    I'm starting to see what you are talking about. This was just the first error I found. I don't think I'm going to use this engine anymore, I'm afraid it's going to send me down the wrong path.

    Just use the book exam engine on the CD. The additional CD one was the most riddled, and it asked you ICND questions that you hadnt studied for yet.
