I have a BS in Biology with a 2.9 GPA. I have now realized I want to go to medical school. I obviously need to take a lot of courses to bring this GPA up. One thing I have developed a strong passion for in the past few years is geology, and if I never got into medical school I think I would be happy in that field of science as well. If I were to complete a geology degree (about 45 more credits) along with retaking a few med school prereqs for a better grade, how would that look to med schools? In other words, would it matter that I look a bunch of upper level geology courses instead of more biology courses? I am passionate about geology and think I would do well in the courses. Thanks in advance.
