I feel for you guys. When I applied last cycle, I applied to around a dozen places.
LizzyM~74, applied to 12 places, got 2 II's, and no cigar on either. This cycle I applied to around two dozen places and got 9 II's, and I've been fortunate enough to have been offered an acceptance really early on. So I have a couple of questions for you guys that I think could hopefully shed some light on you guys' situation.
1) When did you guys submit your secondaries? Submitting secondaries early can give you a strong edge, especially if you're a solid but unexciting applicant. When schools have more interviews to give, they tend to be more generous with them to whomever is applying.
2) How are your guys' clinical experiences? Clinical EC's are generally the most significant EC's given the obvious fact that you're trying to go into a clinical profession. Medical schools want to make sure that you guys know what you're getting into. They're more worried that you'll drop out because you realize you don't like medicine than because you couldn't handle the coursework. Shadowing is extremely important. It's crucial to have relevant shadowing experiences that have helped confirm your desire to become a physician. In my opinion, family medicine is probably the most important specialty to shadow since it captures many of the essential features of the profession (patient-physician relationships, holistic approaches towards care, being prepared for anything etc.). A lot of people spend a lot of time shadowing various specialists, which is cool, but may offer one a very limited view of what the profession is.
