GCSE Physics revision covers forces, energy, waves, electricity, magnetism, particle physics, and the structure of the atom. It's the most mathematical of the three sciences — you'll use equations in almost every question. Understanding how to select, substitute, and rearrange equations is the single most important skill for GCSE Physics.
The GCSE Physics exam has two papers. Paper 1 covers energy, electricity, particle model of matter, and atomic structure. Paper 2 covers forces, waves, magnetism, and space physics (AQA only). Each paper is 1 hour 45 minutes. Around 30% of marks are mathematical, which is higher than Biology or Chemistry.
GCSE Physics gives you an equation sheet in the exam, but you still need to know which equation to use, how to rearrange it, and how to substitute values with correct units. The students who score highest are the ones who practise equation work every single day during their GCSE Physics revision. There are 23 equations for AQA — some given, some you must memorise.
- Learn a topic once — don't re-read it endlessly.
- Test yourself on it straight away with quizzes.
- Space it out with flashcards over the following days.
- Practise exam questions against the mark scheme.
Four things that win marks in Physics
GCSE Physics rewards precise recall and clear application. Re-reading notes barely moves either. These four habits target exactly where Physics marks are won and lost.
Build equation fluency — not just recall
Knowing that P = IV is not the same as being able to rearrange it for I when the question asks "what current flows?" AQA alone lists 23 equations — 12 are given on the formula sheet, but 11 must be memorised. The harder problem is rearrangement under pressure. We'd suggest drilling the ones that trip students most often: rearranging v² = u² + 2as for s, rearranging E = QV for Q, and rearranging the wave equation v = fλ for λ when the frequency is buried three lines into a passage. Unit conversion matters too — a question giving speed in km/h and distance in metres will penalise students who don't convert before substituting.
Show every step — Physics rewards method, not just the answer
Physics mark schemes are structured so that a student who makes an arithmetic error but shows correct substitution still picks up the method mark. That mark is lost the moment a student writes only a final number. The habit to build is: write the equation first, substitute the numbers with units, then calculate. In a 6-mark calculation question this can save two or three marks even when the answer is wrong — examiners call this "consequential marking" and it applies on all four boards.
Know what the exam actually asks about required practicals
AQA has 10 required practicals — the most frequently examined in recent papers are specific heat capacity (measuring energy input via E = mcΔT), investigating resistance in series and parallel circuits, the radioactive decay analogy using dice, and waves in a ripple tank. The questions rarely ask students to simply describe the method. They ask for the source of error, how to improve reliability, or how to use the data collected — for instance, how to calculate the specific heat capacity from a gradient on a temperature-against-time graph. Knowing the practical exists is not enough; your child needs to know what the graph looks like and what the slope represents.
Graphs carry more marks than most students expect
A substantial portion of Physics marks across all four boards come from drawing and interpreting graphs — and the mark schemes are unforgiving about scale, labelled axes, and line-of-best-fit technique. The most commonly examined graphs are V-I characteristics (the non-linear curve for a filament lamp is a perennial favourite), velocity-time graphs where the area under the line represents displacement, distance-time graphs where the gradient gives speed, and half-life decay curves where students must read off the half-life from a smooth curve they have drawn. A missed label or a point-to-point line through curved data can cost two marks in under a minute.

How to revise Physics
Consistency beats cramming. A realistic routine — even 20–30 minutes a day — will take you much further than an all-nighter the week before.
Equation practice every single day
GCSE Physics success comes down to equation fluency. Write each equation, practise rearranging it to solve for each variable, then do a calculation. If you can pick up the right equation, rearrange it, substitute values, and convert units in under 2 minutes, you're exam-ready. If not, keep practising. There's no shortcut.
Draw circuit diagrams and force diagrams
Physics is about models, and the best way to learn models is to draw them. Practise drawing series and parallel circuits, free-body force diagrams, ray diagrams for lenses and reflection, and wave diagrams. Being able to draw these from memory is worth 3-5 marks per paper.
