There are key classes in arts and sciences. There are two key classes, 1 class is the best, followed by class 2. Others are ordinary classes. Then if I don't do well in the key class, I will be kicked out, and then the students in the parallel class can apply for admission, according to the results of the big exam.
It is not clear how many people are ranked. However, according to the number of people admitted, only a fixed number of people are admitted, and the school publicly draws lots to decide the reference places.
