It depends if you're going to live on campus. If you are, then you will need these things: toothbrush, shampoo, soap, blankets, pillows, notebooks, pens, pencils, Ethernet cable, some snacks, and probably a subscription to netflix. i mean, it might get boring at night or sometime and you'll need something to do. believe me, i'm on my campus right now and it's only my second semester of my first year.
Do you mean for living on campus? If so, you can probably use most of the same stuff you have at your house- bedding, clothing, school supplies, books & movies. Any hobby that you can bring and that you think you will have time for. Maybe a lamp and a chair depending on what the college supplies. Try to use stuff you already have or second hand stuff so that you won't be spending alot of money.
