Read every chapter and section of the textbook carefully, and then do all the exercises after class. This is the foundation. As long as you stick to it, you will certainly gain something. At that time, I started reading textbooks in March, that is, sorting out the knowledge points of textbooks, doing after-school questions, writing down what I can't do and practicing more. It was not until the summer vacation in July that I began to read review books.
Reviewing the whole book is good for the postgraduate entrance examination. The test sites are detailed and there are many topics. We also scored three. A classmate is poor at math and slow in reading. He read the whole book four times without doing any real questions. 12 years, and he also got 127. Therefore, the whole book should be good-looking, and the questions obtained in the basic postgraduate entrance examination are all on it. If you can really read the whole book carefully two or three times and do the real questions twice, you should be able to go to 130.
