# Units

> Online Ontario high school credits on a mastery-based platform: interactive lessons, OCT-certified support, an AI learning coach (Gilbert), three-layer assessment (create → defend → critique), and official OSSD credits issued through accredited school partners at $1,000 per credit.

Units is built for motivated Ontario students who want to finish credits faster without sacrificing rigor. Public marketing pages and individual course detail pages are crawlable; the signed-in learning app under `/learn` (except `/learn/courses/{slug}`) requires authentication.
