In preparation for the A+ exam I had already purchased the Exam Prep and Exam Cram books and CD package. To give myself an extra "edge" I also bought this disk. It came with no instructins or documentation of any kind. The biggest disappointment was the questions. There was not ONE QUESTION that I didn't already have on the disk that came with the first package I had alreay been using. I can't believe that the people who offer these series had the nerve to market this disk separately.
