What’s the difference between combined science (double award) and triple science (separate sciences)?
Both routes cover Biology, Chemistry, and Physics. The difference is how much detail you study and how many GCSEs you come out with.
Below is a clear breakdown to help you choose the option that fits you best.
Combined Science (Double Award)
What it is
Combined Science teaches all three sciences, but with slightly less content than Triple Science. You still get a full, balanced understanding, just without the extra depth.
How it’s assessed
- Six exams: two for Biology, two for Chemistry, two for Physics
- Your scores are combined into two GCSE grades (e.g. 6–6, 5–4, 7–6)
What you get
✔️ 2 GCSEs
✔️ Full national curriculum coverage
✔️ A solid foundation for future study
✔️ A manageable workload for most students
Who it’s best for
Perfect if you want strong science knowledge without taking on the extra content of Triple Science.
Triple Science (Separate Sciences)
What it is
Triple Science teaches Biology, Chemistry, and Physics as separate GCSEs. There is more content and greater depth in each subject.
How it’s assessed
- Six exams in total (two per subject), just like Combined Science
- You receive three separate GCSE grades – one for each science
What you get
✔️ 3 GCSEs
✔️ Deeper scientific understanding
✔️ Excellent preparation for A-level sciences and STEM pathways
Who it’s best for
A great fit if you:
- enjoy science
- feel confident with the subject
- are considering A-level sciences or a future STEM career
Do you need Triple Science to take A-level sciences?
Good news – you don’t need Triple Science to take A-level Biology, Chemistry, or Physics.
Combined Science prepares you well, as long as you meet the grade requirements. Triple Science just gives you a bit more background knowledge going in.
Which option should you choose?
Think about:
- how confident you feel in science
- if you’re consistently getting good grades for science
- how much revision time you want to commit
- whether you enjoy studying topics in extra detail
- your future course or career plans
