improvement

I have a quick suggestion where I think improvements could be made. 

Whenever I complete a test on a certain topic then mark as studied it would be great to see the test score i got for that individual subject. And maybe some statistics on that.

For example i just completed the new lesson on labour unions and my score was 88%. This is not perfect but i dont want to go back to it right now and im quite comfortable with that grade. But in the future, if the sofware kept it registered that the grade was 88% I might want to go back and try to improve it.

A system like this would certainly add more motivation to polish things up.

Kind regards

James
