OP you are there at the Uni to learn to grow and pass the course+exams. If you need to do extracurricular activities, please setup time at home, travel home to do those things.
If home is faraway and you still want to do it, find a reliable off-campus-non-dorm location and do your stuff from there.
Your main objective is to get through Uni without falling behind and managing your time and effort wisely. If you fail Uni because you focused too much on non-essential activities, be a responsible adult and accept the results of your adult decisions.
Edit: I never said that OP shouldn’t do non-Uni activities. Just that time+effort has to be MANAGED between the two. Life isnt fair and life doesnt give two shits if you fuck up. That is what being an adult means.
Edit2: I can see people commenting on Universities imposing mandatory dorm fees. Do you people not choose which university to apply and get accepted? Did you not think…“this uni is very strict, or this uni has a lot of on-campus resources, or this uni has great course-materials, etc etc” … and it would also include “this uni dorm is optional/mandatory and I can live there cheap or live outside expensive or it is bum-ducking nowhere but fields/forests/wilderness” … you did choose that uni to attend and paid up ?
