For guardians

Everything they need to revise, in one place you can trust.

Sigma Learn gives your child lessons that follow their syllabus, real past papers with honest marking, and help the moment they get stuck. It is free to start; there are no ads, and nothing is sold about them.

Honest marking

They see what an examiner would see.

Answers are marked against the real mark scheme, point by point. A wrong answer comes with the reason and the solution — so a mistake becomes the next thing to practise, not a guess at what went wrong.

  • Marks shown per marking point, with the mark scheme alongside
  • Wrong answers can be filtered and retried until they are right
  • Points and streaks reward steady work, not cramming
What it costs

Free to start. Pro is optional.

Every past paper and interactive is free, and so is the first 60% of every course. Pro opens the rest of the lessons and adds AI that works without setting up a key.

Following their progress

Progress you can see together.

Progress reports for guardians are still being built. Until they are ready, the simplest way to see how your child is doing is to look at their question bank together: every paper shows what was right, partly right and wrong, and every course shows which lessons are done.

Can a guardian see their child’s progress?
Progress reports are still being built. Until then, the simplest way is to look at their question bank together: every paper shows what was right, partly right and wrong. See for guardians.
What do you store about me?

What is sent to the AI?
When you use Ask AI or AI marking, your question or answer and the lesson or question it is about are sent to Anthropic’s Claude to produce the reply.
Can I delete my data?
You can reset your learning data yourself in Settings. To delete the account itself, contact us and an administrator will remove it.
