How to revise Physics: the best ways to improve at GCSE and A Level

The best way to revise Physics is to repeat a short cycle: diagnose a precise weakness, retrieve the relevant knowledge from memory, apply it to a question, get feedback, correct the cause of the mistake and revisit it later. This combines active recall with problem solving and stops revision becoming a tour of things you already know. Good revision is not about doing the most work; it is about repeatedly identifying what you cannot yet do and fixing it.

Physics needs several skills at the same time. A pupil may know the facts but choose the wrong equation; calculate accurately but omit the unit; or understand the idea but fail to build a clear written explanation. That is why a single label such as “good at electricity” tells you very little.

Why these methods? A major review rated practice testing and distributed practice as high-utility learning techniques across a broad range of learners and tasks. The review did not say that every form of testing, spacing or interleaving works equally well, so the practical details below matter. Read Dunlosky and colleagues’ 2013 review.

Start Physics revision with evidence, not a favourite topic. Use the specification, recent tests and short diagnostic questions to locate precise things you cannot yet recall, explain or apply.

A topic checklist is useful, but “red, amber, green” can become guesswork if it is based on confidence. Test each judgement. Can you state the definition without notes? Can you select the relationship in an unlabelled question? Can you explain the result? Can you still do it a week later?

For AQA GCSE Physics and Combined Science, AQA A Level Physics or OCR A Level Physics A, keep the correct specification open while you build the list. A question bank tells you what has been asked; the specification tells you what may be assessed.

Active recall means trying to produce an answer before seeing it. It is especially useful for equations, definitions, laws, units, practical knowledge and key relationships.

Rereading can make a page feel familiar, but recognition is not the same task as producing an answer in an exam. Close the book, answer, then check. If you cannot retrieve it accurately, you have found useful work.

Flashcards are useful when the prompt demands a real response. A card that says “read this equation” is passive; a card that asks you to recall, interpret and apply it is active. Short A Level Physics MCQ practice can also expose misconceptions, but follow it with questions that require working and explanation.

Retrieval is not merely a way to measure memory. In a well-known experiment, repeated testing improved delayed recall more than repeated studying once items had been learned. The material was vocabulary rather than school Physics, so it supports the retrieval principle rather than proving a particular Physics routine. Read Karpicke and Roediger’s study in Science.

Move from worked examples to unsupported questions. Examples can teach a method, but improvement is demonstrated when you can choose and carry out that method without copying the steps.

If a topic is new, study one good worked example and explain why each step is there. Then cover it and try a similar problem. Reduce the support until you can complete a fresh question alone. Guidance on science teaching recommends worked examples, fading and alternating examples with problems rather than leaving novices to guess a method indefinitely. See the EEF secondary science guidance.

1. Identify quantities.Write what is given and what the question wants, using symbols where helpful.
2. Convert units.Deal with prefixes, minutes, centimetres, electronvolts or other conversions before substitution.
3. Choose the Physics.Select the model, principle or relationship; do not start by hunting for any equation containing the same letters.
4. Rearrange.Make the required quantity the subject before inserting numbers when that keeps the algebra clearer.
5. Calculate.Show substitution and keep enough figures during intermediate steps.
6. Add the unit.Make sure the unit belongs to the quantity you calculated.
7. Sense-check.Check sign, direction, order of magnitude, limiting behaviour and physical plausibility.

For more deliberate calculation practice, use A Level Physics problem-solving questions or the free ProblemBOT preview. Keep all working visible: a wrong final number can still reveal a correct model, or expose exactly where the method failed.

Mix question types so that you must decide which Physics applies. Twenty nearly identical questions can improve execution while hiding a weakness in method selection.

A worksheet headed “kinetic energy calculations” has already made the hardest decision for you. Real papers move between energy, momentum, circuits, graphs and practical data without announcing the technique. Once you can complete a blocked set accurately, mix it with previously learned material.

In an undergraduate Physics study, interleaved homework improved memory and problem-solving performance and appeared to give learners more practice in strategy selection. It is promising evidence, not a guarantee that every shuffled worksheet helps every GCSE or A Level pupil; mix questions after the underlying methods have been taught. Read the open-access physics study.

