Browse the whole volume and grasp the whole picture. Make full use of 10 minutes before the exam, read through the whole volume, understand how many pages there are, the types of questions and the degree of difficulty, and make an estimate of the time required to complete the whole volume. If the estimate is optimistic, you should be more careful when answering questions, because some questions look simple, but in fact, the proposer has set a trap.
If the estimate is not optimistic, we should treat it calmly, because a short glance is not the result of careful consideration. If you lose confidence, you will set obstacles for yourself and reduce your chances of success. Careful examination of the questions, the first is easy, the second is difficult. Examination of questions is a necessary condition for answering questions. We should not only see the explicit conditions of the problem clearly, but also pay attention to the implicit conditions between the lines We should accurately grasp every symbol, data and chart, then associate the existing knowledge, identify the problem and choose the appropriate method.
When solving problems, stick to the principle of easy before difficult, so as to avoid thinking about a difficult problem for a long time, so that there is no time to do the problems that are easy to score, and lose sight of one thing and lose sight of another.
