Questions
Do I need math?
No. Every lesson explains the idea with pictures and narration first. Where math helps, it comes after the picture and you can skip it.
What is free?
The first section of every lesson is free for everyone, no account needed (some lessons have more free sections). A subscription unlocks every section, the hands-on labs, the quizzes and your score history.
How do classrooms work?
A teacher creates a virtual classroom and adds students, or gives them a join code. Students need no email address. The teacher sees every student's progress and quiz scores in one grid.
Can I cancel?
Yes, at any time. You keep access until the end of the period you paid for.
Do you track me or show ads?
No. The whole site has no advertising and no third-party tracking, for every visitor and every account.
What about student privacy?
Like every account, student accounts are never tracked and never see ads. On top of that, students need no email address, and the teacher who created a student's account controls it and can delete the student and all of their data.
