How extras work

  • Chosen per school

    Primary extras come with KS1 or KS2, Secondary extras with KS3. Pick neither, one or both when you ask for a quote.

  • Part of the same login

    Pupils see extras as more subjects next to their maths, with the same marking, progress and mistakes to retry.

  • Homework or free practice

    Teachers can set extras as homework like any other subject, or leave them for pupils to explore.
