GCSE Physics Tutors in Cambridge: The Subject That Never Stands Alone

Cambridge’s eight state secondary schools enter between 20 and 102 pupils each for separate GCSE Physics, and at every one of them Physics’s own entry count matches either Biology’s or Chemistry’s — it never stands alone as a distinct third figure. Department for Education data for 2024/25 also shows Physics’s own participation rate is never below a school’s published triple-science rate, exactly as the measure’s own mechanics require.

GCSE Physics and Combined Science Are Different Qualifications, Not Different Tiers of the Same One

A parent searching for a GCSE Physics tutor in Cambridge is often really asking about one of two different qualifications, and which one applies changes what a tutor needs to teach. Separate Physics is sat as one of three individual sciences, alongside Biology and Chemistry, each examined and graded on its own on the standard 9 to 1 scale. AQA’s version of the qualification carries the specification code 8463, confirmed directly on AQA’s own GCSE Physics specification page. Pearson Edexcel’s equivalent carries the code 1PH0, confirmed directly against Pearson’s own hosted mark scheme for the qualification; OCR’s Gateway Science version is J249, and OCR’s Twenty First Century Science version is J259 — all four confirmed directly against each exam board’s own qualification pages, not assumed from a list.

Combined Science is a different product, not a shorter Physics course. Pupils on this route study all three sciences — Ofqual’s own guidance on the reformed GCSE sciences confirms that pupils taking combined science “will study all three sciences and they'll cover roughly two thirds of the content of the single GCSEs in biology, chemistry and physics” — but sit it as a single double-award qualification, examined across all three subjects together rather than as three separate paper sets. AQA’s version, Combined Science: Trilogy, carries the code 8464; Edexcel’s is 1SC0; OCR’s Gateway Science version is J250; OCR’s Twenty First Century Science version is J260. The result is not one grade but two: a pupil graded 6-6 has not achieved “a grade 6” the way a separate-sciences pupil would; they have achieved a double award pitched at that level across all three sciences combined, and their results slip carries no Physics GCSE at all.

Physics carries a heavier mathematical load than the other two sciences, and it is not a difference small enough to ignore when planning support. AQA’s own published guidance for its GCSE science exams states plainly: “A minimum of 10% of marks will test mathematical skills in biology; 20% in chemistry; and 30% in physics.” For a pupil sitting the Combined Science double award, Ofqual’s own GCSE Subject Level Conditions and Requirements for Combined Science set a separate rule: no less than 20% of the qualification’s total marks must test mathematical skills, allocated between biology, chemistry and physics in a ratio of 1:2:3. The same document confirms Physics carries two distinct lists of equations: one pupils “must be able to recall and apply”, and a second, given on a sheet inserted into the question papers, that pupils “must be able to select and apply”. Neither Biology nor Chemistry carries an equivalent recall-equations requirement, and a revision plan built for either of the other two sciences will under-prepare a pupil for Physics’s own paper structure.

How Many Cambridge Pupils Actually Sit Separate GCSE Physics?

Department for Education school performance data publishes each Cambridge secondary’s own subject entry numbers — not a rate, but the actual count of pupils entered for each GCSE. Applied to separate GCSE Physics specifically for the 2024/25 cohort, sorted from the highest count to the lowest, and set alongside each school’s Biology and Chemistry entries for comparison:

Five of the eight schools — Parkside, Trumpington, St Bede’s, North Cambridge Academy and Coleridge — enter exactly the same number of pupils for Physics as for Biology and Chemistry; at those five, Physics’s own count is indistinguishable from the other two. At the three schools where the sciences are not entered in equal numbers, Physics never introduces a third, distinct figure of its own: at Cambridge Academy for Science and Technology and The Netherhall School, Physics ties Chemistry’s lower count, 1 and 5 pupils respectively below Biology; at Chesterton Community College, Physics instead ties Biology’s higher count, 1 pupil above Chemistry. Physics is the joint-lowest of the three at two schools and the joint-highest at the third — across Cambridge’s own eight state secondaries, it is never on its own.

