I am a non-traditional student with a bachelors and a cumulative GPA of 2.7. I started to do a DIY post-bacc and I have completed all the Med School pre-reqs, including Biochem, but not the recommended extras like Genetics and Microbiology. For the post-bacc I have completed 32 credits hours with a 3.9 GPA, that brings my cumulative GPA to 2.90. To bring that up to 3.0 for the 2021 application cycle I would need to take 14 credit during the fall and 14 credits during the spring. I do have a full time job that I cannot quit until I get accepted into Medical school, that means if I take 14 credits per semester that would leave very little time to study for the MCAT.
My question: what would be a better use of my limited free time, take fewer credits per semester and study for the MCAT, potentially getting a higher score and apply to medical school with a 2.9ish GPA or aim for the 3.0 GPA and a potentially lower MCAT score?
