1. Make a collection of personal mistakes, turn it over when you have nothing to do, look at yourself, and you will certainly gain a lot. Choose a better reference book. There are not many reference books, but one main one is enough.

2. What should I do if I encounter difficulties? First of all, we should try our best to solve it through our own efforts. If it can't be solved, we should also find out why it won't and where the problem lies. I often say: never expect not to encounter problems, but never allow yourself not to understand where the problems are.

When you can't solve it yourself, you can solve those problems by discussing and asking the teacher. The solution is by no means that you can do it with the help of others, but after you can do it, look back and compare the reasons why you can't, and be sure to find out the reasons, otherwise you will lose an opportunity to improve and lose the meaning of doing the problem.

4. How to jump out of the sea of questions? I think everyone must be very concerned about this topic, because physics is difficult to understand, chemistry is difficult to remember and mathematics has endless problems. But the topic is the heart of mathematics, and it is absolutely impossible not to do it. And there are so many problems before us that it seems endless. Try the following methods. First of all, on the basis of completing the homework, analyze how each topic is investigated and what knowledge points are investigated.

5. Is there any other way to examine this knowledge point? Second, when you continue to do the problems, there is absolutely no need to work out every problem in detail. As long as you have read it, you can classify it into the problems we analyzed above, and you can skip if you know the way to solve the problem! In this way, for every knowledge point, we can master the examination method, which is the real improvement.

6. If you don't realize this, doing the problem is just doing the problem, "the topic". You can't jump out of the problem, you can't see the essence of the problem, you can't meet new problems, and you are a little different. What can you talk about? How can we get rid of the ocean of problems that plague you?

7. Diligence and perseverance are the necessary conditions for learning mathematics well. Writing more and thinking more, combining the two, is the most important thing, and it is also the magic weapon to learn mathematics and even science well. I think, as long as we stick to the above points, students' grades will certainly catch up!
