The designated book for the postgraduate entrance examination mathematics: Advanced Mathematics: It is best not to use the fifth edition of the sixth edition of advanced mathematics compiled by Tongji University Higher Education Press (Green), because the total review questions of the sixth edition are very close to those of the postgraduate entrance examination, and some of them are real questions for the postgraduate entrance examination, which is helpful for your preliminary review. Linear Algebra: The 4th or 5th edition of Linear Algebra compiled by Tongji University, the 2nd edition of Linear Algebra compiled by Tsinghua University Juma (purple), and Tsinghua University Publishing House (yellow), both of which are recommended by the Ministry of Education. Tongji's is relatively thin and compact. Tsinghua's is thick and complete. I suggest you choose Tongji at a high level and Tsinghua at a general level. In addition, it doesn't matter whether Tongji 4th and 5th editions are online books. Probability Theory and Mathematical Statistics: Zhejiang University Press (blue), the 4th edition of Probability Theory and Mathematical Statistics edited by Zhejiang University in its heyday, and Probability Theory edited by economic mathematics Wu Chuansheng. Although it is economic mathematics, the content is not bad. You can go on a field trip, which is available in general bookstores. It is mainly the practice of Wu Chuansheng's book, and there have also been adapted questions. In addition, you need a whole book and the topics in the review. I suggest you go to some postgraduate forums to see other people's experience posts. Is it boring for me to help you list all the counseling books here? You can choose something that suits you according to your own situation. Math mainly uses Li Yongle's books, and Chen Wendeng's can help.
