Postgraduates applying for mathematics (such as applied mathematics, computational mathematics, basic mathematics, operational research, etc.). ) Because mathematics is a specialized course rather than a public course, the graduate students enrolled in various schools are all engineering, physics and chemistry, computer, finance and economics (general propositions are mathematical analysis, advanced algebra, ordinary differential equations, probability statistics, etc. Or like Tsinghua of Peking University will combine mathematical analysis, differential equation, real variable function and complex variable function on a test paper). Because advanced mathematics is a public course rather than a specialized course, the proposition is unified by the state. According to different types, it is divided into high number 1, high number 2 and high number 3. General high number 1 is the high number of national unified proposition, which is aimed at physics and computer graduate students who have higher requirements for calculus, including calculus, linear algebra and probability statistics. The proportion of each part of the three sets of papers is different.
