Learn

Work through each topic's numbered subtopics in order — every subtopic is a sequence of learnpanels interleaved with one-question quizzes, capped by a final mastery check. A clean run with every quiz right on the first try locks in 100%. Score drops 0.5%/hour while you don't drill it — keep revisiting to keep it pinned.
