2. Be good at summing up. That is to say, don't throw the test paper aside directly after you finish the question, write the questions you can't do in the wrong book, then analyze the thinking of this question (if you can't, you can consult your children's shoes and teachers), and compare it with similar questions to find out the law of solving this kind of questions.
3. Wrong title book. The wrong set of questions is really useful. As I said just now, after writing in the wrong book, we should sum up and find out the rules of this kind of questions. Also, you can do the wrong question again every few days to see if you really have it.
4. textbooks. Textbooks are the magic weapon for learning, and reading them thoroughly is the basic requirement for high scores. The formulas and theorems you said can be deduced by yourself according to the examples in the book, and then you can use them more when you do the problems and strengthen your memory when you make mistakes.
5, mentality. This is a must in the exam. If you are upset and your mind is blank, it will affect your performance.
