content: This book is 50% old exams (old, and current exams are available for free on the USPTO website) and 50% snippets from the MPEP (also available for free on the USPTO). The snippets are have plenty of errors (both typos and in content), its outdated, and provides almost no useful information.It provides only the highest level of overview that doesn't come close to anything that will help you pass the patent bar. If you don't want to spring for the expensive study aids and think this is a cheap way to get some help, you're going to be very disappointed. You're much better off slugging your way through the old exams and MPEP on your own. If you write down the first sentence in every major section of the MPEP, you've just about wrote this book.
