Terms of use
Learning content
The games, lessons, guides, worksheets and tools on this site are general learning material. They support, and do not replace, a school, a teacher or an official exam board. For exams, follow your own syllabus and the official sources linked on each page. Syllabi, formats and dates can change.
No guarantees
We do not promise marks, ranks, grades, places, certificates, jobs or income. Results depend on the learner, the time spent and the exam or event.
Learner accounts
A learner account is free. A parent or guardian must create it for anyone under 13, and is responsible for what is entered in it. Use a real email address, a first name or nickname and a password only you know. Please do not share your account. You can download or delete your account and its progress at any time from the My learning page. We may close an account that is used to send spam, to attack the site or to harm others.
Live classes
We confirm the teacher, format, time zone, availability and price with a parent or guardian before anything is booked. Any paid class is priced and agreed before it starts.
Software projects
We agree the scope and the price in writing before paid work starts. You keep your accounts, domain and content.
Using the site
Please do not copy the site at scale, probe it for weaknesses or use automated tools to sign up. Games and tools run in your browser, and scores are saved in your own browser unless you have an account.
Trademarks
Names such as Rubik's Cube, Python and the names of exams and exam boards belong to their owners. We use them only to describe what we teach and are not affiliated with them.
