The mastery model has landed!

The new progression and mastery system is now live. You can read more about it in How mastery works.

Your historical exam-mode attempts are automatically used to estimate your current mastery score in the new dashboard. The model draws on the same family of Rasch methods used by UAT-UK to score and standardise the TMUA.

I hope you find it useful—I spent far longer building it than I had originally planned... :)
