What is OCR?
5 min read · updated 2026-09-02
OCR, short for Oxford, Cambridge and RSA Examinations, is the third of the big three English boards, with a lineage that runs back to the University of Oxford and University of Cambridge exam traditions and a reputation for specifications that reward deep understanding over drill.
Where OCR comes from
OCR was formed in 1998 by merging the exam operations of the University of Cambridge Local Examinations Syndicate with the RSA (Royal Society of Arts) examinations arm and the Oxford and Cambridge board's work. It sits within Cambridge University Press & Assessment today, which is why the Cambridge name is still attached to it. Like AQA and Pearson Edexcel, it is regulated by Ofqual and its grades carry identical weight.
What OCR is known for
Two things stand out. First, its sciences: OCR A is one of the most widely taken A-Level physics, chemistry and biology routes in England, with a context-led sibling (OCR B) that some schools prefer. Second, maths: OCR offers both its own A-Level maths and the MEI specification, an alternative route developed with Mathematics in Education and Industry that many schools choose for its integrated problem-solving emphasis.
In GCSE years, OCR specs are common in the sciences and humanities, and its question papers tend to lean on applying ideas to unfamiliar contexts, which is why OCR science students in particular benefit from past-paper technique rather than note-learning alone.
Preparing for OCR papers
OCR publishes past papers, mark schemes and examiner commentary openly. The preparation pattern that works: learn the topic, then immediately meet it as an exam question under timing, because OCR's unfamiliar-context framing is a skill that improves with exposure. Mark schemes reward structured reasoning chains, so writing full sentences of explanation, not one-word answers, is trained behaviour.
FAQs
Is OCR A-Level maths harder than Edexcel?＋
They are calibrated to the same standard. The MEI route has a distinctive style with more open problem-solving, and some students suit it better. What matters is practising the exact specification your school teaches; switching styles mid-course is the only real risk.
Do universities prefer any particular board?＋
No. Universities see grades, not boards. The choice of board is made by schools for teaching reasons, and admissions teams treat AQA, Edexcel and OCR identically.
