Haven't you studied for a few years? I suggest you read the textbook completely and find someone who is good at math to help you. After all, many specific problems can't be solved by yourself.

Besides, after listening to your lecture, have you signed up for the class? Take out your high school energy to treat math now. Mathematics is different from politics. You must learn it from now on. Don't bother to solve the problem in time. Prepare a notebook by yourself, and accumulate and collect your own answering skills or questions that you can't do. In addition, we should grasp the outline and key points of the exam, and don't review blindly.

Finally, I wish you a successful postgraduate entrance examination ~ ~ There is a second interview today, and I hope my suggestions can help you to come to Baidu to relieve the pressure.
