Although the contents of Math I and Math III are all advanced mathematics, linear algebra, probability theory and mathematical statistics, accounting for 56%, 22% and 22% respectively, the emphasis and some knowledge points to be mastered are different, which also causes some difficulty differences between Math I and Math III.

The examination of number one focuses on infinite series, curve and surface integral, which is compulsory every year and is often examined in the form of problem solving; The number three requires mastering the problem of economic application, which is basically required every year. 20 15 examines the marginal cost and elasticity in the form of solving problems, 20 14 examines the marginal income in the form of filling in the blanks, and 20 13 examines the marginal profit in the form of solving problems.

In addition to the different key knowledge, some knowledge points that need to be mastered are also different.

In advanced mathematics, mathematics one examines the physical application of spatial analytic geometry, multivariate function integral (except double integral) and calculus, while number three does not; The number three examines the economic application of calculus, while the number one does not.

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.
