One of the most common questions students and parents ask is: "Does it matter which exam board I'm on?" The short answer is yes — and knowing your exam board is the first step to effective revision.

In this post I'll break down the key differences between AQA, Edexcel, and OCR GCSE Science, so you can make sure you're revising the right content.

How to Find Out Which Exam Board You're On

The easiest way is to ask your science teacher. You can also check any past papers or mock exams you've been given — the exam board logo will be on the front cover. Alternatively, check your school's website or your student portal.

AQA GCSE Science

AQA is the most popular GCSE Science exam board in England, used by the majority of state schools. It offers:

• Combined Science: Trilogy — two GCSEs covering Biology, Chemistry, and Physics
• Triple Science — three separate GCSEs (Biology, Chemistry, Physics)

AQA exams are known for being straightforward in structure, with a mix of multiple choice, short answer, and extended writing questions. Required practicals are assessed through written exam questions rather than a separate practical assessment.

Edexcel GCSE Science

Edexcel (Pearson) is the second most widely used exam board for GCSE Science. It also offers Combined Science and separate sciences. Key differences from AQA include:

• Slightly different topic order and content emphasis
• Core Practicals assessed through written exam questions
• Questions can be more application-focused — applying knowledge to unfamiliar contexts

If you're on Edexcel, make sure your revision resources are specifically aligned to the Edexcel specification — not all resources are!

OCR GCSE Science

OCR offers two different GCSE Science specifications:

• OCR Gateway Science — the more commonly used option in schools
• OCR 21st Century Science — a context-led approach, less common

OCR Gateway is structured around topics (B1–B6, C1–C6, P1–P6) and is known for its clear topic structure, which makes it well-suited to retrieval practice revision.

Which Exam Board is Hardest?

Honestly? None of them. The difficulty is broadly equivalent — grade boundaries are adjusted each year to account for any differences in paper difficulty. What matters most is that you revise the right content for your exam board.

Key Takeaway

Always check your exam board before buying revision resources. Using AQA resources when you're sitting Edexcel won't cover everything you need — and could leave gaps in your knowledge.

All resources in my store are clearly labelled by exam board, so you can shop with confidence. If you're not sure which resources are right for you, get in touch — I'm happy to help.
