According to different schools, each school is different. Generally, universities will have evening self-study, which is an adaptation period for freshmen. Self-study in the morning is generally the result of discussion in class. Most schools don't have hard and fast rules, but morning and evening self-study is only available for freshmen, but not for sophomores. In order to save those students who are caught between learning and not learning. If you don't study at night, you may be dragged to play games by your roommates.

Top student may not be willing to concentrate on his studies in the designated place, but he still studies hard.

As for salted fish, just continue to play mobile phones or skip somewhere else. It is nothing more than the self-comfort of the management. I'm not sure about other schools. Just tell me about me. I majored in electronic information. When I was a freshman, I had to study sooner or later. Self-study begins at 7: 00 in the morning and begins at 7: 00 in the evening, because for freshmen, I think most of them study in the morning and evening to prepare for Band 4. The sooner the university finishes CET-4 and CET-6, it can save a lot of energy and time. I've also heard that one of my art students said that this major doesn't need to study at night. Personally, we stopped studying in the morning and evening after our sophomore year.
