If they were overseen by another doctor with more experience it might be OK.

Besides I'd assume with this setup the future doctor wouldn't start with brain surgery. Maybe stitch up cuts and set broken bones, working up into more complicated scenarios.

I mean, I've always done my own minor doctoring anyway. And people did for a long time, it's only recently a long stint in college was required.

Granted this approach had variable levels of success, but the idea you have to have formal schooling to fix up any health problems I'm not sure I buy.

What was the infection rate in this “pre-schooling” period? We used to use leeches, blood-letting and cocaine medicinally, that doesn’t make them good ideas for today’s society.

We still use amphetamine to treat ADHD and leeches to help heal skin grafts. I believe that even cocaine is used in medicine today, but I'm not quite sure.
