I know of plenty of medical students who don't have stellar GPAs; those who don't, however, have other things to convince the medical school that they are ready and able to handle school. Many go to grad school... Normal MS or PhD programs; that way, you have other opportunities in case med school doesn't pan out. And it will strengthen your application with good (hopefully!@) grades in grad-level courses, as well as research and teaching experience.
My advice to all pre-meds out there: don't let ANYONE tell you you can't get into medical school. *ONLY* medical schools can tell you that, and even so, that's only for one particular application (you may improve it and reapply and gain admission!) Follow your dreams, and only accept defeat if you try and fail, not because others tell you you'll fail.
