Frequently Asked Questions
How many GCSEs is Combined Science worth?
GCSE Combined Science (Trilogy or Double Award) is worth two GCSEs. Students receive a double grade such as 7-7 or 5-4 reflecting their overall performance across biology, chemistry and physics.
How is GCSE Combined Science assessed?
It is assessed by six written papers — two each for biology, chemistry and physics. With AQA each paper lasts 1 hour 15 minutes and is worth 70 marks, sat at the end of the two-year course.
What is the difference between Combined Science and the separate sciences?
Combined Science covers slightly reduced content and gives two GCSEs, while Separate (Triple) Science covers each subject in more depth and awards three GCSEs, one for biology, chemistry and physics each.
How is GCSE Combined Science graded?
It uses a 17-point scale from 9-9 down to 1-1. A 4-4 is a standard pass and 5-5 a strong pass. Grades are awarded as a double grade rather than a single number.
Do students get a formula or equation sheet?
For exams in 2025, 2026 and 2027, AQA provides physics equation sheets and chemistry data, so students do not need to memorise all the usual physics equations for Combined Science.
Are there foundation and higher tiers?
Yes. Combined Science is tiered: foundation tier targets grades 5-5 down to 1-1, and higher tier targets 9-9 down to 4-4 (with a safety-net 3-3). Students sit all papers at the same tier.
