Bren update:
I just called Bren's office and it sounds like it will be "a few weeks until they make the decision", my best guess is that I'm on a waitlist. She said that my application is obviously competitive as they've sent out acceptances and rejections. I mentioned that I needed to make a decision at other schools by the 15th, to try to get the woman to narrow down the date when I would hear. Her response is that they're working really hard to meet that deadline. The way Bren has handled admissions so vaguely and elusive is only making me want to go to Duke more. Best of luck to everyone with your application decisions!