Always show your working
In GCSE Physics, working marks are often worth more than the final answer. Write out: equation used, substitution with values, rearrangement, calculation, answer with units. Even if your final number is wrong, you can still get 4 out of 5 marks. Never write just the answer.
Learn to interpret graphs
Graph questions appear on every GCSE Physics paper. Practise calculating gradients (rise/run), reading values from curves, identifying the shape of proportional, inversely proportional, and linear relationships. Know what the gradient represents for velocity-time graphs (acceleration), force-extension graphs (spring constant), and V-I graphs (resistance).
20 minutes a day beats a weekend of cramming
Streaks, XP and a daily plan turn revision into a routine you'll actually keep — the kind that shows up on results day.
Start your streakMistakes to avoid
Most lost revision time comes down to a handful of habits. Steer clear of these and you'll get far more out of every session.
- Using the wrong equation — read the question carefully and identify which quantities you're given and which you need to find before choosing.
- Forgetting to convert units before substituting into equations (g → kg, kJ → J, cm → m, mA → A, kW → W).
- Writing 'the current is used up' in circuit questions — current is CONSERVED. It's energy that's transferred.
- Confusing speed and velocity, or mass and weight. Weight is a force measured in Newtons; mass is measured in kilograms.
- In wave questions, mixing up transverse and longitudinal, or forgetting the wave speed equation v = f × λ.
Revising by year group
Good revision looks different depending on where you are. Pick your year to see exactly where to start and how to build up from there.
Build the foundations before the content gets harder
Year 9 is usually where the formal GCSE course begins — energy, forces, and electricity. Getting these right now pays dividends throughout Year 10 and 11 because every later topic assumes fluency here.
Start with energy stores and transfers — it is the opening unit on every board and the vocabulary (kinetic store, thermal store, work done) underpins everything that follows. If your child can explain why a bouncing ball eventually comes to rest using energy language, they are in the right place.
- 1
Secure the energy unit
Energy stores and transfers, the equation Eₖ = ½mv², gravitational potential energy Eₚ = mgh, and the concept of efficiency as useful output divided by total input. These appear in every board's exam — often in the first question.
- 2
Understand forces and motion
Newton's three laws, resultant forces, the difference between speed and velocity, and how to read a distance-time graph versus a velocity-time graph. This is where many students make mistakes they carry forward for two years.
- 3
Learn the electricity basics
Voltage, current, resistance, Ohm's Law (V = IR), series versus parallel circuits. The conceptual understanding — that current is the same everywhere in a series circuit but splits in a parallel circuit — needs to be solid before your child encounters more complex circuit problems in Year 10.
- 4
Start a formula card
Have your child write every equation they encounter on a single revision card as they go. By the end of Year 9 they should have eight to ten equations on it. The act of writing consolidates memory — and the card becomes a useful diagnostic later.

Your Physics revision journey
The full path from the start of the course to exam day — what to focus on at each stage, and a tip for parents along the way.
Year 10
September — JulyStart GCSE Physics revision by getting comfortable with equations from day one. Every time you learn a new equation in class, practise rearranging it three ways. Year 10 typically covers energy, electricity, and particle model — these topics carry the most marks across both papers. Make sure you understand V=IR, P=IV, and the energy equations before Year 11 starts. Parents: if your child struggles with algebra, this will directly impact Physics — consider extra maths support early.
ParentsAsk your child to write the equation for kinetic energy and rearrange it for mass — if they hesitate, they need more practice on that equation specifically. Do this once a month across Year 10 with a different equation each time. It takes two minutes and tells you more than asking 'how is Physics going?'
Year 11 — Autumn term
September — DecemberYear 11 brings forces, waves, magnetism, and atomic structure. Keep reviewing electricity and energy while learning new topics. Build a master equation sheet with all 23 equations (for AQA), including units and what each variable stands for. Start doing past paper questions by topic — forces and electricity are worth the most marks, so give them the most time in your GCSE Physics revision schedule.
