Though the study guide appeared to be very comprehensive about the exam, but there were many topics on the exam not covered in the study guide. Moreso, many of the topics on the study guide (it felt like at least half) never appeared on the exam. The study did help with quite a few questions, but certainly needed paired with multiple other sources for review, which is not how the guide was advertised. I am thankful to have had it, and it did help to an extent, but it was misleading.
