Do more problems, and the reason for failure is that there are too few problems. The teacher only spoke part of it. Most of the knowledge points are in the paper. There are new questions that you haven't touched, and that's where the difficulty lies. If you do too much, you will feel that the routine remains the same, that is, the method of asking questions has changed and the soup has changed. By doing a lot of problems, it is obvious that you can't do anything. Don't kid yourself, you can't do it. Stupid birds fly first, and teachers strictly improve their academic performance. Generally speaking, I won't tell you anything when I'm finished. Then how can there be progress? What's the point? You accumulate two questions a day, recite them if you can't, and then recite the types. No matter how you take the exam, it will change quantitatively and the form will remain unchanged. You should work hard at math. If you are not good at math, you should write, do, write, remember and recite more, knowing that you are poor at math. Do a lot of questions, treat the wrong questions as wrong questions, temporarily let parents or themselves test themselves in their spare time, don't look at the answers, and see if you will, won't ask again. If you persist in this way, you will certainly pass the exam that day.
