I took Driver's Education in high school, but that was just a class to learn the rules of the road and such, there was no driving involved. It helped me pass the written test, but was generally a waste. I can't really say much about the actual driving instruction, although since you said you have already been driving for 6 months (!) I would say that you probably don't need it. Couldn't hurt, though. Maybe you'll have fun and learn a thing or two.
