You can take my word for it, that for Linux training, it is the best thing I found. As a total newbie I started learning with this set less than two months ago. Two weeks ago I passed last exam, and today I received in mail large envelop with four pretty certificates with my name on them. The training is organized around video lessons. First you watch the lesson, then you repeat all the steps on Linux computer (Fedora is included in the set), read manual pages etc. The videos are simple but very effective (may be they are effective because of its simplicity). The set comes with everything you need to learn Linux. The course produced with very clear understanding of educational needs of beginners. The exams aren't that simple, not to me at least. I used all three attempts to pass for all of them.
After my second failed attempt on first exam, DVDxDVD UNIX Academy called me to explain why I'm making repeated mistakes on certain questions!!! At this point I was almost speechless. For the price paid, you get knowledgeable instructor who knows what he talks (I think he is Russian), complete training and certification set, certification exams, printed certificates (after you pass the exams), library of PDF books and personal, over phone training session!
I can't ask for more. For a price of a thick Linux book, I received complete solution from an introduction to certification.
