What impressed you positively?
The honesty of the faculty and students.
What are your general comments?
There was a lot of waiting time, but I'm finding that's true with most schools. We(the interviewees) had a group orientation, including financial aid, and an intro to the school. Then I had an interview with a student. Then a long wait. Then lunch, followed by a tour, my second interview, and that's it. They're very friendly and helpful. Bring something to read, and don't worry about bringing your luggage(I stowed mine safely in the office). Great School!
