Stuff to organize your room.
Depending on how large it is, and what's already part of the room...
Shelf organizers, closet organizers, bookshelf, tupperware containers, separate shelving units, etc.
Also, a microwave if you can have one in your room (i had one even though we weren't supposed to //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif), power strips so you can plug in multiple things from one outlet.
Also, don't forget silverware, dishes, pots and pans, and the like. Basically stuff to cook things in.
I'll probably think of more stuff later as I remember what I wish I had my first week of college. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
