Third: 50% calculus, 25% linear replacement and popularization.

One of the exam subjects for postgraduate entrance examination is: advanced mathematics, linear algebra, probability theory and mathematical statistics. The proportion of each subject is: advanced mathematics 56%, linear algebra 22%, probability theory and mathematical statistics 22%.

Advanced Mathematics and Linear Algebra are the subjects of the second exam of Mathematics for Postgraduate Entrance Examination. In the test questions, the weight of each Kobe is: advanced mathematics 78%, linear algebra 22%.

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

From the above comparison, it is not difficult to see that the biggest difference between No.1, No.2 and No.3 is that No.2 lacks probability theory and mathematical statistics, while No.1 and No.3 are the same in terms of examination subjects and scores.

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 test contents and requirements of number one, number two and number three are almost the same. The only difference is that there are many vector spaces in number one of mathematics, which are rarely involved, and have no substantial influence on 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.

Except for the different scope of examination, the requirements for specific test sites on No.1, No.2 and No.3 are basically the same in all the examination parts. At the same time, because the examination range of Math II in advanced mathematics is small, and the examination score is the largest, this leads to a more detailed, comprehensive and flexible examination of Math II in advanced mathematics. But on the whole, the difference between the number one, the number two and the number three in the requirements of * * * having test sites is not obvious, so there is no need to distinguish them.
