It is great to see that you have a career in mind. To answer your question, you can really major in anything when you are in college. However, I would research various medical school programs to see what the requirements are, so that you can complete those requirements during your undergrad program. It might be beneficial to major in something like biology, so you can be prepared for the rigor of medical school, and are well versed in its terminology.
Also, each undergrad program has various majors, which will consist of many different requirements. Research your majors of interest and see what classes you would enjoy. In terms of minors, you can also minor in anything. Your minor does not have to be related to your major at all! This is where you can fulfill you desires for art.
Amit recommends the following next steps:
- Research college majors, whether is it the school or your attending, or planning to attend.
- Research medical programs for requirements in addition to the MCAT, this may help you figure out courses/majors to target when you are in undergrad.
- Research minors at your undergrad program for areas you wish to learn more about.
