Honestly I know very, very little about them. "Rumor" has it that NC will adopt them, almost assured to do so for class of 2007 and supposedly a real possibility for our class (2006). I don't believe it until I see it.
What I do know about it: it's about twice the cost of our boards in place now. We would be able to do it during our senior year so we'd be able to graduate with degree AND license in hand. It seems too good to be true. There are a few in my class who post here that know more, maybe when school starts again next week they will reply.
