To me, traffic school is a neccesary evil that must be endured every few years. AZ Crash Course fulfills the requirement, but that doesn't make it any fun. The material is dry and boring and it makes for an extremely long day. If you are lucky enough to get in a class with an interesting instructor it probably helps, but unfortunately that was not my experience.
I did learn a few things from the experience, but there is nothing at AZ Crash Course that makes it different or better than any of the other schools around, and it was by far the most boring traffic school I've ever attended.
