The best way to learn mathematics is to write and calculate, but just looking at it is not enough. A good memory is better than a bad writing. If you prepare from the second year of high school, you will get high marks, which has little to do with your previous foundation, as long as you prepare well from now on.

You can go to Taobao to buy a video of mathematics postgraduate entrance examination: Dr. Zhao's advanced mathematics, his linear algebra and Yao's probability theory. They are the best teachers in all subjects and they are not expensive. They don't have much money to live after listening to the teacher's video, so they don't work so hard.

In addition, there are classic textbooks, advanced mathematics of Tongji University, linear algebra of Tongji University and probability theory. Sorry, I forgot which one it was. Use Li Yongle's reference books, but don't worry about it. You can read them in your junior year. Get the textbooks ready first.

I will take the exam this year. You can practice me if you have any questions. I hope it will help you, and I wish the postgraduate entrance examination a success. Come on! ! ! !
