Stanford "Class2Go"

Another online education system from Stanford...

Stanford Class2Go - Coming Soon:

Formative and summative exercises built on the Khan Academy's exercise framework provide new formats for taking your learning to the next level.

That is, not by default. With my own "Explorer" for it has it :)


Browse an image index to find specific topics and quizzes within videos
