Is your practice paying off? Your readiness page now shows the trend

Readiness shows where you stand today in each exam domain. It now also shows whether your practice is improving.

Accuracy over time. Below the domain bars, a new panel shows your percent correct on your practice answers, with the number of answers behind it, and a bar for each of the last 12 weeks. It's practice accuracy, not an exam score or a pass prediction.

Cards you miss most. A short list of the questions and cards you get wrong most often, each with how many times you missed it.

Drill the weak spots. A "Drill N from " button for each lesson starts a session of just those cards. On a deck's own page the button reads "Drill these".

Until there's enough history you'll see "Not enough answers yet to show a trend". Answers count from late October 2026, when we started keeping them.
