This was probably the toughest exam that I've ever sat!  It was 6 hours long and had some of the toughest questions I've seen.  Some questions were also annoyingly vague!  The exam is paper based with a procter.  I had to travel 100+ miles to undergo this bizarre form of torture.  Upon leaving, I was completly convinced that I'd failed.  Luckily I was wrong!  ISC2 don't provide your passing grade, but I'm sure mine wasn't great!  Being British a lot of the US legal aspects  and items on HMO's seemed unfair / irrelevant - replacing these with UK equivalents would seem better, especially international standards such as ISO27001.

I used the CISSP All-in-One Exam Guide by Shon Harris.  This is pretty much the defacto text for the qualification.

The website cccure.org have some great free resources, including test questions.

Good luck if you decide to go for this exam - it's not easy!
