Is Handan Jinyu Middle School divided into classes?

There are about 60 students in a class in Handan No.11 Middle School. No.11 Middle School has a west campus and an east campus. My son was admitted to both campuses, but he chose the east campus. There is also a name called Jinyu Middle School in the East Campus. There are more than 30 classes in a grade, which are divided into key classes, experimental classes and ordinary classes. There are generally about 60 students in each class. My son is in class 15, which belongs to the experimental class. There are 68 students in the class.
