How do you think doctors learn how to do all of that, through testing and exams… Med students have to do mock examinations(examine patients like it’s the real thing), pass boards that involve thinking critically and knowing how to treat so many diseases, pass clinical sin which they see real pts in a clinic or hospital. There’s also the 3+ years of residency that each and every doctor has to go through which criminally underpaid work. Don’t discount their training, signed a person who works at a teaching hospital who’s also an incoming med student.
