Are internships a place to learn or a place to apply knowledge?
When applying for internships as a high school student how much prior knowledge should I have? For example if I were to apply for a medical research internship, would taking Biology and Anatomy be a sufficient enough or should I be doing more research beforehand? If so what are some good and reliable resources to do so?
So internships are hands on work (not theoretical). As for prior knowledge look to see if the internship requires knowledge in a field or if you learn on the job so to speak.
Likely for a medical internship biology or anatomy would be sufficient. But it depends on type of medical internship as chemistry might also work if it is lab based.
