Postgraduate entrance examination is equivalent to the second college entrance examination. Anyone who has experienced the college entrance examination knows what review is. It is nothing more than constantly doing questions, consolidating the knowledge in the book over and over again, and then getting familiar with the routines of the questions, which can cope with the flexible questions in the examination room.

To put it bluntly, the exam is to do the problem. How? The topic is based on the content of the book. Therefore, the content in the book is the most important. Are you familiar with all the knowledge in the book? After reading the book twice, you should know. But it is not enough to know, the content of comparison is dead and easy to forget. Then you need to form a knowledge frame in your brain and learn to think in connection. Note: this is difficult to do, you need to try it yourself. Once you master it, it will be very effective for all your courses.

So what do you think we should do now? First of all, books must not be lost, and they need constant review. This doesn't mean that you have to read it every day and review those important knowledge points every once in a while. This requires you to strengthen it by doing problems. Like your third item, if you can't do it, you should pay special attention to this knowledge point, because you won't do it if you forget it. If you can't do it after turning over the books, you must be unfamiliar with the knowledge points and can't use them flexibly. This requires asking more questions to find the feeling. Why can't you just read a book a few times and lose it? Because our subconscious is often overconfident. For example, if we read the book twice and still understand it at that time, then we will think that we have been very clear about the contents of the book for a long time, but in fact, our brains have forgotten a lot of things at this time, and only when we do problems or take exams can we find that, alas, we have forgotten everything. This is a great feeling for me (I don't know if you have it). Of course, the most ideal thing is that you are familiar with the knowledge points, so that the context of knowledge is clearer (but I think it is generally a teacher who has taught this course for a long time).

Think about the topic you did. It's definitely useless to talk about sea tactics. Because there are more topics than textbooks, you can't remember everything in the book. How can you remember so many topics? Therefore, refinement is the key. A good exercise book is enough. If you don't understand, you must understand, ask the teacher or study it yourself. It will be fun and help your confidence. Mark the places where you often make mistakes. Proofs such as Lagrange's mean value theorem mentioned above are very vivid. Of course, many of them have fixed routines (these must be clarified first). Know what you have done. Once you feel it, you won't be afraid next time.

Having said that, in a word, my conclusion is that mathematical feeling is very important. In the case of clear review focus, do more questions (not blindly), find more feelings (during this period, your thinking will be exercised, don't give up when you encounter difficulties), find feelings, and you will be familiar with mathematics every time.
