Same... I found scrap of paper recently that I used to jot down notes during my interview that says "decision in 4-6 weeks, look out for email mid-late April." It's been twice that long for me and I know others waited way longer haha.
No joke, I had one more interview after my Drexel interview, was waitlisted at that school, and then got off that waitlist, all in about 7 weeks. Granted Drexel has a bigger class than this other school, but still. I think this kind of thing affects the makeup of the class they end up with. Anyone still in the running is clearly more than qualified to attend med school, but people with multiple options at this point are gonna start to say screw it and withdraw. Maybe that's what Drexel wants, but personally I think they're shooting themselves in the foot.
