Start with the basics, practice more simple questions and basic questions, and don't be arrogant. What you see is different from what you do. Don't cling to difficult problems. There are only a few difficult questions in a test paper, and the rest are very simple. High scores are accumulated by scores of many simple questions. Many simple questions complicate the difficult ones. Pay attention to the collection of wrong questions. You need to know where your thinking is different from the answer to this question. You should know how to deal with this problem. All math problems have their own mode of thinking. What you have to do is to reflect the starting point, thinking mode and solving steps of a problem in your mind when you see it. Just do it step by step (my math 1 48, now 100).
