1, as long as we start with the mathematical formula and find the starting point and process of its formula, we can win the basic knowledge. The specific method is to look at the formula first, understand and remember it (it is best to deduce it yourself, because what is deduced will not be forgotten, and even if it is forgotten, it can be re-deduced. Of course, even if you deduce it yourself, you should do it yourself, and consolidate it while doing it, because there is not much time to deduce it for you during the exam), then look at the exercises after class, think about how to solve it with the questions, don't calculate, just think, and then look through the textbooks to see how the formula theorem is deduced, especially the process and application cases. Pay special attention to why these knowledge points are produced.

2, mathematics to improve, the most important thing is not to do more questions, but to learn to choose topics to do! It's very important to sum up experience after finishing the questions! Take notes on the wrong questions, analyze the reasons for the mistakes and try to correct them; You can't do the problem blindly, but you must do it on the basis of understanding the concept, because if you do it blindly, sometimes mistakes or misunderstandings will be consolidated and it will be more difficult to correct them. (I have always been used to answering questions immediately after I finish a set of questions, because your thinking is the clearest at this time, so doing the problem is not a tactic of asking questions, but you can draw inferences. If the answer is wrong, then I can say that you basically did this question in vain, because you didn't answer, and you don't even know if what you did was right or wrong. You may copy the wrong answer in the exam and proudly say that I have done this problem; If it is a few days later, you may not be so impressed with how you understood and solved this problem at the beginning, so the effect will not be so good. So, I suggest you answer the questions after you finish. Of course, this varies from person to person. If you feel inappropriate, please follow your own method). For the typical problems in textbooks, we should deeply understand and learn to reflect after solving them: reflect on the meaning of the problems and prevent misunderstandings; Reflect on the process and prevent fallacies; Reflect on methods and strive for perfection; Reflecting on change and strategic positioning. This can not only deeply understand this problem, but also help to expand the income of solving problems and jump out of the sea of questions! Don't get caught up in the ocean of problems.

The above methods are suitable for self-study. Of course, you should listen carefully in class. I wish you an early success! ! ! !
