Self-study a complete, mastery-based curriculum from counting to calculus — sequenced worksheets, grid games, and progress you can see. Built on the science of the s-curve.
A full curriculum
Sequenced worksheets from counting to calculus, unlocked as you master each skill.
Mastery, not minutes
Advance when you actually own a skill — measured by speed + accuracy, not time spent.
Practice that feels like a game
Grid puzzles and daily challenges build fluency without the grind.
See your progress
Streaks, XP, ranks and analytics show exactly where you are on the curve.
From counting to calculus, one level at a time.
How mastery is measured
Every level has a target range — not just an answer key. Progression is earned, not granted.
Accuracy threshold
Each booklet tracks correctness across every problem. 90% accuracy is required before the next level unlocks.
Standardised Completion Time
SCT is the target window of completion time per booklet. Finish inside the window and the skill is marked fluent, not just completed.
Gold-level mastery
Beat the fast SCT range for bonus XP and a gold mastery badge. Real rewards for real fluency.
How it works
