mathbound

Most contest and exam students grind the same recycled problem sets, get answers handed to them too early, and never systematically fix the mistakes that actually cost points. Mathbound is built for AMC/AIME students first — then SAT, ACT, AP Calc, JEE, and Gaokao — who need real mastery, not another worksheet farm. We solve that with unique mocks (no repeats), Socratic layered hints instead of spoilers, and a spaced error log that forces weak topics back until they stick. Daily workouts, topic lessons, and Elo-rated duels keep practice competitive and measurable. What’s different is that one engine is across contest and standardized tracks, contest-calibrated difficulty, and a path from elite niche prep toward school licensing.
