Since 2009, the national unified entrance examination papers have changed from four to three, namely, No.1, No.2 and No.3.. According to the regulations of the examination center of the Ministry of Education on the classification and use of mathematics test papers, engineering students should take math I and II, and economics and management students should take math III.

First, the difference between different majors

1. Students must use the enrollment requirements of Math I or Math II: two disciplines, namely, material science and engineering, chemical engineering and technology, geological resources and geological engineering, mining engineering, oil and gas engineering, environmental science and engineering, which have higher requirements for mathematics, are selected as majors.

2. The enrollment major of Math II must use all two disciplines and majors in five first-level disciplines, including textile science and engineering, light industry technology and engineering, agricultural engineering, forestry engineering and food science and engineering.

3. The enrollment major of Mathematics III must use: the first-level discipline of economics, the first-level discipline of management, business administration and agricultural and forestry economic management, and the first-level discipline of management science and engineering with a management degree.

Candidates' majors need to be tested in mathematics, which is determined according to the above professional divisions. If the above division is not completely determined, you can check it on the admissions website of the colleges you apply for.

Second, the examination scope of mathematics

1, Math 1

① Advanced mathematics (function, limit, continuity, calculus of univariate function, vector algebra and spatial analytic geometry, calculus of multivariate function, infinite series, ordinary differential equation).

② Linear algebra (determinant, matrix, vector, linear equations, eigenvalues and eigenvectors of matrix, quadratic form).

③ 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).

2. Mathematics II

(1) advanced mathematics (function, limit, continuity, calculus of one variable function, ordinary differential equation).

② Linear algebra (determinant, matrix, vector, linear equations, eigenvalues and eigenvectors of matrix).

3. Mathematics III

① Calculus (function, limit, continuity, one-variable function calculus, multivariate function calculus, infinite series, ordinary differential equation, difference equation).

② Linear algebra (determinant, matrix, vector, linear equations, eigenvalues and eigenvectors of matrix, quadratic form).

③ Probability theory and mathematical statistics (random events and probability, random variables and their probability distribution, joint probability distribution of random variables, numerical characteristics of random variables, law of large numbers and central limit theorem, basic concepts of mathematical statistics, parameter estimation and hypothesis testing).

Third, the difficulty is different.

The biggest difference among the three types of mathematics papers lies in the requirements for knowledge: mathematics 1 is the widest, mathematics is the third, and mathematics is the lowest.
