Tracks
Six tracks, from Yellow to Black Belt
Each track is a series of marked and explained questions, drawn from the same bank as the entry quizzes. You can start any of them now, with no account and no bank card.
The Yellow Belt level is fully open: the questions are renewed every session. The Green and Black tracks can be tried on fifteen questions, always the same — enough to judge the tone and the difficulty before deciding.
