The book is concise enough to not need to take notes imo and I have no background in psychology or sociology. I memorized the whole thing and went through it 2 more times over the course of the few months leading to my mcat and these stuff gets into your head pretty easily after the first review. The problem is how they apply so you have to do passages to see what you're getting wrong/missing. I ended up knowing ~95% of the terms I saw on the PS section on the real mcat.
