1. It has been many years since I took the postgraduate entrance examination. During the period, I heard that Math 4 was merged into Math 3, so Math 3 should include calculus, linear algebra and probability theory. At that time, I was a student of economics and management, learned three, and taught myself one for the postgraduate entrance examination.

2, look at the problem, it is estimated that you are a student majoring in humanities, and undergraduate students should not take math classes. If high school mathematics is easy to learn, you can also consider it. If high school mathematics feels a little difficult, it is not recommended to take the exam. It's also good to study law and public administration.

3. If you are determined to test the number three, it is estimated that you are majoring in economics and management, finance and quantitative economy in economics; Management science and engineering, operational research of management science is not recommended, and mathematics requirements are high. You can take an examination of other majors in business administration or applied economics.

4. Advanced mathematics is still difficult. Calculus depends on logic, linear algebra depends on clear thinking and calculation ability, and probability depends on abstract thinking. Without guidance, self-study is still a bit difficult. You can go to science and engineering classes. It's free anyway. Why not use it?

5. In terms of teaching materials, Tongji Edition is recommended for advanced mathematics, but there are different opinions on linear algebra, and Zhejiang University Edition is recommended for probability theory.

6. Chen Wendeng's series of counseling books are famous for their math counseling for postgraduate entrance examination, while Li Yongle is famous for others. Personally, I think Chen Wendeng is enough, there is no need to do so much.

If you are satisfied, please adopt it. Thank you!
