1. One of the best users is different. Although one of the best is aimed at science and engineering candidates, one of the best majors has high requirements for mathematics, such as one of the best in mechanical automation and one of the best in chemical engineering. For details, please refer to the professional requirements of the admissions unit.

2. Number one: advanced mathematics accounts for 60%, linear algebra accounts for 20%, probability theory accounts for 20%, and number two: if you don't take infinite series, line-surface integral and probability theory, as far as its difficulty is concerned, I personally feel that number two is the most difficult, and there are few test sites for number two, which will inevitably mention the difficulty.

3. The textbooks are generally the designated higher education version of Advanced Mathematics, Tongji version of Linear Algebra and Higher Education version of Probability Theory. Just use the latest version. Every year, the Ministry of Education publishes a mathematical outline for postgraduate entrance examination, but it has not changed much. Please refer to the mathematics outline of 1 1. Because mathematics is a proposition of the Ministry of Education, you can review it according to the outline.
