I'm currently 29 yrs old and preparing my journey into med school. I have an undergrad degree in Biology and my goal is to use the next 1-2 years gaining experience, volunteering, and re-taking courses. I received C/D in OrgI/OrgII and a C in Phy II. I want to better these grades, possibly taking the rest of the pre-reqs as well to prepare for the MCAT. Is a post-bacc the best route? What about an SMP? I have yet to take the MCAT.
