My recall of things I got wrong on the tests is almost visceral, like it was traumatic that I was wrong. I figured this out pretty young and my studying habit was very similar to the methods employed for learning foreign language vocabulary or typing; progressively focus on the things the person still gets wrong.

So I'd read my notes and highlight or copy out only the facts that I found myself being surprised or flummoxed by. I'd go over those a few times, do one more scan of my entire notes, and sit before the test just going over the hard ones again until the instructor started handing out the test.
