There are a lot of things that you don't need to bring to college, and you don't NEED everything on this list, but there are some things that you might overlook as you shop for college. I've added some of them to the list.
A piece of fabric to cover the nasty fluorescent light that's probably in the middle of your room. Maybe wait to buy this until you see the room.
Some sort of lighting to use when you don't want to use that horrific fluorescent light in your room.
Shower shoes. Don't shower barefoot. Unless you're comfortable with that. But I couldn't stand to do that.
Two sets of towels. I had my shower towel fall on the bathroom floor a few times. I would then put it in the dirty clothes and use my second towel.
Some entertainment reading. Not a ton, and it depends on who you are, but it's nice to have once in a while when you've got some down time.
Different levels of clothing. By this I mean, have your workout clothes for your intramural games, but also have some nice clothes for interviews or something of the sort.
Ethernet cord. The wi-fi at college can suck. I had an Ethernet cord and it seemed to me that I had better internet than most.
Some extra supplies (especially if you don't have a car, then you can go longer between store runs). If you don't have the space for it, then you can make do. I did enjoy having the extra stuff though.
Thank you notes and/or blank cards. I went through a ton of thank you notes. Not everyone writes them, but I try. I also used blank cards to write my friends little notes.
Stationary. It's fun to mail snail mail on pretty stationary. This isn't something that you NEED, and it probably shouldn't be on this list, but it doesn't take up much space, and I liked having it.
A fan. Of course it depends on where you go, but I don't know how I would have survived without my fan. It was only useful in September and May, but it was run 24/7 in those few weeks.
Painters' tape. It's usually blue. Of course, it depends on your college, but you're probably allowed to use this tape. I also had duct tape that I used every so often for random things like making the outlet strip stay attached to the fridge and out of the way.
Outlet expanders. I had so many. There were five outlets in our room, and we had expanders on four of them. I had a phone charger, a kindle charger, a lamp, an alarm clock, an electric toothbrush, a Clarisonic, a fan, a microwave, a fridge, and a computer (I think that's it.) So I had to have lots of outlets. Also, there's the roommate to consider, because he or she probably has around the same amount of things.
An iron can be useful too. It's not necessary, but I found it useful to iron a few dress shirts, and to iron my graduation gown. It wasn't too hard to store, and you don't need an ironing board, you can just use a towel to iron on. However, I have seen some college laundry rooms with irons and ironing boards.
A drying rack. I used mine every single wash load. I needed two usually so I borrowed a friend's or a neighbor's. Most of my clothes can't be dried in the drier though, and I had friends who got along without one. But about 90% of my clothes have to be air dried so it's necessary for me.

There may be other things that are necessary for college that I'm forgetting. I'll try to add them as I think of them. Is there anything else that you can think of that's necessary?
