The curriculum
Eleven tracks, from coin flips to co-location.
Every track is a sequence of short, gamified lessons — concept cards, live code, and quizzes that check you actually got it.
How it works
Built like a game. Rigorous like a desk.
🎯
Learn in 5-minute reps
Each lesson is a stack of swipeable cards. Concept, code, quiz, insight — no 40-minute lectures.
