Duolingo Learning Flow
About this model
The core learning flow of Duolingo: each step is one lesson, picked at random between Simple, Story, Radio and Unit review lessons, with harder types more likely in later units. Units 1 to 3 need 4 lessons, units 4 to 6 need 8 and units 7 and 8 need 9. Difficulty grows with every unit, raising the chance of losing one of 5 lives; with no lives left the learner waits before going on. Move Mistake chance and Difficulty growth per unit and press Play to see how many units a learner completes.
