Our IGCSE Science Experts
IGCSE Science Grade Boundaries
Looking at previous years’ grade boundaries can help you understand roughly where your current performance sits. Although actual grade boundaries aren’t released until results day, past boundaries give a useful indication of how many marks have historically been needed for each grade and where you might want to focus your revision. For example, in 2025, on the Edexcel (Pearson) IGCSE Science paper, a score of around 156 would have achieved a grade 9, while about 127 would have been enough for a grade 7.
IGCSE Science Specifications
Understanding your exam specification means you can revise what matters. The IGCSE science exam offers a broad range of exam options, from physics through to biology and chemistry, so knowing the specifics of your exam will save you a lot of time and a lot of effort.
Frequently Asked Questions
Is IGCSE science hard?
Some students consider IGCSE science to be hard because of the breadth of topics it covers. Physics, biology and chemistry all need to be understood to score a good grade, whereas a combined science mixes general science knowledge across different disciplines.
What is the hardest science in IGCSE?
There is no ‘easy’ science in the IGCSE science qualification. All of them - physics, biology and chemistry - require dedicated revision and a good understanding of the exam specifications to get a good grade.
How to do well in IGCSE science?
The best way to achieve a good grade in IGCSE science is to have a good understanding of the exam specifications, and revise the topics that matter most. By knowing what is expected of you, you can focus your time and energy where it counts.
