I agree with a lot of the people here that said this or that source was of no help, except to give you the basic information and set the foundation from which to draw your 'best answer' based on ALL of the materials. There were very few questions that resembled any of the questions in the prep exams unless "hell if I know" was the right answer to most of them (it wasn't). Having said that, Kelly Handerhan's voice, quips, mnemonics, illustrations, etc. helped probably as much or more than anything, for me, but there again, as a single source, there is no single source and I wouldn't even consider depending on one. What seriously irritated

me is when they disagreed (i.e. the Official Guide didn't even list Strong Star), which in those cases, I went back to the original CBK to get the source of truth (or so I hoped). This is not to discourage anyone of you out there in taking the test or scare you any worse than I am sure you already are, I am saying all of this to let you know that everything you review, study and read, and all of the prep tests you can get your hands on and can afford (DO NOT PAY MORE THAN $100 for anything - it is a waste of money), and getting all of the points of view, perspectives, etc. was my greatest help......that and a "what the hell" attitude, knowing I could take it more than once. I sat for 4.5 hours without moving. Took a break, then went back and reviewed the first 100 again. I had a couple of "what was I thinking"

moments and changed a few, but for the most part, I went with what I had answered originally. At 5 hours and 15 minutes, I hit the exit exam and submit...... I think all of the prep tests, reviews, reading and Kelly's videos were the biggest contribution to my passing the CISSP on my first try. I am not a network person (at all) and I come from healthcare insurance / IT PM and federal contractor experience with web, database, analytics and software development with some cyber security auditing in my many contracting and job backgrounds.

For managers, it is very technical, for technical people, it is very manager-ery - that's because it is a true mix with lots of judgment calls in many scenarios - again Kelly's little quips helped me there too.
