Yes . . Each subject has a "layered assignment". This is the homework assigned by the school itself. There are "champions" in Chinese and mathematics. There are famous teachers to accompany you and English newspapers (similar to junior high school). Biology also needs to be "optimized". Some classes want to be "Su Da" in mathematics, and physics is a must. (Su Da refers to the materials published by Suzhou University Press) It seems that this is all. Of course, like math English, there will be some homework in the book, which is necessary.
