This book would be useful for people who have never been exposed to methods which help make them more productive. It mostly contains methods and ways you can become more productive by using certain methods that can be quite well known. So if you are looking for something revolutionary, this book is not the one for you. This book suggests quite a few methods that may not be scientifically proven to make one more effective. These are methods which do not aim to solve the problem/issue at the root cause of it. This is most prominent in the methods suggested to deal with exam anxiety. Also, there is quite a lot of repetition in this book and a good amount of useless information and examples. People who are already fairly productive and good at studying, this book can help you, but not by leaps and bounds. People who are not productive/ good at studying at all, this is the book for you.
