Chen Wendeng's Review Encyclopedia was recommended for more authoritative mathematics, while Li Yongle's and Li Zhengyuan's Review Encyclopedia was used for less basic mathematics. These books are thick and not easy to read, but the titles of Erli are traditional. Chen Wendeng's books have many problems that are off topic and emphasize skills. If the foundation is not good, you can also buy Li Yongle's "Basic Pass 660 Questions".

The review book is a combination of three subjects (advanced mathematics, linear algebra and probability theory). It looks very laborious. If you don't like it, you can buy Xinhua Publishing House's postgraduate mathematics tutorial series, including Dr. Zhao's advanced mathematics tutorial, Li Yongle's linear algebra tutorial, and Wang Shian's probability theory and mathematical statistics tutorial. Li Yongle's book is very classic. I think it is Li Yongle's linear algebra.

In the second round, you can buy Li Yongle's "Classic 400 Questions" and "Postgraduate Mathematics Super 135".

10 began to do the real problem and did it three times. These dozens of sets of papers contain many common problems, so we must pay attention to them.

There is still room for the final sprint to buy some simulation papers.

As a n experienced person, I think Li Yongle's books are more suitable for postgraduate entrance examination. I have attended his class, and his style of study is very rigorous and high-level. He is a real master. I wish you success in the postgraduate entrance examination. Come on!
