What are the best free GCSE revision resources?

The most underused free resource: your exam board

AQA, Edexcel, OCR, WJEC and Eduqas all publish, free, the three documents that define your exams: the specification (the exact list of everything examinable - nothing outside it can appear on your paper), past papers, and mark schemes. The specification turns "have I covered everything?" from a feeling into a checklist. The mark schemes teach you what examiners actually award marks for, which is regularly different from what students assume. Most students never open any of these; the ones who do have a structural advantage that costs nothing.

The free list, by job

Each of these is genuinely free and genuinely good at its job:

• Exam board websites - specifications, past papers, mark schemes: the skeleton of any revision plan.
• BBC Bitesize - broad, board-aware content summaries and videos across nearly every GCSE subject.
• Seneca (free tier) - structured courses that quiz you as you read, with spaced repetition built in.
• Physics & Maths Tutor (PMT) - a huge library of past papers, topic questions and notes, strongest in maths and the sciences.
• Corbettmaths - maths videos, textbook exercises and the famous 5-a-day practice sheets at every level.
• Maths Genie - maths topics organised by grade, each with a video, exam questions and worked solutions.
• Anki - free, powerful spaced-repetition flashcards for quote-heavy and fact-heavy subjects (worth the learning curve).
• YouTube subject channels - board-specific walkthrough channels exist for most subjects (the science revision channels that go video-by-video through each specification are the best-known example); check the video matches your board and specification year.
• Your local library - quiet space, free wifi, and usually a shelf of revision guides you can use without buying.

Combining them into a system

A pile of resources is not a plan, so give each one a role. Use the specification as your master checklist of topics. For each topic: learn or refresh the content (Bitesize, Seneca, a YouTube walkthrough), then practise questions on it (PMT topic questions, Corbettmaths or Maths Genie for maths), then check your answers against the real mark scheme, honestly. Log the topics where marks leaked and cycle back to them sooner. That loop - content, questions, mark scheme, repeat - is the whole method, and every link in it is free.

The discipline that makes it work: spend most of your time on the questions, not the content. Rereading feels productive and mostly isn't; retrieving under mild pressure is what builds exam performance.

What paid tools add - honestly

Nothing above is a cut-down version of a paid product; it is the real material. What paid tools sell is on top: adaptivity (questions matched to your level, so you're neither bored nor drowning), feedback (marking and explanations without waiting for a teacher), and structure (the next-topic decision made for you, which is worth more than it sounds when motivation is low). Those are real conveniences that save real time - but they are conveniences. A student who works the free loop above diligently needs none of them; a student who finds the free loop hard to sustain alone is exactly who they're for.
