I don't know what your foundation is. If you don't do it well, you can't do it in a hurry I suggest you read the review book carefully. You must do it. It's no use just looking.
Then, do real questions, do them over and over again, and there is a 660 questions by Li Yongle, all of which are multiple-choice questions to fill in the blanks. I think this is very good. Doing more can improve the correct rate of choosing to fill in the blanks, which is very helpful for grading.
Most people don't know how to do the problem at first, so don't be too depressed. Hehe, as long as you work hard, it will be much easier to do the problem slowly. When doing the problem, I will turn over the review book and focus on the knowledge points that I can't. You can write down unfamiliar knowledge points and flip through them when you have time, especially the formulas generated by many lines, which are really easy to be confused, hehe.
Your requirements are not high, 90 points is still easy to achieve, hehe.
Mathematics postgraduate entrance examination is not difficult, but many people say that mathematics is difficult, so many people find it difficult, and then they say it is difficult.
Also, it is important to have confidence and believe that you can succeed, hehe, well, I wish you success! I wish you success in your exam! !
