Now look at the textbook of advanced mathematics and do exercises after class. In the summer vacation, you can almost start reading the whole book of mathematics. When reading, cover up the answers and think for a while. There is really nothing to think about. It takes a long time to review math. Maybe you read the review book once, start reading it for the second time, and find that you have almost forgotten the previous content, which is normal. Do math problems nonstop every day. 1 1 month later, you can do real questions and test your level with real questions. Actually, Math III is quite simple. Send you the word 12, which is my experience in the postgraduate entrance examination: review well, adjust your mentality and don't give up.
