Free mastery-based courseware that Khanmigo sits on top of

The Four Mismatches · Khan Academy

Built for another system

Assessed for a Commonwealth / Global-South student (as an import).

  • CurriculumFail

    Built to US Common Core and AP, not to local exam boards like SPM, WAEC or the CBSE boards.

  • LanguageFail

    English-only for the core courseware.

  • PricePass

    Genuinely free and non-profit — the price axis is no barrier at all.

  • InfrastructurePartial

    Web and app; needs a connection, with no full offline mode.

Free and genuinely excellent — but a US curriculum in English, so product-export for a local exam. Its free price is its strongest axis.

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.

The fit assessment

The scorecard above scores Khan Academy on the four axes on which exported EdTech fails to fit a local system — assessed for a Commonwealth / Global-South student (as an import). The verdict: Free and genuinely excellent — but a US curriculum in English, so product-export for a local exam. Its free price is its strongest axis. For the full framework, see the Four Mismatches Test.
