                                           Advice on Test Taking

     ★Read the directions carefully. This may help you not make careless mistakes.

     ★If there is time, look through the whole test quickly. If you can, take short notes to help you

remember answers that come to your mind on the test or answer sheet (纸). But remember to ask if that

is allowed!

     ★Answer questions in the right order(顺序): 1. Answer easy questions first to build confidence (信

心). It may also help you answer more difficult questions later. 2. Then answer difficult questions or the

most important ones. If you need to choose answers, first find those answers that are probably wrong. If

there are two answers with similar (类似的) ideas, both of them may be wrong. Then choose the best

answer. If you still can't tell the right one, believe the first one that comes to your mind. If you need to

answer some questions, give short descriptions of your ideas and then put them in order.

     ★Review: Don't leave as soon as you have finished all the questions. Review your test to make sure

that you ◎have answered all questions ◎did not choose answers that you don't really want ◎did not

make simple mistakes
