When I was a freshman, there were quite a lot of classes, public courses and professional basic courses. Generally speaking, there are more classes in the morning and afternoon. The general college entrance examination is full-time, either full-time or night school, correspondence, and others. Generally, there are not many classes in junior year, and there are not many classes in a week. The senior year is mainly internship, and there are basically no classes. But it depends on your major. Now many schools still require self-study in the morning and evening, and choose a few days a week.
