Postgraduate entrance examination mathematics 1 examination subjects: equivalent mathematics, linear algebra, probability theory, mathematical statistics. The proportion of each subject is: mathematics 56%, linear algebra 22%, probability theory and mathematical statistics 22%.

Three exam subjects of postgraduate mathematics: calculus, linear algebra, probability theory and mathematical statistics. The proportion of each subject is: mathematics 56%, linear algebra 22%, probability theory and mathematical statistics 22%.

Second, the scope of investigation is different:

In equality mathematics, the main differences between number one and number three are: spatial analytic geometry, multivariate function integral (except double integral), only taking math one; In the physical application of calculus, there is only one math course, examination; The economic application of calculus only takes math three.

In linear algebra, the contents and requirements of the test of number one and number three are almost the same, but the difference is that there are many vector spaces in mathematics, 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.

Third, the degree of difficulty is different:

The investigation scope of No.1 is relatively large, and the requirements are higher than those of No.3. The first question is slightly more difficult than the third question as a whole.
