I called Duke today to question the status of my application, and they informed me that they're going through applicants alphabetically (I was a 'T' at the time of application, before my marriage), but they hope to be finished in the next 2 weeks. Hopefully that will ease some minds!
I haven't heard anything either way yet, either. I'm freaking out. If potential students' weekend is in less than 2 weeks like some of you have said, I feel like I'd have to know by now--yet I'm not in the wave of rejections. I hope that means I'm on a waiting list..
