Hi all,
Backround: I am a network and systems engineer with 10+ years of experience, and I moved to the InfoSec field about 3 years ago starting as a pen tester (Total of 13 years in IT with one gap year since 2001). I decided that having the CISSP is worth trying and would give me a much needed career boost. After certain age, one should move up and forward or become unemployable.
I started my study with AIO 6th, but got bored after the first couple of chapters. Then I discovered Conrad, read it cover to cover once. After getting fair results from Conrad and AIO post-chapter self-tests, I did the comprehensive 100+ part at the end of AIO and got a result of 75%. Took another small (50 questions) test from the ones that come with the CD and the result confirmed my level of preparedness as I got 77%. I analyzed the results, identified what I need to concentrate on and read the respective AIO chapters. Today I sat for another 2 sets of practice questions from AIO CD and got two extremely different results. I was shocked to receive 37% (!!!) on the first one, and an actual "pass" with 83% on the second one. Has anyone experienced similar day and night differences when doing comparable practice test? Honestly, after the utter failure on the first one, I was convinced that I have reached my own level of incompetence, and it is time to give up IT, get some land and go farming. The excellent result on the second one left me in a very strange state of mind, so I would really appreciate your thoughts and comments on similar experiences.
I know that reading Conrad once and going through half of AIO is absolutely not enough for the exam, I don't consider myself even close to be ready for the exam. Unfortunately it took me about 2 months to do even this as I have to do it while working full-time and being a full-time husband and dad. I am doing my best. I am just puzzled by the huge discrepancy in the practice exam results that I got. My mind is screaming "drop it, it's not for you", and the next second I am like "lots of people are doing it, you have no excuses". A monster that exam is
