Review the exercise books and make some proofs for the key questions. You should clear your mind and master as many methods as possible. It's best to master the simplest one, and then you can draw inferences from your previous mistakes.
Do some extracurricular exercises if you get high marks. Do one or two mock test papers. Maybe your teacher has asked you to do a lot. Please have a look again. Pay attention to what the knowledge points are in each exam and whether you can do the same type of questions.
In fact, math doesn't need to be reviewed like Chinese and English. The foundation is solid. You can do comprehensive questions, and there are only a few days before the exam. Don't be too nervous when you do the problem, or you will simply say that you can't think and you can't think. Don't be nervous about the problem. Have enough time to think about them in different ways on draft paper.
Finally, I wish you success in the exam.
