The first test of mathematics for postgraduate entrance examination is the most comprehensive and difficult, the second test of mathematics is the least, and the third test of mathematics is the most comprehensive, but the difficulty is not as difficult as mathematics.
Counting one is the hardest. Count three times, and count twice is relatively the easiest.
Mathematics 1: the score of advanced mathematics accounts for about 60%, while linear algebra, probability theory and mathematical statistics each account for about 20%. Math II, advanced math scores account for about 80%, and linear algebra accounts for about 20%. Mathematics III, advanced mathematics scores account for about 60%, linear algebra, probability theory and mathematical statistics account for about 20%.
Math 1: Examination content: advanced mathematics (function, limit, continuity, calculus of unary function, vector algebra and spatial analytic geometry, calculus of multivariate function, infinite series, ordinary differential equation);
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).
Math 2: Exam content: advanced mathematics (function, limit, calculus of one variable function, ordinary differential equation);
Linear algebra (matrix, matrix, vector, linear equations, eigenvalue and eigenvector of matrix).
Math 3 is almost the same as Math 1.
