Use official papers for authentic exam practice, then fill gaps with unlimited AI Combined Science questions on CampusO₂ — ideal for drilling required practicals, equations and extended writing across all three sciences.

• Rotate across Biology, Chemistry and Physics each week
• Revisit calculation-heavy questions until method marks are secure
• Learn mark scheme vocabulary for 6-mark responses
• Covers both Trilogy and Synergy routes

Frequently asked questions

How many exam papers are in AQA GCSE Combined Science?

AQA Combined Science Trilogy has six written papers — two Biology, two Chemistry and two Physics. Foundation papers are 1 hour 15 minutes each; Higher papers are 1 hour 45 minutes. You receive two GCSE grades on your certificate (a double award), shown as two numbers such as 7-6.

What is the difference between AQA Combined Science Trilogy and Synergy?

Trilogy is the most common route: Biology, Chemistry and Physics are taught and examined separately across six papers. Synergy combines content differently with four papers (two at Foundation, two at Higher). Check with your school which specification you follow, because past papers and topic emphasis differ between the two routes.

How is Combined Science different from Separate Sciences?

Combined Science covers reduced content across all three sciences and awards two GCSE grades. Separate Sciences (Biology, Chemistry and Physics) are three full GCSEs with greater depth per subject. Past papers for Combined Science are not interchangeable with Separate Science papers — always practise the papers for your entered qualification.

Should I use Foundation or Higher tier past papers?

Use papers that match the tier your school has entered you for. Foundation tier targets grades 1-5; Higher tier targets grades 4-9. You sit the same tier across all six papers, so do not mix Foundation and Higher papers when practising.

How should I use AQA Combined Science past papers effectively?

Complete one full paper under timed conditions, mark it immediately with the official mark scheme, and log errors by topic and question type — calculations, required practicals and 6-mark extended responses. Rotate across Biology, Chemistry and Physics each week. Once you identify weak areas, drill them with targeted AI practice on CampusO₂.

Are AQA Combined Science past papers free on CampusO₂?

Yes. Browse and download official AQA question papers, mark schemes and examiner reports by year at no charge. You can also sign up to practise online with instant AI feedback on Combined Science topics.

What topics appear in AQA Combined Science past papers?

Papers draw from all three sciences: cell biology, organisation, infection, bioenergetics, homeostasis, inheritance and ecology; atomic structure, bonding, quantitative chemistry, chemical changes, energy and rates; forces, energy, electricity, waves, magnetism and the particle model. Required practicals from Biology, Chemistry and Physics can be tested in any paper.
