I have always liked Xiaojin coming uninvited. His classes are concise and interesting. However, after listening to Schell's comprehensive class, whether it's jxs or gjn, I just want to say that I really can't meet my personal needs, so I'd better not stay in Dongao. Specifically, all comprehensive courses are passed in six subjects, and there will be no bad candidates. Please don't talk about something very basic just to show how valuable your course is (it can be said that it is chatter), which wastes time and makes people lose focus. Synthesis is the key. Teacher Xiao Guo talked about a factor analysis for a long time, which made people unbearable. Let's go back to the previous lecture style!
