Be careful with the post-bac route. I graduated with a 2.5 and did a post-bac education degree. I averaged 3.8 during this program. Then I became a teacher and worked in London's public schools as a class teacher for ten years. An amazing experience! I decided to follow in my father's footsteps and make a career change to medicine. I applied to schools in the state I originally earned my degree (and did the teaching program) and I was denied. I couldn't believe it because I had already been accepted and my grades were better than the last time I applied and was accepted. Their reason: I had little to no science experience and space was very limited for post-bacs. A lot of people assume that going back as a post-bac is easy, when in actuality it is easier to get into a grad program. (Only reason I got in the first time was it was a program, not just generic continuing my education without entering a program.)
I was told to take some science courses at a community college to bring my grades up and show commitment. Now I'm worried because I currently have a 2.77 after the teaching program and I'm in community college. I should be able to get up to 3.2 by the time I finish my ore-reqs, but I want those to come from a 4 year, not a cc. I feel like I'll never get into a post-bac program, much less medical school. Anyway, don't assume that you'll just automatically get into a post-bac program. Retake those courses now while you're actually in the system. Getting back in can be tougher than you might think.
On a side note, this is my first post and I am a bit confused. What is a DO?
