I'm wondering about this for next year (2013), and specifically am wondering whether there is some kind of demo lecture online to see whether it would hold DD's attention. I think she might enjoy it, but it can be hard to predict sometimes how she will react to things (especially an entire day of math, for two weeks) and it would be nice to see whether she was interested in a snippet. I'm going to also email the Epsilon person at the email above, but wondered if anyone here knew--or knew of anything similar. If that's not available, is it like EPGY, or Khan academy, or anything else I might be able to show her?
