OCR Physics A and Edexcel A-level Physics both comply with Ofqual's mandatory content for A-level Physics, meaning the fundamental topics — mechanics, electricity, waves, quantum physics, thermal physics, and fields — are the same. The differences lie in how content is packaged across papers, how mathematical rigour is distributed, and the number and style of required practicals.
What content is common across all A-level Physics boards?
Ofqual mandates that all A-level Physics specifications cover:
- Measurements and their errors
- Particles and radiation (quantum physics, nuclear physics)
- Waves (including superposition, diffraction, refraction)
- Mechanics and materials (Newton's laws, momentum, elasticity)
- Electricity (circuit theory, semiconductors, resistivity)
- Magnetic and electric fields
- Thermal physics
- Nuclear physics and radioactive decay
- Astrophysics and cosmology (in most specifications)
OCR, Edexcel, AQA, and WJEC all teach this content. The variation is in emphasis, sequencing, and how questions are phrased across the three papers each board uses.
What does OCR Physics A (H557) offer?
OCR A-level Physics A (specification code H557) organises its content in a distinctive modelling physics framework. The philosophy is that physics is fundamentally about building and testing models of the physical world. Content is arranged as:
- Module 1: Development of Practical Skills in Physics
- Module 2: Foundations of Physics
- Module 3: Forces and Motion
- Module 4: Electrons, Waves and Photons
- Module 5: Newtonian World and Astrophysics
- Module 6: Particles and Medical Physics
Three papers are assessed at the end of Year 13: Paper 1 (Modelling Physics), Paper 2 (Exploring Physics), and Paper 3 (Unified Physics). Paper 3 is synoptic across the whole specification. OCR specifies 12 Practical Activity Groups (PAGs) for Physics, and awards a Practical Endorsement.
What does Edexcel A-level Physics (9PH0) offer?
Edexcel A-level Physics (specification code 9PH0) takes a more topic-based structure:
- Topics 1–4: Core physics year 1 (mechanics, materials, waves, electricity)
- Topics 5–8: Further core physics year 1/2 (thermodynamics, nuclear/particle physics, cosmology)
- Topics 9–12: Optional topic area (one from: Astrophysics, Electrical/Electronic Engineering, Mechanics, Medical Physics, Nuclear/Particle Physics)
Three papers are sat at the end of Year 13: Paper 1 (Advanced Physics I), Paper 2 (Advanced Physics II), and Paper 3 (General and Practical Principles in Physics). Paper 3 is a synoptic paper covering the entire specification with a strong practical and data analysis emphasis. Edexcel specifies 16 Core Practicals and awards a Practical Endorsement.

| Qualification level | Full A-level | Full A-level |
How does OCR's modelling approach differ from Edexcel's topic approach?
OCR Physics A frames everything around building models of physical systems — a student learning about resistors in a circuit learns both how to calculate resistance and how that calculation is a model, with its assumptions and limitations. This integrative thinking is tested in Paper 3 (Unified Physics), which asks students to reason across multiple physics areas in a single problem.
Edexcel Physics is more conventionally structured by topic, which some students find easier to navigate during revision. Edexcel's Paper 3 (General and Practical Principles) includes a significant practical investigation element, with questions on experimental design, statistical analysis of data, and evaluation of results. Students who enjoy data work tend to find Edexcel Paper 3 engaging; those who prefer mathematical derivation and modelling often take to OCR Paper 3.
How important is the optional topic for Edexcel students?
Edexcel is distinctive in offering six optional topic areas, one of which is assessed in part of Paper 3. Students who have a clear interest in astrophysics, medical physics, or engineering benefit from choosing an option that aligns with that interest — both for motivation and for potential relevance to their university course. The choice is typically made by the school based on teacher expertise, so it is worth asking which option your school teaches before choosing Edexcel.
OCR Physics A does not have a separately examined optional topic area in the same way; its optional content (Medical Physics, in Module 6) is integrated into the main assessment.
Frequently asked questions
Is OCR or Edexcel A-level Physics harder?
Neither is consistently harder. Both are regulated by Ofqual and grade boundaries are set each year to reflect paper difficulty. Students who have strong mathematical skills and enjoy model-based reasoning sometimes prefer OCR's approach; those who prefer structured topics and substantial data work often find Edexcel suits them. The difficulty of either board depends on individual teaching quality and preparation.
Do engineering or physics degree courses prefer a particular A-level Physics board?
No UK university specifies a preferred A-level Physics board for engineering or physics degree admissions. They specify the subject (Physics and usually Maths, and often a third science or Further Maths) and the grade threshold. Both OCR and Edexcel are fully recognised.
Should I choose a school partly based on which Physics board they teach?
It is rarely worth choosing a school primarily on the basis of Physics board. School-to-school differences in teaching quality and support far outweigh the differences between boards. If you have narrowed your shortlist to two schools that differ on this, it is worth asking how many students achieve grade A or above, and what supplementary support is available — those factors matter more than the board name.
Can I self-study A-level Physics for a different board than my school teaches?
This is extremely difficult to do well. The boards' papers differ in their emphasis, and exam-format familiarity — built through extensive practice with past papers and mark schemes from the correct board — is a significant factor in final performance. Students who appear in the exam having revised content but practised the wrong board's questions frequently underperform on extended questions that require the correct board's style of answer.
