I don't know much about either of them. There are so many of these things now. It seems like every few days I hear about another one I hadn't heard of. And I don't really know what goes on inside of any of them. Except Imagine K-12, which was started by friends of mine with my encouragement, and one of whose founders, Geoff Ralston, is also a partner at YC. IK12 is definitely good, and we recommend education startups apply to them.
