I know that they aren't exactly outstanding stats for Harvard's standards, but I wrote them a letter when I was placed on the waitlist, and I'm thinking that it was the letter that put me over the top. Something definitely worked in my favor! I'm surprised, because when I called them last week, they told me that they wouldn't even start reviewing the waitlist for another few weeks at least. I guess we can't really rely on what the admissions office tells us.
Oh, and thanks!!!!!
