How to Revise for GCSE Physics
GCSE Physics is the most formula-driven science. Learn every equation, master rearranging them, and practise calculation questions until units and substitutions are automatic.
A realistic weekly plan
- 1× 30-minute formula recall (write all equations from memory).
- 2× 40-minute calculation drills (energy, forces, waves, electricity).
- 1× 45-minute required-practical review (circuits, springs, waves).
- 1× 30-minute extended-answer practice with a mark scheme.
Techniques that actually work
Equation triangles for rearranging
For each formula (V=IR, F=ma, P=W/t) draw the triangle. Within 2 weeks you'll rearrange instinctively under exam pressure.
Always quote the equation first
Write the formula → substitute values → calculate → state units. Each step often carries a mark, even if your final answer is wrong.
Units, units, units
Joules vs kilojoules, metres vs centimetres, seconds vs minutes. Convert at the start of the question, not the end.
Common pitfalls to avoid
- Confusing scalar and vector quantities.
- Forgetting to square velocity in kinetic energy (½mv²).
- Mixing series and parallel circuit rules.

Frequently asked questions
Do I need to memorise every Physics equation?
AQA gives you some on a sheet, Edexcel gives fewer, and you must memorise the rest. Check your exam board's specification — a typical list has 20–25 equations to learn.
How do I tackle 6-mark Physics questions?
Identify the physics principle, state the relevant equation or law, then apply it to the scenario step-by-step. Use technical vocabulary (conservation, gradient, terminal velocity).
Which topics carry the most marks?
Energy, electricity, and forces dominate Paper 1. Waves, magnetism, and particle model dominate Paper 2. Don't neglect either.
