But what do medical schools mean in their secondaries by "Explain gaps in your education." I finished an academic enhancement post-bac program and I'm applying to medical school now. I started my post-bac program right after finishing my undergrad degree, so I guess I didn't really have a 'gap' in my education. Do I explain how I transitioned from a mediocre GPA in undergrad to a 4.0 post-bac GPA for this question or do I address that somewhere else? Thank you!
