When you're doing poorly in school, the standard advice is to
Work Harder
. That will help a little, and there is no escaping the fact that hard work is necessary. BUT! More effort usually means doing more of the same ineffective type of work you already did in the past. It wasn't very successful then, and just doing more of it isn't going to help you much. You'll still be wasting a lot of your study time working in an inadequate way and not learning well.
What you need is to
Work Smarter
-to use study methods that will increase what you get out of each hour of study and help you produce good learning. This short book explains how to do that. It does so by describing four steps that are both easy to understand and to remember. Yes, you'll get plenty of useful advice along the way, but you don't have to memorize a long, boring list of study tips. Just by following the four steps in an effective way, you'll be carrying out the book's advice, and soon you'll be on your way to becoming a successful student!
