I did that on a TAA even though I was GATE, NMS, and had a perfect math SAT I 800.# It loses dorm life and social aspects, doesn't save much money, it messes up course scheduling, and there can be an impedance mismatch in terms of course content/prerequisites. I would recommend against it if at all possible.
# 4-5 years of Boston snow or flambéing in Pasadena didn't seem appealing.
