I'm visiting this week. What are some things I need to see?
If you're here Wednesday night, i would suggest going to the basketball game to get a feel on the school spirit and environment that the Convo brings to campus (plus, if you do decide to go here, students go to all sporting events (minus hockey) for free!)
If you're here any other day, I would take a visit to court street during the day to check out the shops and places to eat. Your tour guide will take you to all of the important on-campus sites, so there isn't a whole lot that you won't see on campus.
Also, if you haven't already, try arranging a meeting with whoever is the head of your department that you are applying for. You can ask a lot more specific questions about the major there and get a feeling on what you can do to get prepared to go to school.
