For example, there are more than 200 undergraduates in our major, so there are both large classes with more than 200 students and middle classes with 40 to 50 students. A few majors also have courses for more than a dozen or even two or three people.

The weekly class hours also vary according to the situation. When we were undergraduates, if we didn't have a double degree or minor, it usually took about 20 hours a week, at most 25 hours a week. One class every hour. There are also some schools that have no maximum credit limit for choosing courses each semester, and the weekly class time will exceed 25 hours.
