I don't intend for this to be a downer, just a heads up. I spoke with Dean Shields recently and he said that Duke has admitted a ton of people this year, and it didn't look like they were going to dip too far into the waitlist this year. They really won't know until after May 1st, but it sounded like a lot of people have already sent in deposits and the class is going to fill up from regular admits.
Doesn't sound good for those of us holding out hope.
Question: Were you able to get in touch w/ Dean Shields pretty easily? Was he polite about talking to you? I talked to some admin assistant in the admissions office who wasn't helpful at all, but I was a little intimidated to ask for the big man himself. However, I think he would be a lot more forthcoming with information, especially as the summer goes on.
