Room and board is generally separate from tuition. The college I went to charged obscene amounts for it's dorms. You could get a studio apartment to yourself twice the size within 15 minutes of campus for about the same price as having to share a tiny dorm room. The on-campus apartments were worse, since the amount the four people sharing an apartment were paying combined would be enough to rent a good sized house nearby with money left over. I'm sure they get enough charging for the rooms that it isn't affecting tuition price.
