Workout Setup
Select a topic, difficulty, and target reps to start a session.
1 rep = 1 unique problem; 1 set of 2 reps = 2 unique problems; 2 sets × 3 reps = 6 unique problems. If a solution fails the tests, you're still on the same rep until it passes — then the workout advances to the next rep or set.
