I read Wendeng Chen's review guide at 1 minute, which is very good! LZ, just flip through. The probability of high numbers is there, the summary is very refined, and the examples are very representative. The real problems were put forward by Li Yongle, many of which offered different solutions. Li Yongle's 400 questions are also recommended for the simulation questions, which are difficult but focused. I'm going to count these three books and look back and forth.
The math test for postgraduate entrance examination is different from the final exam of 1, so it is enough to review the textbooks for the first time because the difficulty is limited.
When we were preparing, the books on mathematics were not authoritative enough except Chen Wendeng and Li Yongle.
