Query: Disappointing Study Resource

I did not find this study guide helpful at all. It merely presented terms to be familiar with for each knowledge area (without definitions or explanations as to why they're important) and sample exams. I grew increasingly frustrated with the exams because I was scoring significantly lower (10-20 points) that I was experiencing with all the other sample exams I was taking (e.g., Mulcahy and PMP Tools). The cute scenarios didn't bug me as much as the lack of valuable insight into how to improve my score on the exam. After a couple of chapters, I simply stopped using it. Having now taken and passed the exam with 30 points to spare, I can confidently say this book was a waste of money.
