This course is excellent, Mr. Browning really takes you through the course and focuses on what's important. I am able to listen to the audio book on the train as I commute every day and it is downloadable so you don't need a data/wi-fi connection to listen. His approach to subnetting is second to none and totally disarms the intimidation of the matter. His book is fun and easy to understand and most importantly it reads like a book, not like an instruction manual written by a cyborg.
