IGCSE Biology Revision
Revision doesn't happen by osmosis, unfortunately. IGCSE Biology covers everything from cell structure and genetics to ecosystems and human physiology, and there's a lot of it to absorb. Our teacher-written revision notes, exam questions, flashcards, target tests, mock exams, and past papers give you everything you need to get to grips with the content, and head into your exam prepared. Got a Biology class to prepare? You can save hours of prep time with our full suite of IGCSE Biology revision resources that are ready to use for lessons, independent revision, and exam practice.

Frequently Asked Questions
Is IGCSE Biology harder than GCSE Biology?
IGCSE Biology is not necessarily harder than GCSE, but it does feel different. The content is broader and goes into greater depth in places, and the extended tier requires strong exam technique and the ability to apply knowledge to unfamiliar contexts. With the right revision resources, IGCSE Biology is very manageable.
What do you learn in IGCSE Biology?
IGCSE Biology covers the building blocks of life and how living organisms function. Core topics include cell biology, nutrition, respiration, transport in plants and animals, disease and immunity, genetics and inheritance, and ecology. You'll also study human biology in depth, from the digestive and circulatory systems to hormones and reproduction. The exact content varies slightly between CIE, Oxford AQA, and Edexcel, so check your specification for the full topic list.
