Of course. In college, time is relatively free, basically at your own disposal. However, some students will use weekends to go out to play and go home to visit relatives. So they can't go back to the dormitory to sleep. Most universities do not require students to go back to their dormitories on weekends. However, some schools have strict management of students. When there are clear requirements, you must abide by them, otherwise you will be punished for violating the rules.
