I'm also waiting and trying to pump out more secondaries. I am getting very discouraged. I have also have a mediocre MCAT score (32Q) compared to all of the superstars. I am so close to just stopping now and reapplying next summer...EARLY. I come from a public university with no medical school. Not much people here know about applying to MD/PhD programs, so I didn't realize how imperative it is to apply early. It is difficult at this point to watch everybody else on this thread roll in inteview invites. It feels like all that I have worked toward is slipping through my fingers. So, I am right there with you...waiting. There are probably more of us just watching SDN behind the scenes, so I agree with ZenAlchemy...it is not good for us to keep looking at SDN. It destroys confidence. I also do not listen to my own advice.
By the way...at this point, are you guys writing completely new research experience essays and "why MD/PhD" essays for the secondaries? I know the people who applied early did, but it is probably better just to submit the secondaries as soon as possible.
