Hello, I just passed the CISSP exam today. It took me around 3 hours with out any breaks. I found the CASP exam more difficult than this one. Don't get me wrong, the CISSP exam was not easy by any means...I wasn't 100 percent sure I passed. I achieved the CASP Cert about a year ago and I found a lot of the information from this CASP book: CASP-002 Cert Guide, by Robin Abernathy was helpful in passing CISSP.
I have read the majority of the CISSP books and watched the majority of videos, the easiest book for reading is the Sybex 7th edition Official Guide. This book is a great introduction and the practice questions are good as well, however there is gaps and it will be difficult to pass the exam just reading that book. The CBK 4th Edition basically answers the majority of the questions on the exam however it is a monster size book and a dull read. I read it twice

Best videos is the Cybrary by Kelly, and the Sari Greene series. She has a 24 hour series that was an excellent resource, these videos really filled in the gaps. I have a Safari books online account and her video can be found there, she also has a 6 hour exam prep that was beneficial as well.
Best practice questions is the Sybex Practice tests that is about a year old, these are about as close you going to get to the exam as you can get. I was getting around 78% for each domain, some domains I was getting lower so I went back to the CBK and re-read those domains that I was weak at which was a huge help.
I have 12 years of system admin work, and 6 years as an Information Assurance Security Officer. Some questions I was able to answer by experience.
