I'm not sure if sending a letter will help, but they told me they'll put anything I mail in my file, so it would definately show interest (since you should only send one letter of interest to your top school, since I hear schools talk to one another?).
I think they pull people off their hold list periodically until the end of March, probably as spaces open up in the class and as they finish interviewing more applicants. At that point, you're either accepted, rejected, or put on the wait list (which is different from the hold list). Dartmouth has a similar process, except they don't tell you you're application is being re-reviewed until the final decision is made around March.
hehe, thanks! Good luck to you!!
i would like to know how many ppl they pull of the hold list too.........do you think sending a letter would help??? do they wait until like may to pull ppl off or do they just do it anytime? AHHHHHHHHHHHH, i know how you feel h! hang in there buddy
