I've gathered a bit of information from various sources about the Colleges, and this is what they had to say:
Lincoln: Theres a lot of med/dent students who go there, so that would be good for me or even any HealthScience students. However theres a pecking order, where the older students take the bigger rooms and the freshmans are left with the smaller rooms - and theres a male and female bathroom for a floor of 10 people - sounds cramped
and theres also a lot of International Students
Aquinas: Supposedly when a friend went there for their interview, no one bothered to clean up the rooms they had to stay in. Plus, they found the mattresses provided were all soiled, and they couldn't find any non-soiled mattresses, so they ended up sleeping on the floor because it was so bad - doesn't look too good :S
StAnns: Nice place, except the Dean makes you participate in a lot of the College Activities, which can be a bad thing if you either want to study/do other things.
StMarks: Supposedly a lot of students who come from Rural backgrounds, and the College is really into its sports. But I probably won't apply here because its relatively $$$
Anyway you can tour all of the Colleges there, so I can probably make a final decision there. But that Aquinas thing sounded surprising!
