Type anything. The videos come back in order: level one first, each one picking up where the last stopped.
You watched it. Can you explain it?
Short videos on one skill, in order - then a small task, and you explain it in your own words.
Courses are assembled automatically. Each course page says whether anyone with subject knowledge has read it, and the record is for you, not a certificate.

Catalogue counts, not people.
Watch, in order
Short clips only; long talks are cut to the part that teaches. A quiz is written for each section, and when it cannot be written the page says so rather than pretending the section is empty.
Explain it out loud
Thirty seconds, in your own words. A progress bar fills itself if you leave a tab open; an explanation is at least something you had to produce.
Questions people ask
Does it cost anything?
No. There is no payment of any kind, and nothing is behind a wall.
Whose videos are these?
They belong to the people who made them. Every lesson plays from YouTube or TikTok in their own player, with a link back to the original, and the views count on their side. Nothing is downloaded or re-hosted.
Do I need an account?
No. Progress is kept against a key stored in this browser. An account exists so that history follows you to another device, and signing in carries what you already did across.
What happens to my recording?
It is sent to a speech-to-text service and comes back as text. Only the text is stored: there is no audio column in the database and no file store behind it.
Does good feedback mean I have learned it?
It means you explained it well enough for a reader to follow. That is worth far more than a video finishing, and it is still not the same as the work. The task at the end of each section is the part that checks the work.
Watching is not learning. Explaining is.
Minutes watched is the easiest thing to measure and the easiest to fill without learning anything. What is measured here is what cannot be done passively: whether you can say it back.
