The 8 best free A-level revision websites and apps in 2026

A-level revision has a reputation for being the point where free tools run out and you have to start paying. That is mostly a myth. Between them, a handful of genuinely free websites and apps cover almost the entire job: learning the content, practising past papers, and drilling it into memory. The trick is knowing which free tool does which part, and where each one’s free tier quietly ends.

This list is free-first: every tool here has a genuinely useful free tier, and we are honest about the limits. If you are happy to mix in paid options too, our wider guide to the best A-level revision apps covers those. Details were checked in July 2026 and are linked at the end.

How far can free actually get you at A-level?

Further than most students expect. Good revision is really three jobs: learn the topic, practise exam questions, and revisit it so it sticks. There is at least one excellent free tool for each:

• Learn it: Seneca and Khan Academy teach topics for free, interactively.
• Practise it:Physics & Maths Tutor and the exam boards give you past papers and mark schemes for free.
• Remember it: free flashcard and generation tools handle spaced-repetition recall.

What you usually pay for is convenience, everything in one place, AI marking, or an ad-free experience, not the core content. Here are the eight free tools worth building your A-level revision around.

The 8 best free A-level revision websites & apps

1. Seneca — free interactive courses

Seneca is the backbone of a free A-level setup. Its smart-learning courses are mapped to your exam board, cover a wide range of subjects, and teach through quick recall questions rather than passive reading, and the core is genuinely free. For learning and revising the actual content, nothing free is more complete.

Where free ends: its most useful exam extras (more open-ended questions, mini-mocks and the Amelia AI assistant) sit on Premium tiers from around £6.99 a month, and it is stronger for science than essay subjects. Most students never need to pay. If you have hit its limits, see the best Seneca alternatives.

Best for: learning and revising A-level topics interactively, free · Free · Premium from £6.99/mo

2. Physics & Maths Tutor — free past papers and notes

For the sciences and maths especially, PMT is the free past-paper library that carries a lot of A-level students: past papers with mark schemes, topic questions, worksheets and revision notes, all organised by board. It is completely free, funded by a separate tutoring arm.

Where free ends: nowhere, really, the resources are all free. Its limit is that it is static PDFs with no teaching or feedback, so it is a library, not a tutor. We cover the ways round that in the best Physics & Maths Tutor alternatives.

3. Khan Academy — free concept mastery

When an A-level maths or science topic simply will not click, Khan Academy is the best free place to fix that: video lessons paired with practice that adapts as you go, built to take you from confused to confident on the underlying idea.

Where free ends: it is entirely free, but it follows a US curriculum rather than AQA, Edexcel or OCR, so use it to understand the concept, then return to a UK tool for board-specific practice. It is also light on essay subjects.

Best for: understanding a maths or science concept from scratch, free · Free

4. Aicademy (free tier) — generated lessons and quizzes on any topic

Aicademy earns its place here for the exact topic that is not in anyone else’s catalogue. Its free tier lets you generate a lesson, quiz and spaced-repetition flashcards for any A-level topic (or from your own notes), built for UK exam boards, with an AI tutor for the parts that do not land. It is the free tool for “explain and drill this” when a specific subtopic is costing you marks.

Where free ends: the free tier has a monthly cap on how much you can generate and a daily limit on tutor messages, and it does not have real past papers. Unlimited generation and the full tutor are £4.99 a month. Within the free allowance, though, it does something the fixed catalogues cannot.

5. freesciencelessons & subject YouTube — free video teaching

A-level sciences are well served by free YouTube. freesciencelessons covers biology, chemistry and physics in concise, spec-aligned videos, and most subjects have a trusted channel or two (from Cognito to subject-specialist teachers). It is the free way to have a topic taught to you rather than read.

Where free ends: it is all free, but it is video, so passive unless you pair it with practice, and coverage and quality vary by channel and subject. Use it to learn, then test yourself elsewhere.

Best for: having A-level science topics taught on video, free · Free

6. Quizlet (free) — ready-made flashcard sets

For recall, Quizlet’s free tier still gives you basic flashcards and access to millions of user-made A-level sets, so for many topics you can revise without building anything. It is the easiest free on-ramp to flashcards.

Where free ends: Quizlet has moved its better study modes (unlimited Learn and Test) behind Quizlet Plus, and user-made sets vary in accuracy, so check them. For free alternatives that kept more unlocked, see the best Quizlet alternatives.

7. BBC Bitesize — free quick intros

Bitesize is completely free with no login, and for a plain first explanation of a topic it is still worth a look at A-level. It is best as the gentle five-minute intro before you go deeper elsewhere.

Where free ends: it does not, but its A-level coverage is much thinner than its excellent GCSE material, so it runs out fast at this level. See the best BBC Bitesize alternatives for what to pair it with.

Best for: a quick, free first read on a topic · Free

8. Your exam board’s website — free official past papers

The most underused free resource of all: AQA, Edexcel, OCR and WJEC publish their own past papers and mark schemes free, including the most recent ones that third-party sites may not have yet. For authentic practice under real conditions, go straight to the source.

Where free ends: it does not, but the boards give you whole papers with no topic sorting or teaching, which is exactly the convenience PMT adds on top. Use the board for the newest papers, PMT for topic-sorted practice.

Best for: the most recent official past papers, straight from the board · Free

How to build a free A-level revision setup

The winning move is not one site, it is a small stack that covers the whole loop. A simple, entirely free setup:

• Learn each topic on Seneca or a video channel, and use Khan Academy or Aicademy’s free tier when something will not click.
• Practise on Physics & Maths Tutor and your exam board’s papers.
• Remember it with free flashcards on Quizlet or a generated deck, revisited over time.

That covers almost everything A-level throws at you without a subscription. For the method that ties it together, see how to revise for A-levels, and if you later want to add a paid tool, weigh it against the full A-level app list.

One note in the interest of honesty: Aicademy is our own app, included here for its free tier. We have ranked the free heavyweights, Seneca and PMT, ahead of it on their merits, and been clear about where our free allowance runs out. You can try the free tier and generate a lesson on your weakest topic in a couple of minutes.
