Whether it is a good school is really up to the person themself. But read through The Aviary to get the perspectives of about a dozen or so students there now or recently graduated. Some of us even put up weekly descriptions of classes and such. You should get some answers there.
Otherwise ask some distinct questions so we can answer them for you.
As for my opinion, it was an excellent schooling. Expensive, but paying it back is easy enough. You probably won't be able to find a more safety oriented training anywhere.
