Number two includes high numbers and linear algebra. You need to know these two subjects and be able to integrate them. You have to test many knowledge points in a postgraduate math problem, and you must run through all the knowledge points you have learned.

English requires CET-4 or above, but the English direction of graduate students is different from CET-4. Even if you have CET-6, you should work hard on English for postgraduate entrance examination.

Politics includes Marxist philosophy, political economy, introduction to Mao Zedong Thought, Deng Xiaoping Theory and current affairs politics, among which philosophy and political economy are the key points, and current affairs politics is the easiest to score, but you should pay more attention to current affairs. I suggest reading the first and eighth editions of this newspaper frequently. The content is objective and full of important events.

I won't say much about specialized courses, and what others have said is quite in place.
