In the second stage, I listened to a basic math class.

At that time, a friend helped me get a lot of videos of remedial classes, and I was very happy. However, after listening to this class, it didn't help me much. Mathematics mainly depends on thinking and writing by oneself. I admit that there was inertia in thinking at that time, and it was much more comfortable to take classes than to rack one's brains to solve unknown problems. What I want to tell you is, don't be confused by those remedial classes and basic classes. They can't teach you by hand like a high school teacher, then give you corresponding questions, explain them to you, and have exams, so they won't have the same effect as high school.

In the third stage, I did 660 basic customs clearance questions.

I think this is a mistake. I hadn't read the review book at that time. I saw the foundation in the book, so I must have done it before the book. In fact, this "foundation" is not that "foundation", but probably the meaning of filling in the blanks, or mainly the examination of the basic knowledge points of the postgraduate entrance examination. In short, this is as difficult as the real question, so it is not recommended to do this directly after reading the book.

The fourth stage Li Yongle book review

All my math materials are from Li Yongle, because I think this teacher is very serious, patient and responsible. As for reviewing the whole book, I think my approach is also debatable. I took a pen as soon as I came up. Although there are still some problems I can do, it is undoubtedly a time-consuming and painful process. It took me almost three months to finish it, and I just finished reading the probability theory part. In the end, many things can't be done, but it will take a lot of time. Therefore, I think that for those who have a poor foundation in mathematics, they can probably read the whole book carefully first (and of course write it properly), and then do most of the questions they are not sure about for the second time. In fact, the difficulty of the whole book is still much more difficult than the real question, and it is normal that the question can't be done. But the exercises given later must be done well, which is very close to the real difficulty.

In the fifth stage, listen to intensive classes and review books.

I started listening to intensive classes to transfer knowledge quickly, but after reading the book completely, I really feel a little unwilling to think about the problem. Later, I spent three whole days listening to an intensive class of advanced mathematics, and I felt fine at first. Later, I didn't want to attend class or watch anything else, so I listened to the class blankly. Apart from taking some notes, I didn't get much. Later, I mainly looked at other subjects, which reduced the time for mathematics. Later, I saw someone posting on the forum that Teacher XXX spoke math well. I just listened to his video, and the result is really helpful. However, due to limited time, I only listened to my poor chapter. Line generation, of course, listened to Li Yongle. This is undoubtedly very good, and the probability class is ok. In short, for the remedial classes, I think the math intensive reading class is still helpful, provided that your review is ok, but I still feel a little mixed up. In addition, different people have different choices whether they listen or not. If you can study hard and think clearly about those problems, it should be better than what the teacher said. In short, remedial classes are not sufficient conditions for improving mathematics, and thinking by yourself can also achieve the goal.

The sixth stage, do the real questions.

I did the real questions carelessly, and many of them were done in less than three hours. I don't think this is good. Later, I didn't have much time to do simulation questions, but only did real questions. In short, I think it's better to do the real questions early, and then read the whole book in combination with what I don't understand. It's better this way. As for the simulation questions, I think we should also do them. Simulation questions are generally more difficult than real questions, and we should also create an examination atmosphere to simulate them. For most people, time is really tight during the exam.

To sum up, think more, write more, calculate more and speed up more.
