AQA and OCR both offer widely taken A-level Physics specifications. AQA (7408) is the most popular nationwide; OCR offers Physics A (H557) and the context-driven Advancing Physics B (H558). Both lead to the same university doors, but their teaching approaches and paper styles differ considerably.
How is AQA A-level Physics structured?
AQA A-level Physics (7408) has three written papers, all sat at the end of Year 13:
- Paper 1 (2 hours, 34%): Measurements and their errors; particles; quantum phenomena; electricity; waves; mechanics; materials; nuclear physics
- Paper 2 (2 hours, 34%): Thermodynamics; fields (gravitational, electric, magnetic); nuclear physics; turn points; astrophysics (optional topic)
- Paper 3 (2 hours, 32%): Practical skills and data analysis (Section A, compulsory) plus one optional topic chosen from: astrophysics, medical physics, engineering physics, turning points in physics, or electronics
Students choose their optional topic in Year 12 or 13, and only one optional topic is taught and examined. This allows some specialisation: a student interested in medicine can study medical physics; one interested in the universe can study astrophysics.
AQA's Paper 3 Section A, which assesses practical skills across the entire specification, means that practical knowledge directly contributes to the graded mark — unlike the endorsement, which is pass/fail. This makes AQA more demanding in terms of integrating practical competence with exam performance.
How does OCR A-level Physics work?
OCR offers two distinct A-level Physics routes:
OCR Physics A (H557) has three papers:
- Paper 1: Modelling physics (2 hours 15 min, 37%): mechanics, waves, circuits, thermal physics, and fields modelling
- Paper 2: Exploring physics (2 hours 15 min, 37%): forces, electricity, circular motion, oscillations, and nuclear physics
- Paper 3: Unified physics (1 hour 30 min, 26%): synoptic paper drawing on the whole specification
OCR Advancing Physics B (H558) is a context-driven specification that teaches physics through applications and real-world scenarios. It was developed by the Institute of Physics and is particularly popular in schools whose teachers value the connections between physics principles and technological applications. Its three papers have a similar structure but use context-based questions where physics is embedded in a scenario.
| Feature | AQA (7408) | OCR Physics A (H557) | OCR Advancing Physics B (H558) |
|---|---|---|---|
| Total papers | 3 | 3 | 3 |
| Optional topic | Yes — one of five | No | No |
| Practical skills paper | Yes (Paper 3, Section A graded) | Yes (synoptic paper includes skills) | Yes (synoptic element) |
| Practical endorsement | Yes (pass/fail) | Yes (pass/fail) | Yes (pass/fail) |
| Teaching approach | Content-led, clear topic structure | Content-led, field-model approach | Context-first, applications-driven |
| Market share | Largest in England | Second | Smaller but specialist following |
What is the practical endorsement?
All three specifications require students to complete a Practical Endorsement — a record of required practical activities completed throughout the course. Teachers assess and sign off each practical, and the endorsement is graded pass/fail. It does not contribute to the A-level grade number but appears on the results certificate and is expected by most physics, engineering, and materials science degree courses at university.
AQA additionally assesses practical skills directly in Paper 3 (Section A), which means practical knowledge can gain and lose exam marks, not just endorsement status. This is an important distinction: AQA students who struggle with practical interpretation may find their grade affected, not just their endorsement outcome.
Which optional topics does AQA offer?
AQA's optional topic system is distinctive. The five choices are:
- Astrophysics — stars, cosmology, the Big Bang, and telescope design
- Medical physics — X-rays, ultrasound, MRI, PET scanning, and radiotherapy
- Engineering physics — rotational dynamics, thermodynamics, and engineering applications
- Turning points in physics — the discovery of the electron, Einstein's photoelectric effect, and wave-particle duality
- Electronics — operational amplifiers, signal processing, and digital circuits
Most schools offer astrophysics and medical physics, as these are popular with students and align with common degree aspirations. Engineering physics and electronics are sometimes offered as well. Turning points in physics is less common but valued by students interested in the history and philosophy of science.
Frequently asked questions
Is OCR Physics A harder than AQA Physics?
Ofqual's comparable outcomes policy ensures that a grade B in OCR Physics A represents the same standard as a grade B in AQA Physics. The papers feel different — OCR Physics A uses a fields-based organising model that some students find more conceptually coherent — but neither is systematically harder to achieve a given grade in. A student's performance depends far more on how well the teaching approach matches their learning style than on which board is theoretically more demanding.
What university courses require A-level Physics?
Physics, astrophysics, engineering (most branches), materials science, geophysics, and many joint degrees require A-level Physics. Many computer science programmes accept Physics alongside Maths. Medicine and dentistry do not typically require Physics but it is a useful supporting subject. Whichever board you study with, the A-level Physics qualification is equally recognised.
Can a student study Advancing Physics B without strong mathematical skills?
A-level Physics requires A-level Maths skills regardless of board. The content mandated by Ofqual — mechanics, electromagnetism, waves, fields — is mathematically demanding across all specifications. Advancing Physics B embeds this mathematics in context, which can make it feel less abstract, but it does not reduce the mathematical demands. Students who struggle with calculus, vectors, or algebraic manipulation will find all A-level Physics specifications challenging.
How many past papers are available for OCR Physics A vs AQA Physics?
AQA, as the largest board, has more historic past papers available and a larger ecosystem of third-party revision resources. OCR Physics A has a solid bank of past papers from the current specification cycle (first assessed 2017). OCR Advancing Physics B has fewer third-party resources. Students relying heavily on past paper practice tend to find AQA slightly better-resourced in this respect.
