Where can I download Cambridge past papers for free?

Several free archives host Cambridge question papers and mark schemes, including Physics and Maths Tutor, Papacambridge, and Save My Exams past paper pages. Your school may also have official access through the Cambridge teacher portal. Always download the mark scheme alongside the paper so you can mark your own work.

Are free revision notes as good as paid ones?

Often yes for the core content. Free notes from sites like Physics and Maths Tutor and student-shared summaries cover most of the syllabus well. Paid sites tend to add polish, structure, and large question banks, but you can revise effectively without paying if you are organised.

What is the single most important free resource?

Official past papers with their mark schemes. Nothing prepares you better than doing real questions under timed conditions and then marking yourself against the exact scheme examiners use. Everything else supports this core habit.

The Best Free Cambridge Revision Resources (2026)

Short answer: You do not need to spend money to revise well for Cambridge exams. The most valuable resource, official past papers with mark schemes, is free. Add free topic notes, YouTube walkthroughs, and the official syllabus document, and you have almost everything you need. Below is an honest rundown of the best free options in 2026, what each is good for, and where the limits are.

Start here: official past papers and mark schemes

If you only use one thing, use past papers. They are the real questions, written by the same board that sets your exam, and the mark schemes show you exactly how marks are awarded.

Where to find them: free archives such as Physics and Maths Tutor, Papacambridge, and the past-paper sections of several revision sites host years of Cambridge question papers and mark schemes. Many schools also have official access.
How to use them: do a paper under timed conditions, then mark it yourself against the scheme. The marking is where the learning happens, because you see the precise wording examiners reward.
The limit: past papers show you the answer, not why you got it wrong or how to phrase a better one. For that you need notes or a tutor.

The official syllabus document (underrated and free)

Cambridge publishes the full syllabus for every subject on its own website, free. It lists every single thing you can be tested on. Print it, and tick off each point as you master it. Students routinely revise topics that are no longer on the syllabus, or miss ones that are, simply because they never read this document. It is the definitive checklist.

Free topic notes and summaries

Good free notes save you the time of making everything from scratch.

Resource	Best for	Honest limitation
Physics and Maths Tutor	Free notes, past papers, topic questions for sciences and maths	Layout is basic, coverage varies by subject
Save My Exams (free tier)	Clean topic notes preview	Most question banks and model answers are paid
Student-shared notes (Quizlet, Google Drive folders)	Quick summaries and flashcards	Quality varies, always cross-check facts
Cambridge endorsed textbook (school copy)	Full, reliable coverage	Not always free to own, but usually free to borrow

Cross-checking matters. Free student notes can contain small errors, so if something contradicts your textbook or the mark scheme, trust the official source.

Free video walkthroughs

YouTube has strong, free channels that teach whole Cambridge topics and work through past-paper questions step by step. They are excellent when a written explanation has not clicked, because hearing a topic explained a second way often makes it land. Search for your subject code (for example "0610 osmosis" or "9709 differentiation") to find focused videos rather than general ones. The limit is that video is passive: you still need to do questions yourself afterwards.

Free tools that help you revise smarter

Flashcard apps like Anki are free and use spaced repetition, which is genuinely one of the most evidence-backed ways to remember facts.
A simple timer turns any past paper into realistic exam practice.
A revision timetable template (plenty are free) keeps you covering every subject rather than only your favourites.

Where a free AI tutor fits in, honestly

Past papers and notes are brilliant, but they cannot answer your specific question at 11pm the night before a test, or tell you whether the answer you just wrote would actually score. That gap is where an AI tutor helps.

To be honest about it: general tools like ChatGPT can explain a concept, but they do not know your exact Cambridge syllabus and will happily give you an answer that is right in general but not what the mark scheme wants. ExamPal is one option built specifically for this: it is an AI tutor that already knows the Cambridge syllabus and marks your written answers against the mark scheme, and it has a free tier. It is not a replacement for doing past papers, and we would not pretend it is. Use it alongside the free resources above, not instead of them.

A simple free revision plan

Putting it together, here is a plan that costs nothing:

Print the official syllabus and use it as your master checklist.
Read free notes or watch a video to learn each topic.
Make Anki flashcards for the facts you keep forgetting.
Do a past paper under timed conditions.
Mark it against the official mark scheme and note every point you missed.
Get an explanation for the ones you still do not understand, from notes, a video, a teacher, or an AI tutor.
Repeat, focusing more time on your weakest topics.

The bottom line

The best Cambridge revision setup in 2026 is mostly free. Official past papers and mark schemes do the heavy lifting, the syllabus document keeps you on track, and free notes and videos fill the gaps. Paid products can add polish, but they are optional. Spend your money on nothing until you have exhausted the free core, and you will still be well prepared.
