I keep reading about how people come very close, and needing recommended guidance etc. A lot of the threads here seem to give the same common advice, same books to use etc, and study methodologies.
one common item I see left out, that really helped me was the Aide Memoire(SP?) by Eric Allaire:
Site Internet de - Accueilhttp://home.cogeco.ca/~ericallaire/Document/CISSP_aide_memoire_e_%20v52.pdf
I used the Shon Harris AIO, (ISC)^2 official cissp CBK, this forum, a different forum which I won't name, and freepracticetests.org questions(paid account). I chained many quizzes in a row consisting of 20, 30, 40, 50, sometimes 100 questions. Quizzes for 2-3 months straight.
Overtime, everything gel'd together.
I have 7 years of IT Experience, bachelors in Management Information Systems. If you are "aware" of technology, with some decent work experience, and you study hard, the test you will most likely pass.
Also, approach the majority of the questions, with the perspective of "how would a manager solve the problem"? A lot of times people want to select the answer that the "sys admin/technical implementer" would like to chose, but always remember, what is in the best interest of the company, cost effective. Not what the "know it all system administrator" would want... I can't stress that enough, think like a manager, and what would the manager select, and not what the system administrator would chose.
Studied for about 4 months.
The PDF is great to review over the course of your studies. I also read it non stop for the last two days.
