Choose your track
Each track is a ladder of levels: take the placement test to find your starting point, then climb level by level — every lesson passed unlocks the next.

Frequently asked questions
Are the courses really free?+
Yes. All series, video classes and quizzes are free, with no account or signup required. Progress is saved automatically in your browser.
What is “immersive classroom mode”?+
In immersive tracks, the class plays like a real lesson: the video cannot be fast-forwarded (rewinding is allowed), and the quiz runs on a timer. It keeps learners focused and makes sure the material is actually watched.
Which track should I start with?+
Take the free placement test on any track — it finds your level and unlocks the right starting point. Without a test, every track starts from its first level.
Why are later lessons locked?+
Each lesson builds on the previous one, so the next lesson unlocks when you score 80% or more on the current quiz. Quizzes can be retaken as many times as needed.
Where do the videos come from?+
Classes embed kid-friendly teaching videos from YouTube channels using YouTube's standard embed player, wrapped in our classroom controls.
Will we lose our progress?+
Progress is stored in your browser (localStorage). It persists between visits on the same device and browser, but clearing site data or switching devices resets it.
