Teacher Wu Zhongxiang was recommended by Shu Gao, and teacher Zhang Yu was recommended by linear generation and probability theory. Teacher Wu Zhongxiang's explanation of high numbers is really simple and clear. There are many dry goods, especially the volume of double integral. One formula can solve all problems. In the part of line generation and probability theory, teacher Zhang Yu explained humorously, which can quickly understand the essence of knowledge points and quickly master the method of doing problems.

Suggestions for the students' pre-review are: Wu Zhongxiang takes the book review to improve the chapters, Zhang Yu takes the basic 30 lectures and strengthens 36 lectures. Pay attention to reviewing the basic articles of the book. Don't buy them. Buy improved articles directly. The basic articles are incomplete. It is most cost-effective to buy improvement articles directly. I followed Mr. Wu Zhongxiang all the way to Gaoshu, which is highly recommended. Of course, Brother Yu spoke very well, but because I didn't have enough time, Brother Yu didn't finish too many classes. If you like humorous lectures and have enough time, you can follow Brother Yu from high school.
