FAQ
Catalog questions
What is in the catalog?
Everything a learner can do here: 477 paths, courses, lessons, skills to practise, games, Python programs, maths topics, cube algorithms, guides, tools and live classes.
Is it free?
Everything except the live classes is free and needs no account. Live classes are taught by a teacher and are paid; the price is agreed before you book.
How do I find the right level?
Use the Level filter, and the age shown on each card. Beginner suits younger learners or anyone new to a topic; Advanced suits older learners and exam preparation.
How is it sorted?
By default, the longest guided series first (paths and courses), then lessons, skills and games. You can also sort by shortest time or by name.
