What this is
The Revision Hub is a free, growing collection of A-Level and AAQ Computing as well as additional revision resources: structured notes, interactive flashcard apps, and exam guides. Everything is free to use, with no account, no sign-up, no adverts, and no paywall. I built it as a student, for students, and that is exactly who it is still for.
Why I built it
When I was revising, I kept running into the same problem for the AAQ computing course: there was none due to the course being new, and the resources that were actually accurate sat behind a subscription. I wanted notes that tracked the specification line by line, used the exact wording that earns marks, and let me test myself quickly instead of just re-reading. Nothing did all three, so I started writing my own.
Ever since I did this, I realised that this way of learning is effective and I should do this for all of my subjects, and it made the hub grow out of those notes. I kept the standard high because I was using them for my own exams, and I made them free because revision help should not depend on whether you can pay for it. If it saves you the hours I lost hunting for material I could trust, it has done its job.
What it covers
The hub spans seven subjects and their full specifications:
- OCR Cambridge Advanced National in Computing (AAQ) F160, F161, and F162
- OCR A-Level Computer Science (H446)
- AQA A-Level Biology (7402)
- AQA A-Level Physics (7408)
- AQA A-Level Psychology (7182)
- AQA A-Level Sociology (7192)
- Edexcel A-Level Business (9BS0)
Most subjects have both full revision notes and a matching flashcard deck for every paper or theme. You can browse the whole library from the Revision Hub.
What makes the notes different
I write everything to do one thing: get you marks in the real exam. In practice that means:
- Spec-tracked, not paraphrased. The notes are curated to follow the official specification point by point, so nothing examinable is missing and nothing off-spec pads it out.
- Mark-scheme wording. Key terms and definitions use the phrasing that examiners actually credit, rather than a loose summary that reads fine but drops the mark.
- Built for active recall. The flashcards are made for fast, repeated self-testing, which beats passive re-reading. Notes and flashcards are cross-linked so you can revise a topic and then immediately quiz yourself on it.
- Curated, not generated. Every set is checked against the spec and the exam-board materials, and corrected when something is off.
How to use the hub
However you revise is fine, but if you want a routine that works, this is the one I would suggest:
- Learn it with the notes. Read through a topic in the revision notes first to build understanding and see the wording the mark scheme wants.
- Test it with the flashcards. Switch to that topic's deck and quiz yourself. Mark honestly what you got right and wrong. The cards you miss are the ones worth repeating.
- Repeat the gaps. Re-shuffle and run the deck again, focusing on the topics you keep slipping on, until recall is automatic.
- Use it anywhere. Everything runs in the browser with no login, so it works on a phone between lessons just as well as on a laptop.
What is coming next
The hub is added to regularly. New flashcard decks, expanded notes, and additional subjects go up as I write and check them, and existing pages get updated whenever a specification changes or a clearer explanation is worth adding. Subjects that currently only cover one paper will be rounded out over time. If there is a subject or topic you would find useful, tell me and it will go on the list.
Frequently asked questions
Is it really free?
Yes. Every page is free, with no account, no sign-up, no adverts, and no paywall. There is no premium tier and nothing is held back.
Can I trust the content?
The notes are written to track the official specifications and use mark-scheme wording, and they are checked against exam-board materials. They are still made by one person, so treat them as a strong revision aid alongside your own teacher's guidance and the official spec, not as a replacement for them. If you spot a mistake, please tell me.
Who makes it?
The site is made and maintained personally by me, Jack. It is independent and has no affiliation with any school, exam board, or commercial organisation. You can find more of my work at jackghx.com.
Why does it talk about Computer Science and AAQ Computing so much?
Those were the first subjects I built, because they are my own, so the site name and a lot of its descriptions grew out of them. The hub has since expanded well beyond computing and now covers seven subjects, all written and maintained to the same standard. If you came here for Biology, Physics, Psychology, Sociology, or Business, you are in the right place too.
How often is it updated?
Regularly. New decks, notes, and subjects are added as they are written, and existing pages are revised when specifications change or content can be improved.
