The optimist side of me would say to apply with a minimum 3.0 GPA. However, the realist in me says there are many other factors to consider (MCAT, EC's, LORs, and PS). If you have a very strong application (in all other factors listed above), apply with a 3.0 GPA. Rock the interview and you may have a chance at some medical school in the US 🙂
To answer your question, if the rest of my application was outstanding, I would apply with a minimum 3.0 GPA. But, I would probably do a postbac the fall semester after I initially applied (and retake the MCAT, if I needed to), so that I could increase my chances on the next application cycle.
