Physics & Maths Tutor (PMT) vs cambridgepapers.io — for Cambridge (CAIE) students

Facts checked July 2026; every claim links to its source. Tell us if something is out of date.

Physics & Maths Tutor is one of the best free resources in exam prep: real past papers, questions sorted by topic, and solid notes — all without a paywall. For CAIE maths and science students it is genuinely useful. The difference is what happens after you attempt a question.

What Physics & Maths Tutor (PMT) does well

• Completely free real past-paper PDFs with mark schemes
• First-class CAIE coverage in Maths, Physics, Chemistry and Biology
• A decade of trusted topic-sorted question packs

Where it falls short for CAIE past-paper practice

• Everything is static PDFs: you download the paper, write your answer, then mark yourself against the mark-scheme PDF. There is no interactive answering, no automated marking and no feedback anywhere on the site. (source)
• CAIE depth is concentrated in maths and the sciences; most of the wider Cambridge catalogue (humanities, languages, vocational subjects) is not covered. (source)

Which should you use?

Choose Physics & Maths Tutor (PMT): Choose PMT if you want printable PDF packs to work through on paper, or its UK-board content — it is free and excellent at what it does.

Also free.
