if there's no kitchen...microwave/fridge...
if there is a kitchen, use that instead.
on the topic of kitchens...
-cooking supplies (pots, utensils, etc)
-plates/bowls/etc
-microwaveable tuperware-type storage containers
Forget the TV & use a tuner card...better yet, don't watch so much TV and go do something social.
-Computer/speakers/printer(?)
-trashcan (even if school provides, a 2nd one is nice)
-shower shoes/caddy; soap, shampoo, towels, etc
-desklamp, floor lamp (iffy)
-some tools
-textbooks (if you took any advanced classes in HS, you'll want'em for reference)
-some food--cereal, candy, canned foods/ramen, etc...just some stuff to have around so you won't have to worry about food initially
-laundry stuff (basket/hamper, detergent, fabric softener, COINS)
-bottled water
-medicines--vitamens, headache pills, allergy pills, etc
-personal ID--passport, SScard, etc
-paper (white & ruled)
-notebooks and/or binders
-ALARM CLOCK
-extra surge protectors
-extension cord(s)
edit:
-phone card (if no cell phone)
-phone (if one isnt provided)
-bedsheets (2 sets), mattress pad
-plenty of clothes...I brought ~2weeks worth of winter AND summer stuff...so I could put off laundry as long as possible
-umbrella
-(maybe) formalwear--dress shoes, shirt, etc (gonna do any interviews/formal events...you don't want to be caught w/o this stuff like me)
-PILLOWS, blankets
-water filter/pitcher (tap water tastes & smells like chlorine here...so this is a must for me)
-more tools if school allows room modifications (like lofting your bed or installing custom shelves)
