Read pages and pages of medical ethics info from the web. Read over my personal statement. Didn't stress about it.
What impressed you positively?
The faculty and students I met were very friendly. Some of the presentations could have been really boring, but the speakers were quite humorous and inviting. The clinical skills lab is really cool...and it's run by one of the funniest ladies I've ever encountered. The integrated curriculum is a great concept.
What impressed you negatively?
No wireless hotspots in the Medical Sciences Building...so think twice about that new iPaq PDA with integrated WLAN. Maybe in the future, though.
What did you wish you had known ahead of time?
Nothing, really. I knew more about the place from working on the Med campus than I learned on my interview day...but I expected that. I think the people from out of town were positively impressed, but I can't say for certain.
