This serves as a general guide but some of the information in this book is already out of date. For example, when cleared to taxi to a runway but to do so, you must cross another runway. Are you cleared to cross the non-active runway? The book's answer is yes, but actually that rule has changed. Now you must have separate clearances to cross other runways. Not only could this fail your checkride, but this is even more potentially dangerous later on as you fly as a private pilot.
This is the 9th edition, and as of the date of this review, it's the latest edition. They should either publish a new edition real soon, or put pocket inserts in the current editions to reflect the latest rule changes.
IMO you should rely on your CFI and latest FAR/AIM for all the rules, and only use this guide informally to get a taste of what kind of questions to expect on your checkride.
