Generally speaking, the national line of the initial mathematics test is between 60 and 70, and the specific score should be determined according to the actual situation of the candidates every year.
Take 2020 as an example. In the national examination of mathematics line, 74 points will be scored in management area A, 72 points in economics, 60 points in science and 56 points in engineering.
In addition, in 2022, for example, the national line of postgraduate mathematics, 78 points for economics in area A, 59 points for science and 57 points for engineering; The score of economics in area B is 74, and the score of science is 54.
Because the actual situation of candidates is different every year, the scores will be different every year. Generally speaking, if the candidate's score is about 60 points, it is more likely to pass the national line.
It should be noted that the national line of the initial math test includes not only math scores, but also scores of other subjects. If the results of other subjects are not satisfactory, it will also affect whether the final national line is passed.
The number one postgraduate entrance examination scope:
1, linear algebra is one of the basic parts of mathematics, which mainly studies the concepts of vector space, linear transformation and matrix. In the number one exam, linear algebra requires candidates to master the basic properties of vectors, such as linear combination, linear correlation, linear independence, etc., understand the operation of matrices and the concept of inverse matrices, and master the properties and applications of eigenvalues and eigenvectors.
2. The part of nonlinear algebra mainly involves the knowledge points such as eigenvalues, eigenvectors and quadratic forms of matrices. This part requires candidates to understand the solution of nonlinear equations, master the decomposition and simplification methods of matrices, and understand some special matrix types and properties.
3. The probability theory part is one of the important contents of the top-ranked exam. This part requires candidates to understand the basic concepts of random events, probability and random variables, grasp the concepts and properties of probability distribution and probability density function, and understand the basic theorems in probability theory such as the law of large numbers and the central limit theorem.
4. Statistics mainly focuses on the basic concepts of mathematical statistics, parameter estimation and hypothesis testing. This part requires candidates to understand the calculation methods of sample mean, variance and covariance, master the principles and methods of regression analysis and experimental design, and understand the basic principles and applications of hypothesis testing.
5. Numerical analysis involves knowledge points such as calculus, infinite series and ordinary differential equations. This part requires candidates to understand the basic principles and methods of numerical calculation, master some commonly used numerical algorithms and skills, such as iterative method, interpolation method, numerical integration, etc., and understand the application and operation of some mathematical software.
