Of course not. Mathematics is still a basic subject, just like Gai Lou, one step at a time. Let me share my experience with you. I think the most time spent in the postgraduate entrance examination is mathematics, and the result of mathematics directly determines the success or failure of your postgraduate entrance examination. I began to study mathematics on February 25th, and finished reading advanced numbers and linear algebra in mathematics on March 20th. But it also took some detours. When I was studying mathematics, I read the textbook of Tongji edition, reading chapter by chapter and doing exercises chapter by chapter, so it was very slow, so the final result was that I was slower than my friends at the same time by a book on probability theory. The suggestion for everyone is to review the whole book, read a chapter casually, and then read Tongji textbooks. You don't have to do exercises in Tongji textbooks, just look at the examples in the whole book and do the corresponding topics in the whole book. However, for mathematics, just like English, it is not enough to read it once. I read the whole book three times, and I read it carefully every time. The third visit was at the end of August. And the third time to see the longest, about a month and a half. Every time you read it, you get different results. In addition, you can listen to the math class in the online school of Tiandao Postgraduate Entrance Examination for four times instead of three times, or you can listen to it three times instead of two times, because each time you feel different.
