I was wondering if any one else was going to be there! 
Quick question(s): What should I expect? Do I have to bring anything?
IIRC from when I went last year you don’t have to bring anything. It is more or less a glorified normal tour. There will probably be some panels where they bring up high (over) achieving students, some faculty, and make everyone uncomfortably dance around to Varsity or Jump Around. Have fun, maybe try to meet someone, and see if the campus is the right fit.
