I am a graduate student, and my math foundation is not good. It is easier to count to three than to count to one. If you have no confidence in your math, I suggest you start reading textbooks as soon as possible. You should lay a good foundation first, understand the contents of the book first, and do all the questions after class. If the foundation is not good, review math next semester. After reviewing a lot of content, you don't need to take the exam, but as a foundation, it is best to start a comprehensive review. It's good to review the first book of advanced mathematics last semester. After all, I have to go to class, review the second book next semester, as well as linear algebra and probability theory. Try to read all the textbooks and exercises before the summer vacation, and start reading review books after the summer vacation, which can be completed in more than two months, so your math foundation should be good. Of course, there are still many questions to be done in the future: Li Yongle 600,400, 135 and real questions. Let's see how you're doing on the basics. I suggest that Li Yongle must do 600 and 400 questions well. I guess you've done everything I said. It should be no problem to get a 130+.

Finally, I want to make it clear that the postgraduate entrance examination has little to do with your background. The key is to carefully review the time and energy spent.

That's all for now. If you have any questions, please leave a message and keep asking questions.
