Many people are confused about which book to choose. Honestly, it's all the same. As long as you stick to one set, watch the online school video and brush the questions three or four times, you will find that all methods are natural and all roads lead to the same goal.
I started reading textbooks in March, brushed high numbers in June, brushed linear algebra in August, and brushed probability handouts in September, and cooperated with teachers on the online school of Tiandao Postgraduate Entrance Examination to explain videos, thus breaking the knowledge points one by one. Since the middle of 10, I haven't done a new problem, that is, I have repeatedly brushed the books and problems I have read before and constantly improved my knowledge system. It was not until the end of 10 that I took out the real question and started doing it at 1 10. I can get 130 points for the real questions of 10, including the number of real questions of 16, which is generally considered difficult. It is not recommended that you finish Li Yongle's 660 and decomposition exercises before doing Zhang Yu's 1000 questions, which are too much to digest. You have to understand that when you get to the examination room, if you can review every part as you did the first time, the whole paper will be 95% fine. So, choose a set of books, then stick to it and make sure you have mastered every question in that set of books, and you will be stable. I forgot the formula of the last question of mathematical probability and asked the first question, so the whole question was wrong. The score was 138.
For choosing books, it is much better to suggest that one book is done three times than three books. The more books, the better.
