Best advice in the thread so far. There is no magic involved in getting into med school. Take the dozen or so required lower-division courses (which any college in the country offers) and do well in them, get to know some profs for personal recs, take part in medical ECs, prep for the MCAT. Do this at a college that’s a fit for you. If you’re the kind of student that can get acceptance letters to Harvard or Haverford undergrad then you’ve already shown the academic ability and ECs that puts you at the top of the country’s undergrads; it’s no surprise these kids can end up in the 50% of med school applicants that are admitted.
Not addressed yet is why med school is right for you. Many HS kids think they need to pick something as they enter college and since they aren’t aware of more than a handful of career fields medicine is attractive. And even within medicine many can only name a few occupations such as doctor or nurse but these are far from the only in the health field that help people. Physical therapists, radiology techs, speech pathologists, physician assistants, nurse practitioners, to name but just a few as shown on http://explorehealthcareers.org Careers that take less than 11+ years of education and training and the immense debt that comes with a M.D. If you don’t have exposure to exposure to medicine such as thru volunteering then I suggest thinking of yourself as wanting to explore medicine, not someone who’s made a decision.
