I'm a first year student, and it's a "post-bacc" (Master's) program with one of the highest success rates in getting students into MD programs for a reason. Acceptance into the MD program is *no guarantee,* though; it must be earned. It's competitive to gain acceptance to and rigorous once accepted. If you're willing to grind your butt off, you have a shot of getting in. The best part about this program is we take the same classes MD students take but a slower pace. They're taught by the same professors with very similar exams. If you can get into this program, your foot is well in the door. It's a matter of *getting in.* Also, MSMS students who apply for MD receive special consideration, so there are seats open for MSMS students. The competition is fierce, though.
For most, the MCAT is a stumbling block, but first semester taught us skills to tackle it. Very few gain acceptance after one year because most need more time preparing for the MCAT, but it's possible (just unlikely). After a semester, I was one of several who re-took my MCAT in January and was one of few--if not the only one--who received an MD interview invite. My classmates knew me as someone who worked tirelessly, which proves it's possible with grinding.
