Query: Needs organization

I picked up this book, and I am very dissappointed. It doesn't have much organization nor aim for what level it wants to teach. Some of the stuff is very easy; other parts are difficult. But it's not presented in any kind of order, so first-timers will get very intimidated, while experienced players will get next to nothing, provided they have the patience to mine for the information. A detailed table of contents and subject breaks would have helped tremendously.
