There is always a limitation on reusability for tutorials. Once the material is learned, one rarely returns to brush up. However, the info presented in Complete Training is so expansive, chances are you will return to it at one point or another. Class On Demand makes their product easy to reuse by including detailed information organized by chapter and project. It is easy to skip ahead and find the information you are looking for if needed. With that being said, Complete Training is not a DVD you'd want to toss away once you complete the training. Rather, it's a bit like a training guide which you will want to keep on the edit suite bookshelf for future reference. In addition, it is worth mentioning that accessibility is becoming another strong-point of the Class On Demand series, as they have just released all of their tutorials in online, streaming format.
