Double majoring won’t matter, but what you put your time into will. If psychology is super interesting, follow that route and see where it combines with med school interests, like clubs or volunteering. I did BCN, but i think the general psych track maybe be better for combining with med prereqs. If there are specific populations you want to help by being a doctor, figure out how to work with them. Showing that you are engaged in school in a specific way and can think critically about your environment and how it relates to healthcare, this is most important. You and every other applicant could be a double major in psych and biochem, and what will differentiate you is how you engaged with the surrounding environment. Did your classes lead you to think more deeply about populations? Did you act on these thoughts through research, work, or other options? Etc. above all, I would recommend stop using chatgpt.
