Passed CISSP today!
Passed today at 100 questions!
Thanks to everyone who offered suggestions and advice, either directly or by posting your own experiences.
I used Cybrary.IT video series, Sybex 8th Ed. and included practice questions, 11th Hour, and Boson practice tests. Supplemented with Quizlet, Wikipedia, and the Memory Palace PDF.
Like everyone has said, it is all about understanding the concepts. The questions were worded in such a way that if you don't understand the underlying concepts, you won't know what they are referring to.
