What can I do for clinical experience for medical school?

Medical schools love to see people who have qualified as an emergency medical technician. My daughter took the training in her senior year at university. It was 3 evenings a week for a semester at a nearby community college. Her school even paid for it as a transfer course and she got credit for it. When she was getting her doctorate she worked for the university's EMS department and she found her school offered the training as a 400 level course and all the other EMTs there were pre-med students.

Even the 200 hour internship as part of the training is more real medical experience than you can get anywhere else.

You dont need clinical experience but you do need things like shadowing, volunteer work, maybe some research work with profs etc. They could really care less that you were a phlebotomist, but going to central america to render aid, build clean water etc--that is important.

One thing a lot of my friends in college did is take an EMS course and exam. Aside from that you can ask to shadow a primary care physician or somehow get some shadowing hours in a hospital, if possible.

You need zero clinical experience to apply to med school.
