I got waitlisted too! I was SO surprised...there are other schools I didn't get into that don't have near the reputation that Columbia does for it's program. So I'm a little confused, but I'll take it...
I have not heard back yet, but I remember the email saying that decisions are typically sent out in mid-February. So, crossing my fingers that it's soon! I also applied to UNC Chapel Hill, NC State, University of Tennessee, and UT Austin.