ParentsCheck that your child knows which board they are studying (AQA 8463, Edexcel 1PH0, OCR Gateway J249, or OCR 21st Century J259) — it determines which equations they must memorise and which practicals will be examined. A surprising number of students reaching Year 11 are unsure. The board is printed on every past paper.
6 months before exams
December — JanuaryGo through the entire GCSE Physics specification and honestly assess which topics you understand and which you're guessing at. Spend time on the topics that scare you — for most students, that's electricity circuits, moments, and electromagnetic induction. Practise unit conversions (km to m, kJ to J, mA to A, kW to W) until they're automatic. Examiners give values in awkward units specifically to test this.
ParentsAsk your child to show you their required practicals list and explain one of them — for example, how they measured specific heat capacity in class. If they cannot explain what graph they plotted and what the gradient represented, that practical needs revisiting. Examiners ask about method and analysis, not just results.
Mock exams
January — FebruaryYour Physics mock exam will reveal whether your equation skills are good enough. If you dropped marks on calculations, the fix is practice — not more note-reading. After mocks, sort your mistakes: wrong equation chosen, substitution error, rearrangement error, unit error, or didn't show working. Each has a different fix. Parents: if your child lost marks for 'not showing working', explain that working is worth marks even if the final answer is wrong.
ParentsAfter mock results come back, ask your child to go through the paper and categorise every lost mark as either 'equation error', 'rearrangement error', 'didn't show working', 'graph mistake', or 'content gap'. That categorisation — not the grade — tells you what to fix. Most Physics drops come from the first three, not from unknown content.
3 months before exams
March — AprilDo one full GCSE Physics past paper per week under timed conditions. Practise the 6-mark extended writing questions — these require you to describe or explain a physical process in logical steps, not just list facts. Review all required practicals and know how to evaluate them. Focus on graph skills: reading values, calculating gradients, identifying proportional relationships, and sketching expected shapes for V-I characteristics, cooling curves, and force-extension graphs.
ParentsSet a weekly five-minute test at the kitchen table: pick five equations from the AQA recall list (or your child's board equivalent) and ask them to write the equation, state the units, and do a simple substitution. If they can do all three for all five, move to harder rearrangements. This is not tutoring — it is accountability, which is different and more useful.
Final weeks
May — exam dayIn the final weeks of GCSE Physics revision, do daily equation practice — pick 5 random equations, rearrange each one three ways, then do a calculation with each. Test yourself on required practical methods. Review the topics most students forget: nuclear decay equations, half-life calculations, momentum conservation, and the National Grid (transformers). The night before each paper, read through the equation sheet so there are no surprises.
ParentsCheck that your child is practising graph questions from past papers — not just reading about graphs. Drawing a V-I characteristic by hand, labelling axes correctly, and plotting a curve from given data are skills that need physical practice. Looking at a graph someone else drew is not the same as drawing one under exam conditions.
PrepWise plots this journey for you — a daily plan that adapts to your year and your weak spots.
A note for parents
GCSE Physics is essentially applied maths. If your child is confident with algebra (rearranging formulas, substitution, unit conversion), they'll find Physics manageable. If algebra is a weakness, focus on that first — it's the foundation for 30% of the Physics marks.
You don't need to understand Physics to help. Ask your child to solve a calculation aloud — you'll hear whether they know the method or are guessing. The 'teach-back' technique is powerful: 'explain to me how electricity works in a parallel circuit.'
Buy or print the equation sheet for your child's exam board. Stick it on the fridge. Familiarity with the layout saves time in the exam — students who can find the right equation quickly have more time for the actual question.
Physics past papers are the single best revision resource. They're free on the exam board website. Doing one past paper under timed conditions is worth more than 3 hours of reading notes.
