Forums IMPORTANT: PLEASE READ PhotoReading, Memory Optimizer An Excellent Tool For Photoreaders

Do you use headphones to listen to the discs?
There are three disc, isn't it confusing to determine which disc to use between building knowledge in any subject (disc 1) which I think is studying, and (disc 2) which volition says to use for memory intensive studying? I have the disc, but can't choose between 1 & 2. I'm studying for the CCNA certification which is building knowledge but, on the same token, I'm studying and need to remember the theory and concept. What do you think? Thanks.
