1. Yunxiuzhai various classes

Lao Zhou's personal feeling system is the best combination. Lao Zhou's class is highly recommended (the common sense in number theory class is very dazzling, and CMO class has analytic number theory)

2. Guo Zi studies CMO class

There is nothing to recommend, but it is not systematic and a bit broken.

3. Nova

In fact, in the first two years of high school, I took classes in Nova three times, twice for nine days, once for 14 days. I feel that Nova's class is not very good, but I still have to go. Nova's class is too watery and not too difficult, but the topic represents the recent wind direction and has to be attended. If you want to go to class, it is recommended to go to class 14 days. Be careful not to bring your mobile phone. It is best for parents to watch.

High level:

Class nine, CMO class of Gauss, CMO class of Yunxiuzhai.

(The senior class in primary school feels worse than the above three classes)

Others are not systematic, just saying what the teacher said: Wang Yongxi and Cao Mao, two great gods, must attend classes. Teacher Tian Kaibin's number theory class is very comfortable and difficult.

If there are different teacher systems in geometry class, it is suggested that both Mr. Zhou Xiaodong and Mr. Cao Xie finish geometry class (their systems are not in conflict).
