Physics & Maths Tutor is a free resource site, created in 2013 by Oxford physics graduate Görkem Çavlı and funded by advertising. You do not need an account. For GCSE it covers Biology, Chemistry, Physics, Maths, English, Economics, Geography and Computer Science, organised by board and then by topic, with past paper questions, mark schemes, model answers, revision notes, flashcards and video solutions, nearly all as PDFs.

Atom Home is a platform rather than an archive. You set your subjects, exam boards and exam dates, and it builds a revision plan around them, serves practice targeted at the topics you are losing marks on, and marks full-length papers against genuine exam-board mark schemes.

This is where the two part company. PMT gives you the paper and the mark scheme. What you do next — which paper, when, how strictly to mark yourself, whether your answer really earned that third mark — is entirely yours to judge.

Marking your own work is the hardest part of revising alone, and it is where most students flatter themselves. Atom Home marks the paper for you against the real mark scheme, shows where marks were gained and lost, and turns the result into a predicted grade against actual grade boundaries.

PMT solves the material problem completely and for free. There is no good reason to pay for past papers when PMT has them organised by topic with mark schemes attached.

What it does not solve is the method problem: what to revise, in what order, how long before the exam, and whether what you are doing is working. That is the part Atom Home is built for, and it is why some students sensibly use both — PMT for extra material, Atom Home for the plan and the marking.

Physics & Maths Tutor is free. Not a free tier, not a trial — the whole resource site is free to use with no account, paid for by advertising on the page. Nothing in this comparison changes that, and no paid product makes a free archive of past papers less valuable.

Atom Home plans start at £39.99 a month for English, maths and science. Exam Prep is £59.99 a month, and Exam Prep Plus, which includes unlimited mock tests with instant marking, is £69.99 a month. Annual plans save 20%, bringing Exam Prep Plus to £55.99 a month, billed at £671.90 a year.

PMT gives you past paper questions by topic, mark schemes, model answers, revision notes, flashcards and video solutions, free and without signing up. Alongside it, PMT Education runs revision courses and a tutoring platform where listed tutors charge from around £25 to £40 an hour.

Atom Home includes unlimited practice questions, AI marking, an AI tutor and a performance dashboard with predicted grades, topic strengths and gaps, and progress over time. Full-length mock tests are the dividing line between plans: included on Exam Prep Plus, not on English, maths and science or Exam Prep.

PMT does not adapt. It is the same site for every visitor, which is part of why it works: no account, no friction, everything two clicks from the homepage. You decide what to open.

Atom Home builds a picture of where you are across every topic in your specification and serves practice accordingly. The plan is built backwards from your exam dates, and what you see next is driven by where your papers show you are dropping marks.

On PMT you have the mark scheme, the model answer and, for some topics, a video solution. For a confident student that is often enough. For a student who does not understand why their answer was wrong, a mark scheme rarely explains it.

Atom Home includes an AI tutor on every plan, with annotations, flashcards and worked explanations, so the next step is explained rather than left for you to infer.

PMT's past papers are the real thing — actual past papers from the boards, with official mark schemes. The limit is that there are only so many, and once you have worked through them you have worked through them.

Atom Home's are full-length predicted papers built on real past-paper formats for your board, marked automatically and reviewed by subject specialists and former examiners. On Exam Prep Plus they are unlimited, so you can sit a fresh paper as often as you like without repeating questions you have already seen.

PMT does not track anything. There is no account requirement and no progress record, so what you have covered and how you did lives in your head or your notes.

Atom Home reports a predicted grade for each subject mapped to real grade boundaries, with topic-level strengths and gaps underneath and progress plotted over time.

With PMT, the measure is whatever you decide it is. That suits organised students and badly fails disorganised ones, because it is genuinely hard to tell the difference between revising and feeling like you are revising.

Atom Home measures marks against a real mark scheme and reports them as a grade. If the predicted grade moves, the revision is working. If it does not, you know where to look.

Nothing, with PMT — there is no account, so there is nothing for a parent to look at. For a parent wondering whether revision is actually happening, a folder of downloaded PDFs is not an answer.

Atom Home's performance dashboard gives a predicted grade against real grade boundaries and a topic-by-topic breakdown, which answers that question in a few seconds.

It is free, it is comprehensive, and it needs no account. For past papers organised by topic with mark schemes attached, PMT is the best thing on the UK internet and no subscription changes that. If money is the constraint, use it, and use it hard.

It also covers subjects Atom Home has not built yet, Economics and Computer Science among them.

If you are organised, know what you need to work on and will mark yourself honestly, PMT may be all you need. Plenty of students get their grades that way.

Atom Home is for the part PMT leaves to you: deciding what to revise and when, getting your answers marked against the real mark scheme, and knowing what grade you are actually on. One subscription gives you a plan built around your subjects, boards and exam dates, full-length predicted papers with examiner-style feedback, and a predicted grade that updates as you improve, across AQA, Edexcel, OCR and iGCSE. Using both is a perfectly sensible answer.
