Multiple choice test taking tips

  • Read the question before you look at the answer.
  • Come up with the answer in your head before looking at the possible answers, this way the choices given on the test won't throw you off or trick you.
  • Eliminate answers you know aren't right.
  • Read all the choices before choosing your answer.
  • If there is no guessing penalty, always take an educated guess and select an answer.
  • Don't keep on changing your answer, usually your first choice is the right one, unless you miss-read the question.
  • In "All of the above" and "None of the above" choices, if you are certain one of the statements is true don't choose "None of the above" or one of the statements are false don't choose "All of the above".
  • In a question with an "All of the above" choice, if you see that at least two correct statements, then "All of the above" is probably the answer.
  • Usually the correct answer is the choice with the most information.

Preparing for tests

  • Be rested and comfortable. If you take a test when you are hungry or tired you won't perform well.
  • Know what to expect. Learn ahead of time the kind of test you will be taking, where and when it will be held and what materials to bring. Arrive on time to avoid last-minute pressure.
  • Expect some anxiety. Being concerned will help you do your best on a test.
  • Avoid worried test-takers. Extreme nervousness, called test anxiety, will interfere with your work. Remember, test anxiety is contagious and unproductive.

uparrow imageBack to top of page

Reducing test anxiety

  • Keep a positive attitude. Decide to do your best and don't blame yourself for what you don't know.
  • Concentrate on the test. Don't worry about your ability, the behavior of other people, the number of questions or even short memory lapses. Pay close attention to one question at a time. This kind of concentration reduces anxiety.
  • Relax. If you are too nervous to think or read carefully, try to slow down physically. Change your mood by taking several slow deep breaths. Then start to work.
