as a grad student, do you live in dorms with other grad students or do you live with undergrads? living with undergrads would be awful as a law student! if you don't mind me asking, how much does your brother pay for his off-campus rent? I am not familiar with the Gainesville area at all.
I agree about living with undergrads, especially since UF is notorious for being a "party school" I am not really sure off hand about either of your questions. You probably would be better off calling the school and asking them instead of me.
