What is Quanta?

Each subject has a syllabus hub explaining how it is examined, a page for every past paper showing where its marks sit, and free topic guides. None of those pages reproduce Cambridge’s questions — see the copyright note below.

1. Questions come from real past papers. Every question in the product is a genuine Cambridge question, mapped against its official mark scheme rather than rewritten.
2. Each question is broken into skill checkpoints. A multi-step maths question is several skills, and you are marked on each — so “5 out of 8” becomes “you can form the equation but not solve the quadratic”.
3. Marking follows the published scheme. Maths is marked criterion by criterion; Economics and Chemistry multiple-choice is marked instantly with each wrong answer tied to its syllabus topic; Business essays are marked per assessment objective against the grids in the mark scheme, and a teacher can override any mark.
4. Mastery accumulates per skill. Practice is then directed at the weak ones rather than at whole papers you can already do.

Teachers get a class view showing per-student, per-skill gaps, can build papers from real past-paper questions, and can assign them to a class. Automatic marking does the first pass; the teacher keeps the final say on every mark. More for schools →

Free for individual students during beta. There is no paywall on practice, no trial limit and no advertising. Schools that want a class pilot can get in touch through the schools page. The public revision guides on this site are free to read without an account at all.

Cambridge past papers, mark schemes and examiner reports are © Cambridge University Press & Assessment, and Cambridge publishes them through its own site and through schools. Quanta is not affiliated with or endorsed by Cambridge.

The public pages on this site therefore describe papers rather than reproduce them: a paper page gives its code, length, mark total and where its marks sit across the syllabus, and never the questions, diagrams, case studies or mark-scheme text. The revision guides are written from scratch, and the worked examples in them are original questions. Past-paper content itself sits behind a student login.

Quanta runs no third-party analytics scripts and shows no advertising. What it stores is what it needs to track your progress — your account, your answers and your per-skill mastery. The privacy policy sets out the detail.
