Keeping all user data would be too overwhelming. What is needed is something which can measure progress.
On a broad chapter topic, like say fractions, students should be able to get an idea of what they have achieved at different levels. These can be worked out from ratings. Levels can be measured as 0-9 for ratings less than 1000. And then A B C for those above.
In a particular level, a colour coded bar based on correct/attempts. Those numbers can be displayed within the bar. So only two numbers are needed for each chapter in each level. If there is data for more than 3 levels, then only the top three levels are shown. (The level needs to be present as part of the bar).
This lets students know which topics need most work to level up. If they are aiming for a grade 4, the advice could be to level up topics to include those with a rating of 400+, rather than to keep pushing topics to higher levels.
