## What is Geddit IB?

Geddit is a mastery-based practice app for IB Mathematics (AA HL / AA SL) and AP Calculus BC.

It doesn't count how many questions you did. It checks whether you actually get it:
- Level up on streaks: every concept runs from L1 to mastery; you only advance on consecutive correct answers
- Mistake diagnosis: every wrong option maps to a real misconception and is explained the moment you pick it
- Mistake book: wrong answers are collected automatically and cleared only after three correct retries; clearing one restores 5 energy
- Daily energy: 40 points a day, refilled at midnight, so practice becomes a small daily habit
- Interactive questions: drag on the unit circle, slide a secant toward the tangent, spin a solid of revolution
- Leaderboards: school and inter-school honour boards

Covers every IB AA HL topic, the core AA SL chapters, and the integration part of AP Calculus BC. All questions are written and reviewed by practising IB teachers.

Teachers: build and assign homework, exams and daily check-ins in-app and see class completion and misconception maps in real time. Parents: Parent Mode shows what your child is practising, with a shareable progress card.
