Is anyone using this fairly new Mission feature on KhanAcademy.com? I have assigned my daughter iGeometry and Chemistry, and it looks to be a complete curriculum. They also have the Crash Courses on Khan for Chemistry for support. They have some cool partnerships for classes my daughter likes such as Biodiversity fromCalifornia Science Academy, but that isn't part of the Missions that can be assigned, it's kind of like an "elective science."

I like Khan's approach to teaching and I believe the videos paired with the knowledge map and practices and tests ought to do the trick, but I'd like feedback from anyone who has used it as their curriculum, as opposed to just for support. Thanks
