Why 70% People Fail in CISSP ?

Many People will say that you don't Practice Enough Question, or you don't have experience
further many would say that because you don't think like a Manager, you fail. but this is not 100% correct!
The simple answer is they don't read complete syllabus of CISSP.

I have never seen any course that teaches complete CISSP Syllabus on the Whole Internet!!!

and that's why I felt a need to make this course, which covers the whole outline in a very comprehensive way
