In college, you are more free. As long as you attend classes on time, there is no problem going back to the dormitory after class. Don't worry too much about the teacher checking the bed. In college, as long as you attend classes on time, you should listen to the lectures well, read more books at other times and arrange your after-school life. There are few college courses, so you can take part in more activities at ordinary times.

You can do it after self-study at night, but you can't do it at ordinary times. Universities can't go back to the dormitory after class, because under normal circumstances, if there are managers in the dormitory during the day, it is stipulated that all students can't go back to the dormitory from Monday to Friday, and some students sleep in the canteen or play games outside the dormitory, which is convenient for unified management and students can study by themselves.
