If you are basically zero-based, it is recommended to read the examples in the textbook first, just do the examples, and don't do the exercises later.

Then buy the lecture notes of advanced mathematics, linear algebra and probability and statistics. If it is still difficult to understand, I recommend Pan Xin's Happy Postgraduate Mathematics Series. This series of books is relatively easy to understand, and you can quickly understand and master some basic problem-solving routines with zero foundation. There are many problem-solving routines in it, which beginners can master quickly, but may not be deep enough.

If you have a certain foundation, advanced mathematics, I recommend Tang Jiafeng. You can try his book review. Mainly look at the high number part, linear algebra, I recommend Li Yongle's, he summed up the questions and knowledge points better.

Li Yongle and Wang Shian's "660 Questions of Postgraduate Mathematics" are recommended as auxiliary exercises that can be used. It will be a little difficult, but it will be more accurate. If you are afraid of difficulties, you can choose Tang Jiafeng's 1800 math exam, which is more gradual, but too heavy.

If you have enough time, try to buy real questions over the years and do it by analyzing the types of questions: for example, the real questions in mathematics for postgraduate entrance examination are all refined over the years.

Analysis ",and then do the simulation volume.

If you don't have much time, buy a simulation test paper to do. Tang Jiafeng's "The Last Eight Sets of Questions" is more difficult and has a good foundation. If you want to be higher, you can choose this set. Li Yongle and Wang Shian's "6+2 simulation questions" are relatively simple, focusing on mastering some foundations, depending on your level choice.
