<p>At your age, it is highly likely that you will change your mind often as events like courses and activities affect the way you perceive the slate of academia you need to take for various disciplines. Nothing wrong with keeping the medical field open as an option. To become a doctor does not mean having to be a science major. Out of all of the courses you take in college, I believe the only ones required for med school in the sciences are Chem, O-Chem, Physics, Bio with labs. Considering you will be taking 4-5 courses each term, that is hardly daunting, especially when will likely need a couple of science courses to graduate anyways.</p>
