Medium level. Mathematics is relatively simple in postgraduate mathematics, so 120 is not a high score, but only a medium level. Advanced mathematics and linear algebra are tested in the second entrance examination for mathematics. Advanced mathematics includes function, limit, continuity, differential calculus of univariate function, integral calculus of univariate function, differential calculus of multivariate function and ordinary differential equation. Linear algebra includes determinant, matrix, vector, linear equations, eigenvalues and eigenvectors of matrix, and quadratic form.
