One thing that might be interesting, and I don't know if you have the technology to do this. You might. I don't know much about technology and how this would work. You show in the diagnostics what someone's doing really badly at and what they're doing well at and actual sub subjects within main subjects.

It would be interesting if you could somehow push a button and take questions in that sub subject because I did notice that there were some sub subjects that I did very poorly in in comparison with the other subjects in the main subject.