Is Physics Ever the Reason a Cambridge School’s Triple-Science Rate Is Lower?

No — not once among Cambridge’s eight state secondaries. Department for Education’s headline measure for this — “entering for biology, chemistry & physics” — reports one combined percentage per school, and the same comparison page publishes, alongside every individual school’s own figure, Cambridgeshire’s own local-authority average and England’s: the county sits at 32.0% of a 6,836-pupil cohort, and England at 23.3% of 625,647 pupils, both repeated identically across each of the eight schools’ own pages because it is the same comparator on every one. Only Cambridge Academy for Science and Technology (98.1%) and Parkside Community College (68.0%) sit above the county average; the other six sit below it, several markedly so.

DfE’s combined measure counts pupils entered for all three sciences together, and because triple-science entry requires a Physics entry, a school’s own Physics participation rate can never fall below its published triple-science rate — the triple-science figure is a floor under Physics, never a ceiling on it. Chesterton Community College shows the gap directly: 80 of its 190-pupil cohort sit Physics, a participation rate of 42.1%, against a published triple-science rate of 41.6% built from its lower, 79-pupil Chemistry entry. St Bede’s Inter-Church School shows the same gap by a different route: it enters 64 pupils apiece for Biology, Chemistry and Physics, a 35.6% Physics participation rate, yet DfE’s own published triple-science rate of 35.0% works out to 63 pupils of its 180-pupil cohort — one fewer than the 64 entered individually for each science, meaning at least one of those 64 Physics entrants did not also sit both Biology and Chemistry. At the other six schools, where the published rate divides out to an exact match with the lowest of the three subject entries, Physics’s own participation rate and the triple-science rate are identical, not merely close.

Why Isn’t Cambridge Academy for Science and Technology a Fifth Comparable School?

Cambridge Academy for Science and Technology’s Physics count looks like the outright winner in the table above, and by raw numbers it is — but CAST is not a fifth comparable data point alongside the other seven, in a way that matters for how a family should read it. CAST is a University Technical College with a STEM specialism, admitting its main cohort at age 13 rather than the age 11 typical of Cambridge’s other seven state secondaries, according to its own Department for Education listing.

CAST’s current Admission Policy sets a Published Admission Number of 104 places for its main Year 9 intake and a minimum of 30 for Year 12 external applicants — but the policy sets no Published Admission Number for Year 10 at all. A family wanting a Year 10 place applies through the Academy’s ordinary in-year admissions process, the same route used for a mid-cycle move into Year 9 or Year 11, rather than a second scheduled intake round. A pupil admitted through the scheduled Year 9 round has had at most three years at CAST before sitting GCSEs, not the five years typical of an age-11 intake at Chesterton or Parkside — but a pupil who joined through in-year admission in Year 10 could have arrived at almost any point in the two years before GCSEs, and no single figure describes how long every such pupil has actually been enrolled.

Amazing tutors!

We arranged maths and English tuition ahead of GCSEs and both tutors were brilliant. My daughter's grades improved, and by results day she achieved two grades higher than in her mock exams.

Great Teaching and Focused Learning

I attended an English bootcamp with Leading Tuition and the experience was excellent. The teacher gave focused attention to the small group while keeping the lessons interactive and engaging.

Where Does Physics Sit in Attainment 8? There’s No Physics Element

A figure quoted for a Cambridge school’s “Attainment 8 Physics element” is describing something that does not exist. Attainment 8 measures a pupil’s average achievement across eight qualification slots, and the Department for Education’s own methodology sets out exactly what they are: “English language; English literature (double weighted providing both English language and English literature are taken); maths (double weighted); three further qualifications that count in the English Baccalaureate (EBacc); and three further qualifications that can be GCSE qualifications.” Science has no dedicated, double-weighted slot the way English and maths do. A Physics result — separate or as part of Combined Science — can only count inside the three EBacc slots, alongside a language and history or geography, or inside the three open slots, never as a slot of its own.

