Assessed for a Chinese K-12 student (its home market).

Built for the Chinese compulsory curriculum and gaokao track.
- LanguagePass
Mandarin-native.
- PricePartial
Tuition through physical learning centres; not streaming-subscription cheap.

System-native to China — and shaped by a market walled off by language and the 2021 Double Reduction policy.
addestra.com · The Four Mismatches Test. A single fail means it was built for a different system.
Independence: Addestra builds learning products too (MathsTutor, TinkerWell). We never review or score our own, and no tool pays to be listed or to rank higher — how we assess fit.
What it does
What the AI actually does — An adaptive knowledge-tracing engine that decomposes subjects into fine-grained 'knowledge points' (10,000+ for middle-school maths) and routes each student individually.
Why it was built — Replace generic exam tutoring with 1-on-1 personalised learning paths at scale, delivered through offline centres.

The fit assessment
