According to the different requirements of various disciplines and majors on the mathematical knowledge and ability that graduate students should have when entering the postgraduate entrance examination, there are three kinds of postgraduate entrance examination papers: one is engineering, the other is mathematics; For economic management, it is Mathematics III (before 2009, it was Mathematics III for management and Mathematics IV for economy, and after 2009, the syllabus merged Mathematics III and Mathematics IV). There are specific regulations on the types of test papers used by different majors.

1, the examination subjects are different.

The examination subjects of Mathematics 1 are: advanced mathematics, linear algebra, probability theory and mathematical statistics.

Kobe focuses on: advanced mathematics? 56%? , linear algebra? 22%? Probability theory and mathematical statistics? 22%? .

The examination subjects of Math II for postgraduate entrance examination are: Advanced Mathematics and Linear Algebra.

In the test questions, the weight of each Kobe is: advanced mathematics 78%, linear algebra 22%.

The three subjects of postgraduate entrance examination are calculus, linear algebra, probability theory and mathematical statistics.

2. The content of the exam is different.

The difference between the test contents of No.1, No.2 and No.3 is mainly reflected in the test scope, in which the test scope of No.1 is relatively wide and that of No.2 is relatively narrow.

Specifically, in higher mathematics, the main differences between number one, number two and number three are: spatial analytic geometry and multivariate function integral (except double integral), only mathematics one is tested; Infinite series, only take math one and math three; The physical application of calculus only tests Math I and Math II; The economic application of calculus only takes math three.

In linear algebra, the examination contents and requirements of number one, number two and number three are almost the same, but the difference is that there are many vector spaces in mathematics one, which are rarely involved, and have no substantial influence on the candidates' review.

In probability theory and mathematical statistics, the scope of investigation of Math 1 is slightly larger than Math 3, which mainly increases the test sites for parameter estimation, including the selection criteria of estimators, interval estimation and subsequent hypothesis testing.
