So I took the CCSP today and failed it. I already have the CISSP, though I took it back when it was a 6hr test and the whole 'non-adaptive' type.
Difference from what I can tell, the information that was in the books for the CISSP (ISC2 CBK, Shon Harris, Eric Conrad and the bootcamp) were on the test.
The 'Official Study Guide', the 'Official CBK' and the 'Official Practice Tests'... I'd be very save to say that there was maybe 20-30% of the material in all of those books combined in the test. I took a bootcamp, paid for by work, and also read the CSAv4 materials as well.
So after failing, I'm looking around and apparently ISC2 changed the test content in August of this year. Then I look for the books. ISC2 points you to Amazon which states the "Official ISC2 Study Guide" isn't going to be available until November 2019, the "Official CBK" won't be available until April 2020.
So I don't think there is a little changed but there has got to be a fairly decent amount changed to be that long for the guides to come out.
But in all honesty, I don't know how you put a test out or change a test to incorporate the new data/topics/whatever if you don't even have the materials available to study.
Whatever... Rant over... Not taking it again unless work wants to pay again.
Just my 2cents
