Prerequisite Chains
Energy (stores, transfers, conservation) ├── Forces (work, power, kinetic/potential energy) └── Electricity (energy transfer, power calculations)
Forces (Newton's laws, mass, weight) ├── Energy (work, gravitational potential energy) └── Waves (wave speed formula)
Electricity (current, voltage, resistance) ├── Energy (power, energy calculations) └── Magnetism (electromagnetic induction, transformers)
Waves (wave properties, speed, frequency) └── Magnetism (electromagnetic waves)Recommended order of diagnostic completion:
diag-energy— foundational concept of energy conservationdiag-forces— Newton’s laws, a core physics toolkitdiag-electricity— circuit analysis and Ohm’s lawdiag-waves— wave properties and the EM spectrumdiag-magnetism— builds on electricity concepts
Timing Recommendations
| Diagnostic | Recommended Time | Notes |
|---|---|---|
diag-energy | 35 minutes | Includes specific heat capacity calculations |
diag-forces | 40 minutes | Multi-step Newton’s law problems |
diag-electricity | 40 minutes | Circuit analysis requires careful working |
diag-waves | 30 minutes | Mix of recall and calculation |
diag-magnetism | 35 minutes | Induction problems can be complex |
Total recommended time: approximately 3 hours (spread across 2 sessions).
How to Use These Diagnostics
- Complete each diagnostic without notes, showing all working.
- Always include units in intermediate and final answers.
- Draw diagrams for circuit problems, force diagrams, and wave diagrams.
- Check solutions immediately, comparing method and answer.
- If you score FAIL, review the source file before retrying.
- Integration Tests frequently combine topics (e.g., energy and forces, electricity and magnetism) — these mirror the style of GCSE combined questions.
- Practise writing explanations in full sentences, as GCSE Physics awards marks for descriptive answers.

Common Pitfalls
- Confusing terminology or concepts that appear similar but have distinct meanings.
- Overlooking key assumptions or boundary conditions that limit applicability.
