I think the first round of review should be to thoroughly understand the textbook. Generally, the recommended textbooks are advanced mathematics Tongji 5th Edition, online generation Tongji 4th Edition or Renmin University of China Press, and the probability is Zhejiang University 3rd Edition. It will take about two months.

Only in the second round can we improve and review comprehensively with counseling books.

Personal suggestion: In the second round, use Li Er's Mathematics Review Book+analysis of real questions over the years. Deng Ge's calligraphy skill is too high, and the foundation is not suitable.
