Although medical schools say clinical experience is not a strict requirement, it might as well be a prerequisite. An applicant with no clinical experience will be doing him or herself a huge disfavor. Medical schools are extremely hesitant to accept applicants who have little to no experience in a clinical health setting. In fact, if you have no clinical experience, your chances are almost zero that you will be accepted into medical school. Medical schools need to know that you are serious about medicine before they let you into their schools. If you have never worked inside a hospital, health clinic, or something of the like, they will write you off as an uninterested applicant.
Make sure you research all the positions available at your college. Freshmen year is not too early to explore extracurricular activities. Medical school is competitive and you must do everything you can to stand out from the crowd.
