The short version
IGCSE Science Revision is an independent revision resource for Pearson Edexcel International GCSE (9–1) Biology, Chemistry and Physics. We make free, concise revision videos on our YouTube channel and free digital workbooks, all written around the exam specifications and mark schemes so you can revise efficiently and walk into the exam knowing exactly what the examiner wants.
What we do
The site brings together short topic videos, quick self-check questions and printable or digital workbooks covering the full Edexcel International GCSE science courses: Biology (4BI1), Chemistry (4CH1) and Physics (4PH1). Every video is deliberately kept tight — one idea, explained clearly, in the language the mark scheme rewards — so revision fits into short, focused sessions rather than hours of scrolling.
You can work topic by topic from the Biology, Chemistry and Physics pages, mark videos as watched to track your progress, and test yourself with the quick-check questions built into each topic. Reading options (text size, an easy-reading font, dark mode and more) are there to make the material comfortable to work through on any device.
Who runs it
IGCSE Science Revision is created and run by Christopher Scargill. Everything on the site — the videos, the diagrams and the workbooks — is made in-house, which keeps the style consistent and the content closely aligned to what students actually need for the Edexcel International GCSE exams.
Qualifications and experience
The resources here are written by Christopher Scargill, a qualified science teacher with classroom experience across both mainstream and SEND (special educational needs and disabilities) settings. He holds a degree in Biomedical Science and is a qualified paramedic with experience working in the health sector.
That combination — teaching, a science background and frontline healthcare — shapes the material here: scientifically accurate, focused on exactly what the exam rewards, and explained in clear, accessible language for every learner.
Our approach
We believe good revision material should be accurate, clear and to the point. Each resource is built to match the specification and to use precise, mark-scheme wording, because in science exams the exact terms matter. We focus on the mistakes students most commonly lose marks on, and on the definitions, equations and required practicals that come up again and again.
Free videos on YouTube
Our full library of revision videos is free to watch on YouTube. If you find them useful, subscribing helps more students discover the channel: youtube.com/@IGCSEscirev.
Workbooks
Alongside the free videos, we offer free digital workbooks with notes, quick checks and exam-style practice for each subject. You can see what is available on the workbooks page. The workbooks are free and download directly from this website.
