Think about a book you read last year. How much of it do you remember? Could you list ten things you learned from it? Can you even remember what books you read last year? Back in school, you actually had to remember what you’d read. Tests, term papers, and book reports were all just ways to help you retain that information. So engineer Robert Heaton invented a three-step system for reading a book like a student. (And if you are a student, it might be better than your current habits.)
