First of all, the proportion of the three mathematics courses is different: the number of high school students accounts for 60%, while the line generation and generalization account for 20% respectively; Calculus of number three accounts for 50%, line generation and generalization account for 25% respectively; Secondly, the biggest difference between number three and number one and number two is that number one and number two are science and engineering, and they have higher requirements for high numbers. Economics, especially the number three, has very high requirements for linear algebra, probability and mathematical statistics, which is higher than our science and engineering courses. Accordingly, the content of the number three exam is different, and the specific content difference can be seen in the annual exam outline.

Emphasize that the review materials for calculating one and calculating three must not be the same.
