congrats for the interview offer from columbia. u r in a better shape than i am. =) mine is on march 8, that was the earliest available. well i just hope the class is not close to full.. although it probably is getting close to full as i'm typing. anyways, i work in a building next to a dental school... maybe if u r thinking about sticking around the school after the interview, we could get together to chat. just an idea.
good luck with ur interviews and keep me posted.
as for me, i have nyu interview next week, and one at columbia in march. anyways take care
