content: I found this review to be clear, concise, and have lots of great information particularly useful on the exam. I wouldn't go so far as to say this should be your only resource, but as I was taking the Network+ I found myself remembering a lot of answers because I had read them, heard them, and spoken them. This audio review is very well produced, and the speaking parts are done very well. Also, this is a study resource that can be used while you are doing other things such as exercising, driving, or even sleeping at low volume. Credit to Coriolis for another fine product.
