Many candidates wonder whether or not to guess the answer to questions about which they are not certain. In this
section of the examination, as a correction for haphazard guessing, one-fourth of the number of questions you answer
incorrectly will be subtracted from the number of questions you answer correctly. It is improbable, therefore, that mere
guessing will improve your score significantly; it may even lower your score, and it does take time. If, however, you
are not sure of the correct answer but have some knowledge of the question and are able to eliminate one or more of
the answer choices as wrong, your chance of getting the right answer is improved, and it may be to your advantage to
answer such a question.
Use your time effectively, working as rapidly as you can without losing accuracy. Do not spend too much time on
questions that are too difficult. Go on to other questions and come back to the difficult ones later if you have time. It is
not expected that everyone will be able to answer all the multiple-choice questions.
