At my school, the returning students (non-freshmen) move in the day before classes start, which usually falls on a Sunday. Note that this only applies for students who live on campus only. You can move in anytime if you live in an apartment or house off campus.
I was just wondering why some schools do this. I mean, if everyone moved back during the week before classes, then this would give everyone time to join clubs/organizations and meet new friends during the weekend.
Overall, this would be good for everyone because when you move in the day before classes start, you have to unpack and organize your room all in one day. You also have to get ready for classes the very next day. Why not move in early and have an entire weekend of freedom before school starts?
