When I took the exam, it was still the world of Wendeng Huazi. I don't know now. At that time, I remember that Cai bought the book in the class, and the line read it. The books written by Wendeng are scanned first, then the textbooks and questions. There are also salvation punching classes, peer-to-peer classes and so on. Be sure to apply for one (I applied for Du Wen in those years, but now I don't know which is better). I made up my advanced math class, and the math was 120 when I took the postgraduate entrance examination, so I think this routine is still ok.

As for specialized courses, you can contact the teachers who want to apply for the school. Must be a tutor and counselor for master students. Boring, you'd better give a question! Then get the real questions and face the textbooks needed for the exam. Generally, each chapter has big questions, and each chapter has limited knowledge points. 3-5 years of real problem summary! When my wife took the postgraduate entrance examination, 4-5 people guessed all the knowledge points of the big questions!
