Remelia and this exam

What Remelia covers, and what it does not.

Choose the school when you set your child up, or later in Controls, and this is the plan.

What Remelia covers

Key Stage 2 maths and English to Year 6, counted towards the exam.

  • Maths

    The Key Stage 2 objectives for Years 3 to 6, in the order your child’s school teaches them, counted towards the exam.

  • English

    Grammar, punctuation, spelling and vocabulary questions most days, Years 3 to 6, counted towards the exam.

  • Reading

    From the autumn of Year 5, a weekly reading day: one unseen passage and 9 questions on it, from a bank of 130 passages.

  • The last fortnight

    In the last 14 days before the exam date the plan works to, sessions are shorter and nothing new is introduced. The plan works to November of Year 6; until the school publishes the day for your child’s year, that date is an estimate.

Not covered

Verbal reasoning, non-verbal reasoning, the interview and the test’s own format.

  • Verbal reasoning

    Remelia does not teach verbal reasoning.

  • Non-verbal reasoning

    Remelia does not teach non-verbal reasoning.

  • The interview

    A conversation with the school, which an app cannot practise.

  • The test itself

    Remelia practises the content, not the ISEB Common Pre-Test’s own screens, papers or timings: the familiarisation materials, where there are any, show those.

  • Printable English papers

    The printable practice papers in the parents’ app are maths only.
