Learn about Tutor Advantage
The engine
Knowledge Space Theory meets Spaced Repetition.
Two research-backed systems working together: KST maps every skill dependency so the system always knows what's next, and FSRS schedules each review shortly before a student is likely to forget.
Knowledge Space Theory
A directed graph of skill prerequisites. The system knows exactly which skills a student is ready to learn — and which ones they're not ready for yet.
Spaced Repetition (FSRS)
Free Spaced Repetition Scheduler calibrates each review interval to the individual. Items come back shortly before a student is likely to forget them.
Adaptive Placement
Placement uses edge-calibrated assessment to find the level where a student is ready to learn. Adaptive features for Primary Advantage are targeted for May 2027.

For Thai private schools
Built for the constraints you actually have.
Not a Western curriculum bolted onto a Thai schedule. Designed with teacher shortages, large classes, and limited devices as first principles, not afterthoughts.
Blended Learning means printed workbooks plus the digital app, with teacher training. Schools use the same books as families.
Large Classes
Printed workbooks give every student the same structure, in classes of any size
Limited Devices
Blended learning model works with any device-to-student ratio
