How to resit GCSE physics

If you're resitting GCSE physics, you're not on your own. Physics is the most maths-heavy of the three sciences, and a lot of students who resit do so because their maths let them down, not because they didn't understand the physics. Knowing that changes what you actually revise.

This guide walks through tier choice, paper structure, where the equation sheet stands for 2026, and how to plan around the one fact that shapes the whole timeline: physics is summer only.

Per the Joint Council for Qualifications (JCQ) timetable, the only GCSE subjects available in the November series are English language and maths. Everything else, sciences included, is summer-only.

In plain terms, if you sat physics in summer 2026 and want to resit, your next sitting is summer 2027. There's no quick re-do in November or January. That's a long runway, which means a routine you can keep up across nine months matters more than a short, intense burst that you'll abandon by February.

GCSE physics is sat at one of two tiers. Foundation covers grades 1 to 5. Higher covers grades 4 to 9. The grade 4 pass is available on both, which is what matters for most resitters.

If you sat higher and walked away with a grade 3, switching to foundation is the move most teachers would suggest. The paper has less of the harder content (no paper 2 space physics, no nastier-form kinetic energy or specific heat capacity questions), and the grade 4 threshold sits near the top of the foundation paper rather than the bottom of the higher one.

The ceiling on foundation is a grade 5. If you reckon you could realistically push for a 6, stay on higher. For students who got a 3, that's usually wishful thinking. A confident 4 on foundation beats a near-miss on higher. If you got a 2 or below, foundation is the only sensible option.

GCSE physics is two papers. Per AQA's specification (broadly the same for Edexcel and OCR), each paper is 1 hour 45 minutes and worth 100 marks at separate-sciences level. Combined science physics papers are shorter at 1 hour 15 minutes and 70 marks each, but the topic split is the same idea.

Space physics is paper 2 content and isn't assessed at foundation, so if you're switching down, that's one topic to park. Magnetism and electromagnetism is what most students find unfamiliar on paper 2, and forces (especially the maths-heavy bits like resultant forces and momentum) is where a lot of marks get lost.

This is the big change worth knowing about. For the 2026 series, both AQA papers include a printed equation sheet as an insert. Ofqual extended the equation sheet concession through 2026 and 2027 (originally a one-off post-pandemic measure), so every equation you need is in front of you in the exam.

In practice: you don't have to memorise the list. You do still have to know what each equation is for, which letter is which quantity, what the units are, and when to reach for it. Knowing that F equals ma doesn't help if you can't spot a force question when you see one.

After 2027, AQA returns to the normal split, where a handful of equations (density, wave speed, the energy equations) need to be memorised. For a 2026 or 2027 resit, treat the whole list as given and put your time into using the equations rather than reciting them.

Around 30 percent of marks on GCSE physics are awarded for maths skills, per Ofqual's minimum requirements. That's the highest of the three sciences. If your last paper went badly, there's a real chance it wasn't the physics that caught you out. It was the rearranging, the unit conversions, the standard form, or basic number work under pressure.

A quick test: can you, without a calculator, work out 0.4 multiplied by 250? Convert 2.5 kilometres into metres? Express 0.0034 in standard form? Rearrange v = u + at to make a the subject? If any of those felt shaky, that's where to start.

Spending the first month of resit prep on the maths skills underneath the physics, then moving onto topic-by-topic work, pays off everywhere across both papers.

AQA GCSE physics has 10 required practicals at separate-sciences level. You don't redo them as a separate exam. They're assessed through written questions on papers 1 and 2, asking you to describe a method, identify equipment, explain a control variable, or interpret results.

The ones that come up most often are specific heat capacity, resistance of a wire, density of solids and liquids, acceleration and force, and waves on a string. For each, you want to be able to talk through what you measured, what you kept constant, and what the main source of error was.

If you can't get hold of lab equipment, reading the method and writing a one-paragraph summary in your own words is enough for the written questions.

If you're at sixth form or college and physics is a condition of your course (less common than the maths or English condition of funding rule, but it happens for science A-Levels and some BTECs), your provider will usually enter you. Most further education colleges focus their resit support on maths and English (the subjects covered by the Department for Education's condition of funding rule), so physics provision outside school is harder to come by.

In practice, your routes are going back to your old school as an external candidate (sometimes possible), or sitting as a private candidate at a private exam centre. Private centres charge an entry fee on top of the exam fee. Looking at published rates across centres, you're typically looking at £40 to £80 per paper plus an administration fee of £80 to £150 per subject. Two papers means roughly £160 to £310 all in. Ring two or three centres for quotes, the fees vary a lot.
