I have several children who are homeschooling and we've found Khan Academy to be quite adequate at supplementing what we are already doing. The kids have been on Khan for several months but, I felt I wanted to play a more active role in monitoring what they're doing. Hence, I opened up a classroom where I can assess what they;re doing and where their weaknesses are, assign lessons to strengthen where they're weak, and monitor their progress more closely.

The problem is that I don't to overlap what they've already done. Is there any way to import what they've previously done on Khan Academy into the new classroom that I opened for them?
