I converted Shon Harris videos into MP3s and I spent something like 3 months listening to them while commuting to work. Everytime there was a red light or something, I would put a key word on a piece of paper about a particular topic I found I shoud read more about.
Then, I registered for the exam: 17 days left!
After this, I started reading Shon Harris book, but only for spots I took notes about while listening to the MP3s. At this point, I started taking test exams like crazy. I answered 1800 questions from 4 different sources before taking the actual exam.
3 days before the exam, I bought a second CISSP book from Stewart, Tittel and Chapple. Very, very good book. It is a nice complement to Shon Harris' book. I was amazed at the amount of stuff that wasn't in Shon's book.
So for the 17 days that I really study, I had no life. Waking up at 4:00am and working/studying until 11:30pm every single day.
The exam was hell (I am a French Canadian and I only learn English at 18 years old) but I ended up passing on my first attempt.
Very different then OSCP. It's like drinking beer then milk right after. It taste funny and you can't wait to go back drinking beer...
