Since you posted this awhile ago, you have probably received your registration packet, and you'll know what classes you're taking. As far as the required classes, I only know of one specifically, and that is Critical Encounters, which you may already know by now. We have to take that first semester. I know there's more for later years, but I'm not sure what they are yet.
And I haven't seen Andrews Hall in person, but there are some lovely pictures on facebook,

It's supposed to be really nice, but I've also heard the nearest dining hall sucks.
I hope I helped a little!
