About GCSE Combined Science
GCSE Combined Science (Trilogy) covers all three sciences — Biology, Chemistry, and Physics — in a single qualification worth two GCSEs. You study the core content from each discipline but in slightly less depth than the separate science GCSEs.
Combined Science is the most popular science GCSE in England and is accepted by the vast majority of employers and further education providers. It gives you a solid grounding across all three sciences and keeps your options open for A-Level study in any of them.
The main challenge is the breadth of content. You need to cover topics from three different subjects, which means effective time management and a structured revision plan are essential. Students who revise only their favourite science and neglect the others often get caught out.

Study Tips for Combined Science
- ✓ Create a revision timetable that allocates equal time to Biology, Chemistry, and Physics. It is tempting to focus on the science you enjoy most, but your grade is based on all three, so balance is key.
- ✓ Use topic checklists from your exam board specification to track what you have revised. Tick off each topic as you cover it so nothing slips through the cracks across three subjects.
- ✓ Prioritise understanding the required practicals for all three sciences. Practical-based questions make up around 15% of the marks and are often the most straightforward to prepare for.
- ✓ Make a formula sheet for Physics equations and a glossary of key terms for Biology and Chemistry. Review these for ten minutes each day to build long-term recall.
Exam Tips for GCSE Combined Science
- ✓ You will sit six papers in total — two for each science. Check which topics are on which paper so you can focus your last-minute revision appropriately before each exam.
- ✓ For calculation questions in Chemistry and Physics, always show your working and include units. Even a wrong final answer can earn method marks if your approach is correct.
- ✓ Manage your time carefully across each paper. If a question is worth 1 mark, spend about a minute on it. If it is worth 6 marks, allow yourself 8-10 minutes to plan and write a full response.
