How to Solve MCQ

 

 

Multiple choice questions usually include a phrase or stem   followed by three to five options:  Test strategies:    Read the directions carefully 

Know if each question has one or more correct option Know if you are penalized for guessing Know how much time is allowed (this governs your strategy)   Preview the test Read through the test quickly and answer the easiest questions first Mark those you think you know in some way that is appropriate   Read through the test a second time and answer more difficult questions You may pick up cues for answers from the first reading, or become more comfortable in the testing situation   If time allows, review both questions and answers It is possible you mis-read questions the first time Answering options Improve your odds, think critically: 

Cover theoption options, stem,matches and try your to answer Select the thatread mostthe closely answer Read the stem with each option Treat each option as a true-false t rue-false question, and choose the "most true" Strategies for answering difficult questions:  1.  Eliminate options you know to be incorrect If allowed, mark words or alternatives in questions that eliminate the option 2.  Give each option of a question the "true-false test:"   This may reduce your selection to the best answer 3.  Question options that grammatically don't fit with wit h the stem  4.  Question options that are totally unfamiliar to you  5.  Question options that contain negative or absolute words.  Try substituting a qualified term for the absolute one. For example,  frequent  frequently ly for always; or typical for every to see if you can eliminate an

option 6.  "All of the above:"  If you know two of three options seem correct, "all of the above" is a strong possibility 7.  Number answers:  toss out the high and low and consider the middle range numbers 8.  "Look alike options"  probably one is correct; choose the best but eliminate choices that mean basically the same thing, and thus cancel each other out 9.  Double negatives:  Create the equivalent positive statement 10. Echo options:  If two options are opposite each other, chances are one of them is correct 11. Favor options that contain qualifiers The result is longer, more inclusive items that better fill the role of the answer

 

12. If two alternatives seem correct,  compare them for differences, then refer to the stem to find f ind your best answer Guessing:    Always guess when there is no penalty   for guessing or you can eliminate elimi nate options   Don't guess if you are penalized for guessing  and if you have no basis for your choice   Use hints from questions you know to answer questions you do not.   Change your first answers  when you are sure of the correction, or other cues in the test cue you to change. Remember that you are looking for the best answer,  not only a correct one, and not one which must be true all of the time, in all cases, and without exception. 