Physics still has a defined route into the EBacc measure, and it works the same way whichever science qualification a pupil sits. The Department for Education’s own EBacc guidance sets out the choice: “GCSE combined science – pupils take 2 GCSEs that cover the 3 main sciences, biology, chemistry and physics” or “3 single sciences at GCSE – pupils choose 3 subjects from biology, chemistry, physics and computer science.” A pupil on the Combined Science route at Coleridge Community College satisfies the EBacc science requirement just as fully as a pupil sitting separate Physics at Cambridge Academy for Science and Technology; the qualification differs, and the mathematical demand differs, as the section above shows, but the EBacc credit for science does not.

None of the figures on this page are Progress 8 scores, because none exist for this cohort. The Department for Education has not calculated Progress 8 — for any school, in any local authority — for the 2024/25 or 2025/26 academic years: “It is not possible to calculate Progress 8 for academic years 2024/25 and 2025/26. This is because there is no KS2 prior attainment data available to use to calculate Progress 8 when the relevant cohorts reach the end of KS4 as primary tests and assessments were cancelled in academic years 2019/20 and 2020/21 due to COVID-19 disruption.” In April 2024 the previous government confirmed there would be no replacement measure for either year. A Progress 8 figure quoted for a Cambridge school in 2025/26 is an older, pre-2024 number, not a current one.

What This Means for Choosing GCSE Physics Support in Cambridge

The entries-based picture above changes what sensible Physics support looks like, and it depends on which of Cambridge’s eight schools a child attends, and on the heavier mathematical demand Physics carries regardless of school. At Coleridge Community College or North Cambridge Academy, where only 20 and 25 pupils respectively sit separate Physics against 86 and 99 on the Combined Science route, the honest planning question is how to cover two exam papers’ worth of biology, chemistry and physics content efficiently, with at least a fifth of the qualification’s total marks across both papers testing mathematical skills — not how to prepare for a third specification almost none of a child’s classmates will sit.

At Cambridge Academy for Science and Technology or Parkside Community College, where 102 and 87 pupils respectively sit separate Physics, a pupil is working to a full, standalone specification in which at least 30% of the marks test mathematical skills, with two distinct lists of equations to master — a materially heavier maths load than either Biology or Chemistry carries on their own papers, even though all three are reported on the same 9-to-1 scale.

Leading Tuition builds a GCSE Physics or Combined Science programme around a child’s own school, specification and current working grade, rather than assuming every Cambridge pupil needs the same balance of physics content and maths fluency. For the exam’s own mechanics in more depth — specification codes across all four boards, grade boundaries and national entry figures — our GCSE Physics results and boundaries guide covers that ground. Our Physics tuition and Chemistry tuition pages set out what a programme looks like for each science, and our guide to 16+ tuition in Cambridge covers what comes after GCSE for a pupil moving on to A-level sciences. If your child is also weighing up other GCSE subjects, our GCSE maths tutors in Cambridge, GCSE Chemistry tutors in Cambridge and GCSE Biology tutors in Cambridge pages cover those subjects in their own right.

Cambridge’s Eight State Secondaries in the Wider County

Cambridge itself is not a separate local authority for education purposes; every one of its eight state secondaries files its Department for Education data under Cambridgeshire County Council, the same authority that also covers a much larger area beyond the city boundary. The same DfE comparison page that publishes each school’s own triple-science rate also publishes Cambridgeshire’s county-wide cohort for the measure: 6,836 pupils reached the end of Key Stage 4 in 2024/25. Cambridge’s own eight state secondaries — Chesterton Community College, Parkside Community College, North Cambridge Academy, Coleridge Community College, Trumpington Community College, St Bede’s Inter-Church School, Cambridge Academy for Science and Technology and The Netherhall School — together account for 1,104 of those 6,836 pupils, or 16.1% of the county’s entire Year 11 cohort; the remaining 84% sit in schools spread across the rest of Cambridgeshire, in towns such as Ely, Huntingdon and Wisbech that are not part of the city itself.

Castle School, Cambridge, sits inside the city itself but is a state-funded special school rather than a mainstream secondary, according to the Department for Education’s own school-search listing, so it falls outside the eight-school comparison on this page.
