For career changers that need to take all or most of the pre-reqs for med school, I recommend applying to the Career Changer Track at the San Francisco State Pre-Health Post-Bacc program.
A very supportive program that produces a lot of strong MD and DO applicants.
For a Career Changer: No GPA cutoffs but 3.3 + will make you competitive. That paired with either strong grades in a couple intro science/math/etc. classes or a streak of recent A's will make you a strong candidate. If you can't do either of those, then you could take the GRE. While not as useful for MD applications, a good GRE score is a great way to demonstrate academic potential to post-bacc programs.
Edit: I just finished their Academic Enhancer Track program so my opinion is obviously in no way biased.
I actually live in Oakland, and am a married student (meaning moving would be a lot harder, but not impossible), so SFSU is my first choice for a variety of reasons.
Firstly, I really like how the program is structured, both in coursework and the cohort system. Plus, out of the three places I'll be applying - SFSU, Mills, and Scripps - it's also the lowest cost (this is a little debatable with Scripps because it's shorter but with higher tuition, but hey).
I'll post a very brief summation of my stats below if you have time to give me feedback on where I stand in the applicant pool, but definitely don't feel obligated to do so:
GPA: 3.73 (both in CC and UC Berkeley).
SAT Score: 1340 (old SAT)
GRE Score: About 1450, maybe higher. I took the new one so they only gave me estimated scores to hold me over until the new scoring scale is finished and I get my "real" scores in June.
Extracurriculars: Very involved in the psych community at Cal. Worked on the undergraduate research journal and the undergraduate psych conference. Also work as a research assistant in two cognitive science labs, and am completing an honors thesis.
Volunteer experience: None yet, but I just finished my second TB test today, so I should be starting that soon.
Other clinical experience: None yet, but I reduced my courseload for a variety of reasons (mostly financial) so that I have time to find a part-time job. Since I don't need one urgently, I'm going to wait until I (hopefully) get one medically related.
