Wen Hai's high number was taught by Li Zhengyuan and others, and the probability was taught by Wang Shian, the former head of the national proposition group.

Last year, I sprinted the mathematics of Time, a counseling institution, and I felt good.

Chen Wendeng teaches at Wendeng School. He is the founder and president of Wendeng Group.

Last summer, I intensively reported Wendeng's mathematics. It feels good, but it pays too much attention to skills. Basically, every question has a fixed way of playing. After the postgraduate entrance examination in 2009, I think this method is becoming more and more unsuitable. Postgraduate mathematics pays more and more attention to the understanding of basic knowledge and basic concepts.

I suggest you sign up for Wenhai.
