IGCSE Science

IGCSE Double Science is worth two IGCSEs – so it’s worth doing well! Since there’s enough content to cover two IGCSEs there’s going to be plenty to learn – so make sure you get a good revision guide. (Be warned, some publishers split their revision guides into physics, chemistry and maths).


Each exam board produces a syllabus listing exactly what you need to know to pass the exams. Some students find this useful to use as checklist of what you have revised. Make sure you check with your teacher which exam board and syllabus you are following.

Revision Guides

Revision guides are printed books which summarise everything you need to know to do well in the exam, and are an important part of many people’s revision. Search our database of revision guides to find the right one for you.

Past Papers

Attempting sample and past papers is a good way to check how your revision is going, and will allow you to become more comfortable answering exam-style questions. Links to several past papers are below, some of which can be viewed for free online. They are arranged by exam board, if you don’t know which exam board your school is using then you should ask your teacher.

Online Resources

As well as buying a revision guide, you can add variety to your revision using free online resources. Bear in mind that the content of some of these websites might not be as reliable or up-to-date as printed books, check that the content matches your syllabus and if in doubt ask your teacher.
