Final GCSE Physics exam routine

Use a calm final routine for equations, units, graphs, required practicals and explanation questions.

Qualification: GCSE Subject: Physics Exam routine Separate Physics and Combined Science

Exam technique

This lesson builds physics exam technique and mixed-question checking for GCSE Physics.

Use the core lesson first, then match the exam-board guidance to your school route. Many pupils meet this content through Combined Science as well as Separate Physics.

Mixed exam routine prompts supplied on this page

Use the mixed calculation, graph, practical and explanation prompts to practise the routine before moving to past papers.

Clear explanation

Physics exams reward clear method. Before calculating, identify the quantity asked for, list the values given and choose the equation that connects them.

For explanations, use a chain: cause, physics model, result. For practicals, name variables, measurements, controls, repeats and uncertainties.

For graphs, read the axes first. Gradient and area often have physical meaning, but only after you know what each axis shows.

Key graph

Velocity-time graph exam check A velocity-time graph has a sloping section followed by a horizontal section; the gradient is acceleration and the area under both sections is distance. time / s velocity / m/s gradient area
Graph: read axes first, then decide whether the question needs gradient, area or a direct value.

Worked examples

Turning a weak explanation into a physics answer

Weak answer: the car stops because brakes work.

Better answer: braking creates a resultant force opposite the motion, so the car decelerates and kinetic energy is transferred to thermal stores.

The better answer names force, motion change and energy transfer.

Answer: A strong answer links the cause to the physics model and the observed result.

Quick checks

Choose an answer, then check your thinking.

1. What should you do before choosing an equation?

2. What should you read first on a graph question?

Practice questions

Question 1

A question gives mass, specific heat capacity and temperature change. What equation family should you consider?

Reveal answer and marking guidance

Answer: Energy = mass x specific heat capacity x temperature change.

Marking: Credit recognising the heating equation from the quantities.

Question 2

A practical asks how to improve reliability. Name one useful answer.

Reveal answer and marking guidance

Answer: Repeat readings and calculate a mean, after checking for anomalies.

Marking: Credit repeats linked to reliability and anomalies.

Question 3

A graph has velocity on the vertical axis and time on the horizontal axis. What does area under the graph represent?

Reveal answer and marking guidance

Answer: Distance travelled.

Marking: Credit velocity x time gives distance.

Question 4

What three things make a strong physics explanation?

Reveal answer and marking guidance

Answer: A cause, the correct physics model and the result or evidence.

Marking: Credit cause-model-result structure.

AO1 fluencyRecall the key definition, unit, equation or model before using the lesson questions.
AO2 applicationApply physics exam technique and mixed-question checking to an unfamiliar device, practical setup or data description.
AO3 analysisUse evidence, graph features, uncertainty, method quality or conclusion wording where the question asks you to evaluate.

Answers and marking guidance

The exact practice answers are hidden under each question so you can try first. For this lesson, marks come from using the correct physics model, choosing the right equation where needed, keeping units with values, and explaining changes with precise words such as transfer, resultant force, acceleration, evidence and uncertainty.

Common mistakes

  • Starting calculations before identifying the quantity.
  • Leaving units off final answers.
  • Using memorised wording without linking to the question context.
  • Treating every practical improvement as simply 'repeat it' without saying why.

Exam-board guidance

All supported routes assess the core physics idea, but they may group topics, practicals and paper wording differently.

AQA GCSE Physics

AQA GCSE Physics: use this lesson for physics exam technique and mixed-question checking, then check whether your class is taking Separate Physics or Combined Science.

OCR GCSE Physics

OCR GCSE Physics: the core physics idea is shared, but Gateway and Twenty First Century may organise questions differently.

Pearson Edexcel GCSE Physics

Pearson Edexcel GCSE Physics: practise the concept, the equation use and the practical language because questions often connect them.

Eduqas GCSE Physics

Eduqas GCSE Physics: learn the core explanation and practise applying it to unfamiliar contexts, data and practical questions.

WJEC Wales

WJEC Wales: check whether your class is using the current GCSE Physics route or a newer science route, then use this lesson for the shared physics idea.

CCEA GCSE Physics

CCEA GCSE Physics: connect the idea to your unit and remember that practical skills are assessed directly.

Extension challenge

Take one past-paper physics question and annotate it with quantity asked, values given, equation, unit check and final reasonableness check.

Reveal answer

Example answer: A strong extension response names the physics model, uses accurate units and explains why the evidence supports the conclusion.
