My postgraduate entrance examination is management, and I also count three books. Well, it looks like this. Number three mainly talks about linear algebra, probability theory and advanced mathematics. I don't know if you have studied advanced mathematics during your undergraduate course. I learned too much math in my freshman year. It's March. Now, I think? What we have to do in early summer and summer vacation is to thoroughly read the books and go through all the teaching materials. Where are the textbooks? That's how people usually buy it. Advanced Mathematics and Online Buying Tongji Publishing. The fifth edition, but the sixth edition of Shu Gao has also come out. Probability theory bought from Zhejiang University, third edition. Of course, if you have such books now, it doesn't matter if you don't have these versions. The general content is similar. Just be thorough. Besides, such books are hard to find now. I searched Dangdang for a long time, but it was out of stock. Fortunately, I went to college in my freshman year, which was from Tongji, but not that version. It can still be used. In mathematics, you should find out all these textbooks first, and then take the time to go over them before the summer vacation. There are exercise books for review and so on. Generally speaking, Li Yongle and Chen Wendeng are famous. As for who is better in the two books, different people have different opinions. As for me, I bought it from Li Yongle. Li Yongle has 660 questions, which is a good book. You can look for it, Dangdang has it online. This book is solved, you can continue to buy his 400 questions. Or you can get to know Chen Wendeng. As for me, I prefer Li Yongle's. Well, that's about it. Remember to read the textbook through! ! ! Then do the problem. Well, I hope these are helpful. Everyone is a graduate student. Hehe ~ Be confident and persist. All right, come on! ^^
