Prepare the wrong book. Every time I do an exercise, the wrong questions will be copied into the book. Do it a few times more when you have time to deepen your impression. Read it several times before the exam to avoid repeating the same mistakes.
Listening carefully in math class and following the teacher's ideas are much better than spending twice or even more time reviewing by yourself after class.

It's important not to read when you do your homework. If you can't do that problem because you don't remember the formula, then leave it blank first, and then open the book after all the homework is finished, find out the formula and remember it firmly, reminding yourself in your heart: if this is an exam, you will lose 5 points or even more because you don't remember this formula; If you come across a formula that is hard to remember, copy it on paper and spend a little time looking at it every day to deepen your impression.
