This lesson checks which CS1–CS9 topics need attention before Tuesday’s test. Everything pupils need is on this page: the diagnostic marks itself, the results send each pupil to the right lesson, and model answers support the later practice. Please supervise the running order rather than teaching the content.
| Clock | What all pupils do |
|---|---|
| 0:00–0:20 | Diagnostic Quiz — work silently and submit once. |
| 0:20–1:50 | Targeted Review + Drill — start with red, then amber. Quiet pair discussion is fine when pupils are reviewing the same topic. |
| 1:50–2:00 | Wrap up — complete the mixed section if ready, then print/export or note the red and amber topics for home revision. |
Answer every question without notes. Your choices save automatically. Select Mark my diagnostic when finished to build your personal review route.
Use precise N5 terminology. Write enough separate points for the number of marks shown, then reveal the model answer.
Purpose: this is a low-stakes readiness check, not a second test. The traffic lights are green = all correct, amber = at least half correct, red = below half.
Question-to-content map: diagnostic questions 1–4 cover data representation calculations and concepts; 5–8 cover graphics/sound calculations and quality; 9–13 cover processor, buses and memory; 14–18 cover storage and translators; 19–20 cover environmental impact and security. The mixed practice uses typical 1–3 mark command words: state, describe, explain and justify.
Review after the lesson: ask all pupils to print/export or record their traffic-light grid. A cluster of red results in Computer Structure or Translators is a useful signal for whole-class retrieval practice before the test.
