Thanks guys, I really appreciate your help. I'm only an average candidate, 2280 SAT, 4.0 GPA, not really outstanding ECs... So I'm just overjoyed that I haven't been automatically thrown in the reject pile like I thought I would be! Getting into Harvard would be such a dream for me, but I don't want to get my hopes up.
Anyway, my interview has been scheduled for this Monday, and and if you guys want I'll let you know how it goes!
