I was planning on applying to the med school right before starting the MC program. It looks like a lot of the MC students that graduated ended up getting accepted to the UMiss med school. I'm just assuming that they didn't have a gap year, mostly because if you look at the 2010 graduates, it says that they've been accepted to UMiss med. I guess that could still mean they have a gap year, huh?
Either way, there are post baccs/SMPs like the one at Georgetown where people talk about how they didn't have a gap year and they started at a med school other than Georgetown the following year. That means that they interview before the program was over, my guess is sometime around winter break after their first sem grades were released and they were able to get recs. Even if I do have a gap year, it's a lot easier finding a decent job with a MS compared to a BS...
