【答案解析】[听力原文]
Exams are a regular part of college course-work. Teachers give tests to determine what students have learned. Many students have difficulty taking an exam. They start to answer test questions immediately after receiving the paper. Actually, this is not advisable. Rather, other steps should be taken before you begin to answer the questions. First, glance over the test. Also estimate how much time you can spend on each item. For example, a ten-point essay question. If some questions appear easier than others, spend less time on them so that you will have additional time for the more difficult questions.
Many students either do not read test directions or read and ignore them. Read the directions carefully and then remember to follow them. Directions provide specific information about what you are required to answer and how you are required to respond. Unless the directions state that points will be deducted for question, it is advisable to answer every question on a test. Don"t leave blank spaces.
When you begin the exam, answer the easy questions first. These will actually take the least time to answer. Also, these questions may help you to remember and answer the more difficult questions. Don"t stay with a difficult item too long. Skip it. Answer the questions you do know and return to the more difficult items later.
Leaving a few minutes at the end of the exam to reread your answers and to complete the questions you skipped, checked to see that you responded to all of the questions, placed your answers on the answer sheet in a correct way, and followed all directions carefully. Only change an answer if you"re sure of the correction.
