You need to take at least 2 courses each semester, and one semester lasts for 4 months. You can apply for graduation by taking 12 courses!
Generally, a course lasts 2-3 hours.
If you take two classes in one semester, that is to say, you take classes twice a week and rest on Sunday, and the class time is from Monday to Friday (see class time! )
Of course, there must be at least five students in a course. If five students don't sign up, the course will be over!
