4 stars (Very useful + PMBOK must - Passed exam) - Yes this book is good. But ONLY in conjunction with PMBOK guide. The Inputs/Tools/Outputs are not that intuitive in Rita's book. I had several questions that I could answer only with PMBOK's knowledge. 5 stars (Easy to Understand) - Good study guide that is easy to read. Nice sample questions at the end that can help prepare one for the exam. 4 stars (Found it very useful for PMP Prep) - Initially I did not buy this book when I was starting PMP preparation. When I heard about the Book and CD in many forums, I was curious to try it out. The book and CD together turned out to be very useful, even through I wouldn't say those were essential for my prep work. The CD comes with 1300 questions, which gave a whole lot confidence after trying out. The prices are bit high though. I also used Andy Crowe book and lots of reference on PMI web site. I passed PMP with an overall score of 82%. ...
