I think people use the percentage weight of each exam domain to determine how much time to spend studying for that domain. Based on my experience with CompTIA exams, the domain percentage is not an accurate indicator of necessary study time. Just learn it all, people!
I'd like to recommend the CBT Nuggets CISSP Training videos. They're very very good. I've studied the Sybex CISSP book extensively and the CBT Nuggets training videos are much more thorough. I've learned a lot of new material.
I'm also studying for the CISSP right now, and I should be taking it in 4 to 6 weeks.
Just got the results..
Thanks guys, I am SO happy with the results.. and a bit as well
