Tepper's welcome weekend was good. There were a few icebreakers so you could learn about other admitted students, an international festival where current students showed off skills you'd never know they had, a few sessions (academic, club, career), a dinner at Heinz field, after parties at bars down the block from the hotel. It was nice.
I'm still undecided. Emory's welcome weekend really blew me away and CMU's didn't, but there's no denying that for trading, it's significantly easier to get a good job out of CMU. I actually decided during this weekend to apply to the MSCF program as a dual degree, and if I get into that, I think I'll go to CMU. Otherwise, I'm pretty content going to Emory and rounding out some of the leadership and management skills that I don't have much experience with.
Anyway, at this point, I'm still undecided. I'll know soon enough.
