Does it look better to do a double major or minors?
Professional schools do not give greater weight to double majors, dual degrees, or minors. If you have a specific interest in another area outside of your major then they may make sense, but there is just as much worth to taking courses from multiple departments as your electives. Ask yourself what you want to learn about and how those classes are preparing you for a career in medicine, or how they are supporting your personal interests.
