the following statements regarding chaos theory would the author be most likely to agree?" Strategy:

1. First, treat this type of problem as a Specific Target question. Look for a target in the question, find it in the text, and then look above and below it. Often you do not have to infer  very  very much, the answer remains within the text. 2. If the answer must be inferred and is not stated explicitly within the text, then choose the answer choice that can be inferred or assumed from the information given. Again, you should not have to infer very much – only one or two logical steps removed from the information in the passage. 3. Make sure that the answer choice you decide on does not violate or contradict the Main Ma in Idea of the passage - if it does, the answer choice is probably wrong. It can A) B) C) D) E)

First, let's try to deal with this question as a Specific Target problem. Is there a target in the question? Yes – the bubble. The bubble is first mentioned at the end of the second paragraph, and then discussed at length throughout the third paragraph. Remember, we have to look above and below that target area (as well as read the target area again), so quickly go through the second, third, and first part of the fourth paragraph. When you are finished, look at the answer choices. Can any of them be inferred from the information given in the target area? Well, we could eliminate C, D, and E for simply not being supported by the information given in the passage. B – maybe, but a This website stores data such as house moving through time seems pretty silly.

Since this is a Tone/Attitude question, we must look in the passage for descriptive words that tell us what the author thinks of Alcibierre and his theory.

This should give you the general structure or outline of the argument, with which you can answer the question. Remember to make brief notes about the structure of the text on your scrap paper. If you are looking for the organization of one paragraph, read the first and second sentence of the paragraph. That will give you a rough idea of what is the structure or organization of the paragraph. Which of the following best describes the organization of the second paragraph of the passage? Two investigations that support Alcubierre's theory are introduced A) B) Possible objections to to the uses of the warp drive are present, and then refuted refuted An objection to the practicality of the theory is raised, and then another work is cited to shore up the C) applicability of the original theory A work of theoretical physics that supports Alcubierre's theory is raised, and then another that refutes it is D) presented E) Alcubierre's theory is analyzed by a panel of several eminent physicists Explanation: 

Read the first sentence of the paragraph: "But in 1997 Michael Pfenning and Larry Ford at Tufts University in Medford, Massachusetts, apparently killed this ingenious idea by showing that it needed far more than the entire energy content of the Universe to work (This Week, 26 July 1997, p 6)".

Critical Reasoning Strategy

[We want to warn you immediately that this strategy is not the easiest way to do CR (the easiest would be read-and-answer), but it lets you get the most questions right spending less time per correct answer. The bottom line is that it won't be easy to follow this



  strategy but if you do, it will reward you]

1.  Read the question (this needed so that you would know what to look for and what to do: find an assumption, weaken, infer something or else; do not worry about the details in the question, read for keywords, such as strengthen, deny, or explain. Sometimes at the end of the Verbal section on the test, your brain won't even hol d a keyword, so you may want to write it down symbolically; e.g. + for strengthen or - for weaken. 2.  Read the passage (Read it very attentively because in contrast to Reading Comprehension, there is very little text here and mostly everything is important; try to read only once. Reread only hard texts). 3.  As you read, look for the problem in the passage (evaluate how convincing it is) 4.  Paraphrase the passage (this a very important step because when you do a paraphrase, you check whether you understood the passage and at the same time you extract the skeleton of the argument, making it easier to identify the conclusion and the assumption. Very often, the paraphrase of the passage will be pretty close to the conclusion. It is not surprising, since the

conclusion is the main point and evidence just supports it.) Your paraphrase should be as close to the text and as simple as possible so that you would understand it easily and at the same time could fully trust it. Do not make it too general nor too detail oriented. When you do a paraphrase, do it in three steps: Evidence1, Evidence2, and Conclusion; put "therefore" word before you start your conclusion, this will help you to set it off. Read the question again (now with more understanding of what is being asked; reading the question 2 times, will also help you to make sure you answer exactly what is stated and that you understand the question.) Answer before reading the answer choices (Why do this? Two reasons: one, if you can think of the correct answer or at least the general direction that the answer choice needs to be, you will identify it among the wrong choices much faster, thus spend less time reading the answers, which usually take 30 seconds to cover. The second reason is that often test takers are seduced by the author's wording. One reads a few words that were used in the passage and the brain identifies this choice with the passage, thus making it seem more right that it needs to be. The more problems you practice with, the more chance is you will guess the right answer even before reading it. And there is nothing more pleasant than seeing YOUR answer choices among the listed. ) Go through the answers, first time scan them for YOUR answer choice (usually you will guess correctly in 60-70% of cases), if you did not find it, reread them more attentively. Draw a grid to eliminate the wrong answers easier. Use "+" "+ " for a sure answer, "-" for a definitely wrong answer choice, and "~" or "?" for an answer that may be right or questionable. This will help to concentrate only on a few answer choices and will prevent you from reading same answers several times if you get confused or keep having troubles locating the right answer. A +

Many CR functionality, asdirectly well asask marketing, questions for an assumption or are based on them, such as weaken and strengthen questions. Also, assumption of an argument is one of the only You parts that we can influence to destroy or solidify an argument; thus if we can disprove an assumption, we personalization, and analytics. can negate the whole argument because the conclusion will not make sense.

In a case when evidence is completed with more info, we can still say that it is the assumption that the evidence we had was valid is being destroyed). Thus, to succeed in CR, it is crucial that you are able to extract an assumption fast; it will save you time on many questions. Practicing with assumptions does not take too long; 2-4 hours and your skills will be on top. PrivacyAlso, Policy you will be a better speaker and a more critical writer if you are able to see assumptions of the writer who argues against you because as we have said, if you can kill an assumption, you will damage the argument. For example, if we play with We will also cover one of the most important steps of the CR approach, paraphrase. Paraphrase allows you to check how well you understood the passage Marketing as well as to see the structure stripped. Paraphrase should not take you more than 5-10 seconds after you have read the passage. Sometimes it is useful to write down some complicated relationship or something that will help you to understand the passage better, Personalization such as a diagram, for example. Other than that, don't write down anything else, the passage that you read will be so short that you should be able to remember all the details without writing down anything.
