First of all, take the postgraduate entrance examination to learn mathematics and follow the right teacher. If you have a good teacher to take you to study, you will take fewer detours. Now there are many famous mathematicians on the Internet, such as Zhang Yu, Tang Jiafeng and so on. Personally, I feel that Zhang Yu's postgraduate mathematics is not based on Tang Jiafeng's teaching, but mathematics is a basic course. Tang Jiafeng's video is available in the mile. If the economy does not allow, you can watch it directly from the mile. If the economy allows, you can take classes. Secondly, what should I do if I encounter problems I don't understand in learning mathematics? At this time, the best way is to have one or two research friends, preferably more serious, so as to promote and communicate with each other. Finally, if you want to take the postgraduate entrance examination to improve your math scores, you must brush more questions.

As an experienced person, my advice to you is to finish reading the book first, no matter how difficult it is. When you read 1, do the example once, and then read it again. When you watch it for the second time, do all the questions after class, then watch it for the third time, watch it for the third time, or do the questions in each chapter after the third time. Finally, do a simulation test and feel like you are doing it. Mathematics is really important, mathematics is really important, mathematics is really important! ! ! ! ! ! !

I suggest you sign up for a remedial class and follow the teacher's guidance, so that you can be more confident in the exam. Several friends around me took part in two-day classes every weekend by signing up for classes. After months of counseling, they were admitted to their dream university as they wished. Listening to their lectures, the teacher will give one-on-one guidance, teach some problem-solving skills, how to grasp the time of answering questions, how to control risks and so on. If you teach yourself, the effect may be worse, especially if you don't know the important and difficult points, it is easy to go astray in the review direction, which wastes both time and energy. However, we must be cautious in applying for classes, depending on the strength of teachers, teaching experience and whether there is a special one-on-one service for class teachers.
