What is GCSE Triple Science?

If you’ve heard people talking about GCSE Triple Science at school, you might be wondering exactly what it involves, and how it differs from Combined (Double) Science.

This guide tells you exactly what you need to know to make an informed decision about your GCSE options.

Key Takeaways

• Triple Science gives you three separate GCSEs in Biology, Chemistry and Physics, each graded 9–1

• It is different from Double Science, which gives you two GCSEs covering the same subjects in less depth

• Most schools don’t require Triple Science for A Level science subjects, but it does make the jump easier

• Since many schools have entry requirements for Triple Science, ask your science teacher what these are early on if you’re keen to do it

What is GCSE Triple Science?

Triple Science, also known as Separate Science or the Triple Award, is the option to study Biology, Chemistry and Physics as three separate GCSEs. Each subject has its own specification, papers and grade.

What you'll study in each subject

GCSE Biology topics include cells, genetics and health.

GCSE Chemistry topics include atomic structure, the periodic table and properties of matter.

GCSE Physics topics include energy, forces and electricity.

See our breakdowns of the hardest topics in GCSE Biology, Chemistry and Physics for an idea of what to expect.

Triple Science vs Double Science: the key differences

Both Triple Science and Double Science cover Biology, Chemistry and Physics. However, the size of the course differs between the two options. 

Compared to Triple Science students, Double Science students learn two-thirds of the course content across all three subjects, with some of the more challenging content removed. As a result of this, Double Science students are only awarded two GCSEs at the end of the course, compared to three for Triple Science students.

See our article on Triple vs Double Science GCSE for more information.

How many GCSEs does Triple Science count for?

Triple Science gives you three GCSEs in total: one in Biology, one in Chemistry and one in Physics.

What grades are available?

Each Triple Science subject is graded separately using the 9–1 grading scale, with 9 being the highest grade.

Is Triple Science right for you?

If you’re good at science, aiming for multiple A Levels in sciences and willing to take on a heavier workload, you’ll suit Triple Science.

If you’re concerned about the heavier workload and difficulty level, Double Science is likely the better option. It still gives you two grades, can still lead to A Level sciences at most schools, and doesn’t involve as much of a time commitment.

How to choose Triple Science at school

• Check if it’s available. Some schools don’t offer Triple Science and instead run Double Science for everyone

• Talk to your science teacher before option forms go out. Most schools have entry requirements for Triple Science, so ask your teacher what these are

• Work hard to get the required grades. Your end-of-year assessment in Year 9 often decides if you’re eligible, but if you missed the grade, ask whether you can be reassessed at the start of Year 10. Schools are sometimes flexible on this.

How to prepare for Triple Science exams

Here are some tried-and-tested strategies to help you prepare for Triple Science exams:

• Look at your exam board specification. Each exam board has different topics and assessment structures, so make sure you’re revising the right areas. If you aren’t sure which exam boards you’re using, ask your science teacher

• Use a variety of revision methods, such as flashcards and diagrams. Our guide on how to revise for Science GCSE gives you the best strategies

• Complete past papers under timed conditions. Check how you did against the mark scheme

Frequently Asked Questions

Is Triple Science harder than Double Science?

Yes, as it involves more challenging content and longer papers. That’s why Triple Science awards you three GCSEs, whereas Double Science gives you two.

How many GCSEs is Triple Science worth?

Three in total: one in Biology, one in Chemistry and one in Physics.

Do I need Triple Science for A Level Biology, Chemistry, or Physics?

No, but it will make the jump easier. However, most schools accept Double Science students providing that your grades are strong enough.

Do I need Triple Science for Medicine?

No. Medical schools don't formally require it, and admissions tutors know that not every school offers it. What matters more is strong A Level grades in subjects like Biology, Chemistry, Physics and Maths.

Can I switch from Double Science to Triple Science in Year 10 or 11?

Technically yes, but it’s more realistic to switch in Year 10 than in Year 11. It also depends on your school’s policy. Speak to your head of science as early as possible to discuss your options.
