Passed my CISSP exam today, 1st attempt
Have been studying for the past one full year, postponed four times included two times right at the end as I felt I needed a few extra days.
1) Sybex, 8th edition, cover to cover including practice questions and online Bonus Exams (included free with your book purchase). Highly recommended.
2) BOSON ExSim practice exam. Good practice for exam but see my note below.
No Videos or Cram courses for me! But had to work my tail off on the book and practice questions. Prepared my own notes/flash-cards. Went back and forth to the book on material as needed for further studying.
About the exam:
Goes without saying it was really hard. As has been mentioned elsewhere it covers generalities not specifics so high-level view/understanding is a must. Actual exam different to questions encountered in the book/Boson. Took all of 175 minutes (with 5 min break) to answer all 150 questions. A printed note was handed at the end at reception with the congratulatory notice. I was surprised as I thought with CAT format, you are informed right on the computer on results, or maybe it took all of the last right answer to pass the test for me
Highly recommend taking a 5 minutes break at halfway point even though it counts as test time. In my case really had to go use the bathroom but even without its worth it, my thought process was much sharper after the break.
Best of luck!
