Oh, I have waves of panic where I feel wholly inadequate and wonder what my recommenders must have written to get me in. (My advisor is an alum, and one of my other writers did some postdoc work there). I mean, I never would have let me in with the statement of purpose I wrote, they didn't want GRE scores, and everyone applying there has grades like mine. I felt like a fake in undergrad - got a lot of attention for very little effort. Maybe I shouldn't have mushed everything into three years to graduate early, and taken the fourth year to really get myself ready for grad school.
Oh, who am I kidding. With all of my requirements done, there's no way in hell I would have done serious work. *sigh*
