AQA GCSE Combined Science: Trilogy Past Papers & Mark Schemes

Combined Science is a vocabulary-density exam. With six papers worth 70 marks each, every paper rewards precise terminology. Build three flashcard decks (Biology, Chemistry, Physics) with the AQA-specified key terms; review at least 30 cards per day in the final 12 weeks. For Higher tier, the 6-mark extended-response question on each paper is worth 8.5% of that paper's marks. The mark scheme uses three levels: Level 1 demonstrates basic recall, Level 2 shows understanding, Level 3 shows developed connections. Practise writing Level 3 responses by chaining cause to effect to consequence, not by giving more facts. Required practicals are heavily examined and predictable because the practicals themselves are fixed. For each of the 16 required practicals, write a half-page summary covering: aim, independent and dependent variables, how variables are controlled, equipment list, hazards, expected pattern in results, sources of error. Maths in physics and chemistry papers often distinguishes 6–9 grades. Re-arranging equations, using standard form, and converting units (cm³ ↔ dm³ ↔ m³ in chemistry; µJ ↔ mJ ↔ J in physics) appear on every series. Drill these mechanically. Use the AQA-published examiner reports for each paper — they list, year by year, the specific mistakes most candidates made. Treat these as a checklist of pitfalls.
