The things I remember from college:
Laundry - especially the guys. And ironing. There were a couple of times, guy friends would show up with a nice shirt they needed ironed because 1. parents were coming to town and they had to go to a. dinner b. church, 2. meeting with a professor/scholarship awards 3. a date.
Cleaning up your clutter in the common areas. In one of the dorms I lived in, there were 4 double rooms, a common living room and a common bathroom. A janitor would come in and vacuum, empty trash, and clean the bathroom, but if someone's junk is laying around.
Estimating how long the money on your food card will last.
Just go ahead and tell your parents when you are leaving town, even if they are going to be unhappy about it. We had one girl who went to a different state for a long weekend and didn't tell them. Her parents kept calling, and when they got no answer they called the campus police who came knocking. Don't put your roommates in the position to have to rat you out. On the same note, if you have an out-of-state fiance don't ask your roommates to lie to him because you want to get it on with the cute guy in your math class.
Money issues of all types. Sophomore year, I roomed with a friend. But she had been raised to not have to think about money. When I called to setup the phone, we were going to use her number from the previous year. The service agent told me that she still had several unpaid bills, and it would be in my best interest to put the phone in my name only. Which is what I did. I would have to wait a couple weeks after the bill to get her portion, but I always did.
The second issue with her, I didn't find out until after the year ended and we were living on our own. She came to lunch, very upset one day about dealing with her bank. She thought that "overdraft protection" meant that the bank would cover her overdrafts with no cost to her. And now they wanted her to pay fees AND the money that she spent that she didn't have in her account in the first place.

And since I kept my same phone number, for the next two years I had to deal with her bank and collections calling me looking for her.
