Well, it's quite technical, but not too technical. Understand each concept to eliminate the wrong answers.
Don't be discouraged by what people say here about failures, the most important thing is to prepare and believe in yourself.
Thank God for success.
Congrats
Congratulations. It is not an easy exam. I and another CISSP signed up when ISC2 asked for volunteers. We both agreed that it was not easy but appropriate for the level targeted. We did pass it during the pilot stage of the exam. I read the self-study materials that they had at the time; he did not. I later bought the eTextbook after it came out but don't think that it added anything. I wanted be able to speak about it intelligently as helping people improve themselves is important to me to give back to the profession.
Congratulation!
