Secondly, I haven't read your book, so you'd better not use that one. The third edition of Probability Theory and Mathematical Statistics published by Zhejiang University is commonly used in probability, and the sixth edition of Linear Algebra published by Tongji University is now available. I used the fifth edition at that time, and advanced mathematics was also the fifth edition of advanced mathematics published by Tongji University. Well, I got the first place in the exam. This is recommended according to the highest difficulty.
Third, I suggest you look for last year's math syllabus for postgraduate entrance examination and find out the scope of the exam. Those who are not in the syllabus will not be tested. Counting to three is much less than counting to one. This is easy to find.
Fourth, now you can look at your own textbooks or look for the books I mentioned above. Because the back review uses special review books, including those from Li Yongle and Wendeng Chen, which are basically used for postgraduate study. You can't buy it until the new outline comes out this year, because the outline is the authority, and everything revolves around it. Li Yongle is easier to use than Chen Wendeng.
Fifth, as for the foundation you said is not good, there is no good way. In mathematics, you should read more books and do more problems. You still have plenty of time. Postgraduate entrance examination is a miracle, because all improvement methods must be based on a certain foundation.
That's all for now. You can visit more postgraduate forums. If you have any questions, you can also ask others and see their experiences.
Finally, I would like to advise that the most important thing for postgraduate entrance examination is planning and persistence.
Supplement; I don't know about accounting, but except for a few subjects such as medicine, psychology, computer and postgraduate entrance examination, it depends largely on the school you want to apply for. Every year, reference books will be given in the graduate professional catalogues of various schools, and some will give several books, so you need to collect information.
1. Which book do the students in their school use in class? Then you should mainly read that one.
2. In recent years, teachers' class notes and assignments are the best, but there is no way to do it.
The most important thing is the real question. The real question is king. If you don't do it seven or eight times, it won't work at all.
Like real questions and notes, some of them will be sold, usually from our school or graduate school. You'd better ask your classmates who were admitted last year. It would be better if there were seniors in that school.
