Each dot is a question. Red ones need the most work; as you get them right over time, they move towards green.

Each question climbs a short ladder: not tried → learning → getting there → mastered. A correct answer moves it up a rung, a missed one sends it back to the bottom, and it takes three correct answers, spread out over days rather than minutes, to reach mastered. Mastery in the table above is how far up that ladder a subtopic's questions have climbed on average.
