PREPARE FOR EXAMS

Revision that adapts

Choose Paper 1, Paper 2 or both, repair mistakes, focus on a skill and practise timed exam sections.

Explore Revision and Exam Coach

For individual learners

A structured Computer Science study tutor, available whenever you are.

Learn an unfamiliar topic, test a piece of Python, complete ten minutes of retrieval or repair a recent mistake. Computing Covered connects explanation, practice, feedback and later revision instead of sending students between unrelated websites.

Built around how learning sticks

Understand, retrieve, apply, improve and revisit.

Clear explanations and worked examples introduce an idea. Retrieval brings earlier learning back. Students then apply it in code, diagrams, data and exam questions, receive useful feedback and revisit weaker areas after a gap.

See how the learning design works
  1. 1. Understand

    Student-friendly explanations, diagrams and worked examples reduce unnecessary confusion.

  2. 2. Retrieve

    Short recall prompts strengthen important knowledge instead of only rereading it.

  3. 3. Apply

    Students write, trace, build, calculate and explain rather than passively clicking through.

  4. 4. Improve

    Instant checks, progressive hints and later revisits turn errors into the next learning step.
