Is it ok to be a Finance major, 29 P MCAT

I vote for research coordinator---I would even look to see if you could get something that is more clinically applicable.

I have a friend who is applying and he's an accounting major. I believe he told me that it is okay to have a business like major, but you have to explain why you chose that major and why medicine. I haven't heard anything about certain majors being detrimental for applying.

For your last question, I think you should do the one you enjoy most. Both of your choices have positives about them.

Med schools don't care what your major is. They care that you have a high GPA and do especially well on the prerequisites. Your GPA is very good. Your MCAT is below the mean of accepted students (and you could consider retaking to improve your chances, considering you have some extra time to try to improve the score). The better option for a job after graduation is the one you feel the most passionate about, as you'll have sufficient research credentials already, when you apply.

I'd mostly agree that the "major doesn't matter" as my degrees are finance/economics too. A consideration is how you will position your degrees in light of where you want to go (med school); this is simpler if you've graduated many years earlier as you can explain how you came to change your mind about your career, but if you have recently studied studying CAPM, NPV, and international trade theory but want to be a doctor, I'd envision some med admissions folks would be a bit confused.

Suggestion to strengthen your app is to take a handful of add'l, advanced bio/med related courses, gain lots MORE clinical experience, and then explain what made you change your mind to pursue medicine. I feel that stressing business admin (managing a process, an office, etc) is more relevant than finance/econ.
