content: A good program. Four disks -- great value for the money. Do give yourself time to learn the lessons, though. If you're an "auditory" learner, this is a great program, but if you need to read AND hear, it's obviously not as effective. The company does provide a modest-sized text, but it's pretty limited in its scope; but then again, it does have to fit into a DC case. Again, this is a great value for the money. Definitely worth a try.
