Thanks, that's really helpful.
So, I'm going to be straight with you - as it stands right now, things are not looking good for you.
I'm not saying it's hopeless, but you need to right this ship immediately or else you're going to permanently ruin your chances for medical school. As a post bac pre-med, I think you're expected to have learned how to play the academic game by this point and to earn stellar grades in all post baccalaureate work. This is ESPECIALLY important if you're trying to prove you can handle the rigors of medical school after a subpar undergraduate performance.
A C grade in Gen Chem as a freshman? OK, sure - not great, but that can be explained as an initial difficulty adapting to college level coursework. As post bacs, however, there's an expectation that we'll have already mastered good study skills; the bar is set higher for us. Those Cs are not going to be regarded very kindly, I'm afraid. You need to ACE every course - I mean, 4.0, no exceptions - from here on out. You will also need to score as high as possible on the MCAT, but you can worry about that later on.
Reading your academic history, I'm concerned you have some deficiencies in your study skills. Do you know why you're not getting all As at this point? I think you should, at a minimum, visit your university's study skills/tutoring center right away to figure out what's going on. You may choose to visit your university's counseling center if you're having attention/emotional difficulties. Do you have any other ideas about what might be contributing to these challenges?
I believe that you can get back on track, but you've got to get a handle on your academics immediately. Let me know how I can help, or if I can answer any other questions. This is going to be tough, but I don't think it's insurmountable yet. Good luck!
