Students can tell you not to worry. I passed the entrance examination for mathematics this year (128). I haven't reported to any classes, and the math postgraduate entrance examination is very basic. I think the advanced mathematics textbook you sent is the best review material. If you want to take the postgraduate entrance examination, mathematics is the key. Now is not the time for you to apply for the postgraduate entrance examination class. You probably don't even know the basics now. As my classmates said before, I can teach myself completely. Go to the bookstore to buy a tutorial book on advanced mathematics and read it for yourself (in fact, I tell you that when I was an undergraduate, I didn't listen to the teacher in class, and most of them learned it by myself after class. )。 Relax, you still have a long way to go for the postgraduate entrance examination. Don't be partial, prepare early and take your time.

Take your time. I just reviewed the math for the postgraduate entrance examination, and there are no questions I can do. Now you need to understand the basic concept of high number. There are also linear algebra and probability theory in the postgraduate entrance examination (the number 2 is not tested). Get the high number of the second year of high school first, and then take care of the latter.
