currently the minimun entry requirement for undergrads are about B, so pretty much they receive preference than graduate students, i heard. Beside living in residence is a lot expensive than off campus, i have been in some of the res, rooms are so small, shared kitchen with entire floor of people. Unless you apply for Brooks, which is pretty much impossible to get one unless your are taking over someobe else's lease.why don;t you try to come to Ottawa early and find yourself a room off campus? you will find it a lot convenient and cheaper.
