1, listen carefully. Some students don't listen to lectures in class, don't watch after class, don't make materials, write down formulas with textbooks before the exam, sum up knowledge points, and the exam results are in a mess.

2. Take math notes, especially understanding different aspects of concepts and typical examples.

3. Establish a mathematical error correction book. Write down error-prone knowledge or reasoning in case it happens again. Strive to find wrong mistakes, analyze them, correct them and prevent them. Reach a deep understanding from the opposite side; Guo may get to the bottom of it, suit the remedy to the case, answer questions comprehensively and reason closely.

4. Memorize mathematical laws and conclusions. High school math doesn't rely on rote memorization, but it doesn't mean you don't. The basic laws and conclusions should still be remembered. If you memorize it, you can use it flexibly.

5. Do some math extracurricular problems on the basis of ability and increase self-study.

6. Repeatedly consolidate and eliminate forgetting before school.
