Duplexes don't have a washer or dryer, you supply em, and you'll need furniture,so it can get costly; the dorms are easier but I lived in a duplex and the money spent on appliances and furniture was worth it. You'll also need to find a roommate within one class of yours, if you dont show up at housing with a roommate, you'll be put in a dorm, they won't spend their time finding you a roommate.
