I know exactly how you feel. Thinking about my answers, up till i got the decision, i wouldnt really change much about any of them. I realize no answer can ever be perfect, but that was as almost about as good as gets. And my ECs are actually great, as judged by friends in med.
On a side note, is anyone here waiting for multiple schools?
I am, but at this point I have this sinking feeling I'm going to get none of them.
