I would also recommend some alcohol, if you can get it.
And a fake ID, if you can get it.
But you can get both of the above once you arrive, as well.
Seriously: QUARTERS. I cannot say that enough, and even though it’s been mentioned I’d like to say it again, because invariably you will use your laundry quarters for snacks and run out. Get like $20 in quarters. If you have a shot glass, bring that. If you have a car, bring that. Don’t let anyone tell you you won’t need it or whatever, because it will be worth it to have transportation – whether it’s for a road trip, or getting around town, or heading away for good food when the dorm serves noodles al glop.
Shower shoes are great if you go to college in a warm-weather clime, because they can be used for showering AND walking to class (at least they can at UCLA where I am taking, er sleeping through classes).
Also, take a pocketknife and a flashlight.
Feel free to disregard my alcohol-related suggestions if you are underage (which we all know you aren’t, ha ha), or don’t want to drink, BTW.
