I would recommend moving your post to the postbacc or pre-med forum where there's much higher traffic and where more people might have better input for you. Have you taken all the science pre-reqs typically required for med schools? Usually the SMPs have similar requirements to med schools. If you haven't that could be why you didn't get in the SMP's. I'm not sure why you would do postbacc if you have otherwise taken all those basic science classes. You don't want to waste money by taking random continuing undergrad classes. I would sit down with a pre-med advisor at your local college and develop a plan. Maybe your best course of action at this point is to pursue a master's in any one of the biomedical science field where you can improve your credentials for medical school. without knowing more about your circumstances it's hard for us to provide useful advice. Again, you should repost your question in the pre-med or post-bacc forum.
