Due to the fact that you may be highly likely to need loans and that you want to pursue graduate school, I would definitely focus on opportunities to get costs as low as possible. You can go to med school from anywhere. Med schools care about your GPA, MCAT score, and that you’ve taken the required prereqs. It’s often easier to get a high GPA and be at the top of your class when you’re not at the most prestigious school…which then helps you get into med school. The less prestigious schools are also often the likeliest to give the most generous merit aid.