Do not retire a weakness because you answered correctly immediately after reading the solution. Reattempt it after a delay, preferably with a different question that tests the same idea.

Immediately after feedback, the method is still in working memory and the question is familiar. A later attempt asks whether you can retrieve and transfer the learning. There is no perfect fixed spacing schedule for every pupil and every topic. A practical approach is to revisit a new correction after a few days, then again after a longer gap if it remains fragile.

Keep the revisit small: one definition, one calculation and one explanation can be enough. Correct answers move to a longer interval; repeated errors return to diagnosis. This is distributed practice in a usable form, not a demand to rebuild your entire timetable around an app.

Strong Physics explanations connect a cause to a consequence. Practise calculations and written answers every week; being comfortable with formulae does not automatically produce clear reasoning.

Build a chain rather than a pile of keywords. A useful rehearsal frame is:

For example: Because the resistance increases while the supply potential difference is constant, the current decreases. Therefore the power transferred by the component decreases, so less energy is transferred each second. The linking words are scaffolding, not mandatory exam vocabulary. The Physics on each side of them must be correct.

After writing, underline the cause, the link and the requested conclusion. If one is absent, edit the answer. Use A Level Physics QWC practice questions or the free written-explanation practice to make this a normal part of revision.

A quick, labelled diagram can turn words into a model you can reason with. Draw it before choosing equations when direction, geometry, components, paths or energy levels matter.

• Force diagrams: isolate one object, draw forces from the object and label direction and type.
• Fields: show direction, relative spacing and the source; do not confuse a field line with a particle path.
• Circuits: redraw an awkward arrangement and mark known current and potential difference information.
• Rays: add the normal, directions and relevant angles.
• Vectors: choose a scale or resolve components consistently.
• Waves: mark equilibrium, amplitude, wavelength and phase points where relevant.
• Energy-level diagrams: show permitted levels and label the direction of transitions.

The diagram is working, not artwork. It should reduce ambiguity. If it adds assumptions the question did not make, it can lead you in the wrong direction, so label only what the physics supports.

Revise practicals as decisions, measurements and evidence—not as scripts to memorise. You need to explain why a method works, how data should be treated and whether the conclusion is justified.

A vague improvement such as “use better equipment” rarely shows enough thinking. Say what would be changed, what would be measured more precisely and why that matters. Official specifications make clear that practical work includes planning, variables, data presentation, graphs, uncertainty and evaluation: see AQA GCSE Physics practical assessment, AQA A Level Physics practical assessment and the OCR A H556 specification.

Past papers are valuable, but a full timed paper is not always the best first step. Match the format to your stage of revision, then spend serious time analysing the attempt.

After every paper, separate “I lost five marks” into causes. Which topic? Which skill? Was it a knowledge gap, equation choice, maths, unit, explanation, practical skill or instruction error? Correct it, find one fresh follow-up question and schedule a later revisit. Avoid memorising a mark-scheme phrase without understanding when it applies.

Use your exam board for the authoritative documents and current assessment information: AQA GCSE Physics 8463, AQA A Level Physics 7408 and OCR A Level Physics A H556.

In 30 minutes, include retrieval, a known weakness, independent questions, diagnosis and a planned revisit. The timings below are a starting structure, not a rule.

1. 0–5 min

   Retrieval

   From memory, write two equations, one definition and one diagram from a previous topic.

2. 5–10 min

   Revisit a weakness

   Reattempt one item from your error log without looking at the old solution.

3. 10–23 min

   Problem solving

   Complete two or three exam-style questions independently. Include at least one that makes you choose the method.

4. 23–27 min

   Mark and diagnose

   Use the solution or feedback, then label the cause of every lost mark.

5. 27–30 min

   Correct and plan

   Write the corrected reasoning and record the exact task to revisit, with a date.

If the marking reveals a substantial misconception, stop. It is better to correct one important idea than rush through another question to complete the timetable.
