Dormitories will affect grades, because several people living in dorms think they are from different places, with different academic qualifications and different upbringing, so everyone is different. Achievement is the most important thing for a school, and it is also the most important thing for students. Good grades are definitely not just 45 minutes in class. Most of the time after class needs to be summarized, consolidated and reviewed, and some of them are in the dormitory. If a dormitory with a bad learning atmosphere is fun and slapstick every day, then some students want to study hard and will definitely not learn well. The environment will affect them and there will be interpersonal relationships. If one student learns well and others don't, then other students will isolate the student. Good dormitories are tyrants, and they will be admitted to graduate schools collectively. Bad dorms are scum, adventure island.
