I know it's much, much easier said than done but be patient guys. They got over 8500 apps last year. Imagine having to go through a bulk of those apps all at once, combing through what makes each person unique.
Unfortunately, it's not exactly a linear process and I don't know the algorithm. It's very well possible that someone could have submitted after you but scored higher and are subsequently thrown in the next immediate batch of IIs. That doesn't mean you didn't score well in the grand scheme of things but realistically there's always going to be automatons or even all-around rockstars that will squeak their way in and bump otherwise pretty solid students a bit further down the line.
Give it time. As we move further into the fall, I suspect more of the solid students and applicants with a compelling story, will see their day. Interviews only started this month. Keep your heads up!
Also, reminder for those interested in the MD/MPH, please feel free to tag me in a post so I leave a reply on the board for others as well.
