We don’t pretend our tutor is magic. Every age-appropriate answer is built on published, citable curriculum sources, and every practice question is checked by independent reviewers before a child ever sees it. This page shows exactly what we cover and where it all comes from.

The official English National Curriculum, KS1 to KS4. The same documents every state-school teacher is required to follow.
A government-backed library of teacher-made lessons, freely licensed for educational use, covering the full English curriculum.
Real Year 6 SATs papers, with mark schemes — used as a reference so practice questions match the style and difficulty children will actually meet in the exam.
Practice questions written by AI, grounded in the curriculum sources above. Every question is then checked by two separate AIs — for accuracy, for the right level for the child’s year group, and for whether it teaches the topic well. Anything they disagree on is held back for a human to look at.
Active practice questions per subject × year group. Empty cells are on the roadmap, not gaps in the curriculum itself.

well covered some questions thin · no questions yet
Practice questions don’t reach a child until at least two separate AIs have checked them — for accuracy, for the right level for the child’s year, and for whether they teach the topic well. Anything those two AIs disagree on is held back for a human to look at.

Each reviewer is a separate AI. When two reviewers disagree, a human takes a look before the question goes live. We use whichever AI tools are best for the job today; we’ll switch as better ones become available.
