2. Do more exercises and test papers. In the review, we should do more exercises and draw inferences from others, so that students can understand all kinds of questions and master the methods. After that, the teacher should sum up and correct the problems in time. For sexual problems, we should correct them together in class and further strengthen our practice. Students are forbidden to make repeated mistakes and give individual counseling for individual problems. Make students know what kind of questions they are and how to do them as soon as they see the exercises. After reviewing each unit, test it in time. The test questions are novel, comprehensive and flexible, with many knowledge points and wide coverage. After the exam, teachers should not only carefully analyze and record students' defects, but also prescribe the right medicine in time, and concentrate on the next exam so that students can know this and that.
