1, the content is different.

Mathematics 1: advanced mathematics, linear algebra (determinant, matrix, vector, linear equations, eigenvalues and eigenvectors of matrix, quadratic form). Probability theory and mathematical statistics (random events and probability, random variables and their probability distribution, two-dimensional random variables and their probability distribution, numerical characteristics of random variables, law of large numbers and central limit theorem, basic concepts of mathematical statistics, parameter estimation and hypothesis testing).

Mathematics 2: Advanced mathematics (function, limit, continuity, one-variable function calculus, ordinary differential equations), linear algebra (determinant, matrix, vector, linear equations, eigenvalues and eigenvectors of matrices).

2. Different majors apply

All two disciplines and majors in 20 first-level disciplines, such as mechanics, mechanical engineering, optical engineering, instrument science and technology, metallurgical engineering, power engineering and engineering thermophysics, electrical engineering, electronic science and technology, biomedical engineering, and first-level disciplines awarded engineering degrees in management science and engineering, are required to use the first-level examination paper.

Majors participating in the re-examination: two disciplines and majors of five first-level disciplines, such as textile science and engineering, light industry technology and engineering, agricultural engineering, forestry engineering and food science and engineering, require the use of mathematics re-examination papers.
