Break down categories better on practice tests.

You have to go through manually to see what subjects you got wrong, like Solving systems of linear equations, scatterplots, etc. I feel like they should add this to the "show score breakdown", which now only says subjects like "heart of Algebra". I think it should tell you which sections appear and how many you got right out of how many questions for each specific skill it asked.

Also what would be nice, but also less important, would be to see how much certain questions are bringing down your score. For example, if you got question 17 right, how much better would you have done?
