The thing I would counter is that "people studying medicine in medical school" is a bit of a bubble. This is particularly because the step of creating notes isn't necessary. There are many, many pre-built notes and study guides to select among. It's more about finding one that works for you and adapting it to the specific coursework.

The point being that if you are studying medicine the notes for review already exist and you just touch them up. You spend very little (if any) time actually creating them. I would certainly agree it's a waste of time to create your own notes in medicine.
