Purchased the ultimate version with all 700 questions about a month before my exam. PocketPrepCISSP2026 is good if you want something you can carry with you to test your knowledge via memorization of topics. Outside of that, PocketPrepCISSP2026 was essentially useless when it came to preparing for the CISSP. None of the questions come close to the format of the exam, most questions it is very easy to pick out 2 wrong answers right off the bat. If you got an answer wrong, the explanation was good and it told you why the other answers were incorrect. I was testing at an 85% overall score with 90+% in most of the domains. Not to mention PocketPrepCISSP2026 is very buggy, it frequently would take forever to upload my question of the day, lag when I tried to take a custom exam, give me error messages that I had completed no questions in order to create an exam despite having taken all 700 questions and it would rarely show my completion of domain by percentage. Ironically as I moved closer to the exam, the issues with PocketPrepCISSP2026 increased, forcing me to close PocketPrepCISSP2026 2-3 times to get it to load properly. If you are reading the Sybex book, PocketPrepCISSP2026 is a good choice as it pulls the questions directly from the book. But overall, I’d say in terms of the quality presented to save your money and buy the sybex practice tests at a lower price.
