What actually happened
Every number below comes from a recorded lesson attempt. Here they belong to an example learner, until your own child finishes a lesson. A lesson marked complete is not a lesson mastered, and this page keeps the two apart.
Example learner. This is what it looks like after a few months of practice. Finish one lesson and your own record replaces it.

Your path today
Lumi keeps every slip you have ever made on this device, even from months ago, and brings those skills back until they stick. Saying why it was wrong is where you slip most, so Lumi will point it out when it comes up.

“Proved on a later day” means the learner caught every step unaided, then came back to the same skill on another day and did it again. It is the strongest claim this page makes, and it is still not the same as mastery.
