About Edexcel IGCSE Human Biology past papers
This page holds 20 question papers and 18 mark schemes for IGCSE Human Biology, covering 10 exam sittings from 2020 to 2024. Every paper is free to open, with no account and no download limit, and each one sits beside its mark scheme so you can mark your own work the way an examiner would. The most recent sitting here is May 2024.
The units covered are P1C, P2C, P1 and P2. Papers appear under more than one specification code — 4HB1 and 4CH1 — because the qualification has been revised during this period. Older papers remain useful: most of the subject content carries over, and the extra practice is worth more than a tidy archive. Each paper is labelled with its own code so you can see which generation it belongs to.
Papers here come from the January, May, October and November series — about 2.0 sittings a year across the 5 years covered, which is why there is usually a recent paper available whichever session you are entered for. 2 of the question papers here do not yet have their mark scheme beside them; the rest are complete pairs. If you need one of the missing schemes, tell us and it usually goes up within a few days.
Revising Human Biology
Human Biology covers much of the same ground as Biology, with the focus narrowed to human systems — so the revision technique is the same, and the context of the questions is not.
The systems — circulatory, respiratory, digestive, nervous — come up in some form every sitting. Being able to label a diagram and explain how a structure suits its function covers a large share of the available marks.
Health and disease questions often present unfamiliar clinical data. Read the axes and the units before the question, then work out which part of the course it belongs to.
Questions tend to be set around health, disease and the body's responses, often with real clinical data to interpret. Practising on Biology papers as well as these is genuinely useful: the question styles overlap heavily, and it gives you a much larger bank of data-response questions to work with.
As in Biology, the wording in the mark scheme is strict. Learn the precise terms for structures and processes rather than paraphrasing them.
