1. Carefully examine the questions (after you get the test paper, don't do it in a hurry, pay attention to carefully examine the questions first). First, examine the meaning of the question, divide the meaning of the question into different levels, and analyze which part of the knowledge points to examine.

2. Check for leaks and fill gaps, and overcome knowledge weaknesses. If the knowledge is defective, we should focus on reviewing this problem. If you do it quickly, you should also sum up what the knowledge points of this problem are. At the same time, we should seriously sum up the problems encountered in the previous learning process.

3. Multiple solutions to one question, multiple solutions to one question, and improve the flexibility of solving problems. Some problems can be analyzed from different angles and different solutions can be obtained. Multiple solutions to one problem can cultivate the ability to analyze and solve problems flexibly. When reviewing, we should think from different angles and classify all kinds of exercises, so as to integrate what we have learned and improve the flexibility of solving problems.
