This is such a progressive step. I love to see this sort of initiative. It makes it very viable for any young students looking to try and get a step ahead. I'm actually going to send the algebra course to my younger brother now.

The speed at which changes are occurring in the U.S. higher education system is amazing. Colleges and universities that don't adapt -- and adapt quickly -- will go down the same path as buggy whip makers and dead-tree publishers.
Bravo. I'm interested in using this for my kids to avoid some bad teachers in high school. The fact that the classes would be accepted at many colleges will help them to be accepted in high school as well.
