1. Prepare an error correction book, and write down in detail the problems that you often make mistakes but can't do (ideas, steps and error-prone points (marked with red pen to remind yourself). Read it carefully several times before each exam.

2. Do more sets of papers, don't do them next to each other, focus on one type, for example, do a series first, and do all the questions about the series in several sets of papers before doing the next type of questions. This way, thinking is more concentrated and it is easy to find the law. I feel that anything important can be recorded in the corrected book at any time. )

3. Always work with someone who is better at math than himself. He will tell you some of his problem-solving skills and ideas. After mastering a little skill, you can often do better than doing it (whoever does it faster has the same answer. . . . )

4. Do more math problems when you are bored. At first, I felt very painful. When I feel bored, people who do math problems are simply not human. But later, I found that after finishing several sets of papers and doing math problems with my deskmate, I really wanted to do some math problems when I was bored. ) In this way, I really unconsciously put mathematics on the table. Ask your classmates and teachers if you don't understand.

5. Important formulas must be memorized. Many problems start with formulas, but formulas are not good and there is no way to start (such as the relationship between sine and cosine). The mathematics volume of the college entrance examination mainly looks at functions, dihedral angles, series, probability ellipses, hyperbolas, parabolas and so on. You should focus on reviewing these contents.
