I've seen the materials and read up on it quite a bit. It's a TOUGH curriculaum, and very harsh judgement from the Kuberts. But it's just as good as going to the school, minus the 12+ hours a day of drawing boot camp.
It's a bit expensive, but I know if I had the extra money I'd get back into my penciling and get some submissions sent in. God, I'm so out of practice.
To be honest, the best experience I've had is doing your stuff in your own style and taking it to shows to have the artists critisize them right there.
Saurus if youare an artist I wouldn't mind seeing your stuff. Maybe I could offer a few pointers or technique ideas.
