Test strategies : f f




• Read the directions carefully f f f




• Know if you are penalized for guessing f f f f f f




• Answer easy questions first f f f




Answering options : f f




• Improve your odds, think critically f f f f




• Hide the options, read the stem, and try to answer
f f f f f f f f f




Select the optionthat most closelymatches your answer
f f f f f f f f




• Read the stem with each option f f f f f




Treat eachoption as a true-false question, and choose the “most true”

Strategies to answer difficult questions : f f f f f




• Eliminate options you know to be incorrect f f f f f f




• Question options that are totally unfamiliar to you f f f f f f f




• Question options that contain negative or absolute words f f f f f f f




• “All of the above” f f f




If you know two of the three options seem correct, “all of the above” is a strong

possibility

• Number answers : f f




Toss out the highand low and consider the middle range numbers

• “Look alike options” f f




Probably one is correct; choose the best but eliminate choices that f f f f f f f f f f




mean basically the same thing, and thus cancel each other out
f f f f f f f f f f f




• Echo options : f f




If two options are opposite each other , chances are one of themis correct

Remind yourself that you are well-prepared and going to do well. If you find yourself

anxious, take several slow, deep breaths to relax. Don’t talk about the tests to other

This unit includes 1000 multiple choice questions. The purpose is to assess the breadth

of student’s knowledge and understanding of the basic concepts of organic chemistry.

Remember that the multiple choice questions :
f f f f f f f




1. are not simply definitions. f f f




2. require application of recalled information, not simple recall. f f f f f f f




3. require fine distinctions between correct and nearly-correct statements. f f f f f f f




4. emphasize conceptual understanding f f




These questions have been especially designed to cover all the important concepts
