I have some suggestions here, please follow the following steps. I suggest you find a more detailed counseling book similar to the college entrance examination research, preferably in separate volumes, rather than a comprehensive version of 5.3; There should be four parts: knowledge points, examples, variant questions and comprehensive exercises; Step, 1. Read the textbook first to understand the knowledge. 2. Do examples, understand the ideas of examples, and pay attention to fully understand the application of mathematical formulas and examples. 3. Do the variant questions and reflect on the examples after completion. 4. Section 1 generally has 3-4 types of examples. After completion, do comprehensive exercises and reflect on the answers. 5. It's very important, five stars. The next day, recite the answers. One more thing: Science in senior high schools mostly appears as questions, so it is suggested to do a class every two days (because review is needed), review what you have learned every week, pay attention to the connection between knowledge points and the application of questions in science, so as to know what kind of questions you want to know, what kind of knowledge you want to test, and what kind of questions-know, know-question, gradually consolidate the foundation and make a book, and then do the college entrance examination questions.
