2. The score and difficulty of the test content.
Advanced mathematics appears in multiple-choice questions 1, 2, 3, 4, fill-in-the-blank question 9, 10,12. The convergence and divergence of improper integral, the existence of primitive function, the properties of differential equation solution, the continuity and derivability of one point are investigated, and the limit is obtained by variable limit integral.
Linear algebra appears in multiple-choice questions 5 and 6 and fill-in-the-blank questions 13. It examines the similarity, quadratic form and determinant calculation of matrices, which belongs to basic knowledge points and is not difficult.
Probability theory and mathematical statistics appear in multiple-choice questions 7 and 8 and fill-in-the-blank questions 14, and investigate the relationship between common distribution, numerical characteristics, random variables and confidence intervals. Multiple choice questions 7 and 8 are not difficult, and you can score by careful calculation. Fill in the blanks 14 is a bit difficult and needs more thinking.
