One major is in one class, and then each major has a large number of people, and each major is divided into several shifts. Generally speaking, some criteria for resettlement are randomly divided. Some schools offer joint exams, and then divide classes according to the results of the joint exams. Generally speaking, a class has the same class because of the same major, which is more convenient for the distribution of courses.

At present, most colleges and universities are divided into classes in this way. Some specialized courses are many, while others are few. Some schools enroll students by major category, with the first year randomly divided by number of students and the second year by major.
