Chen Wendeng's books are not recommended. I made that book several times, and then I talked to a professor in the School of Science. He immediately told me that this book is not good, and the topics are all from mathematics competitions in colleges and universities all over the country, which is obviously more difficult for students who take the postgraduate entrance examination, unless they are students majoring in mathematics in science colleges with a solid mathematical foundation, they may get a high score of 140 or above with this book. But for others, it's probably nothing to watch it a few times.

For non-mathematics majors, it is better to lay a good foundation and improve their skills step by step. If you really lay a good foundation and have certain skills, it is not difficult to get a good score of 125- 135.

Li Yongle's complete set is quite good. If you have finished the review guide of Li Yongle and Li Zhengyuan series, you can do the simulation questions. There are several kinds of simulation questions! I remember doing Li Li's 400 questions, and Li Li scored 135. After doing it, it was quite rewarding.

I failed the exam that year 125, only 1 18. Maybe my foundation is really poor!
