Three GCSEs in Biology, Chemistry and Physics


Triple Science takes place in the allocated Combined Science timetable plus one option choice. Grades awarded 9 – 1 under the new grading system.

You will study separate GCSEs in Biology, Chemistry and Physics and therefore receive a GCSE for each of the three sciences.

In Biology, you will learn about a range of topics including the transport of substances in plants and animals and using microorganisms to produce food and fuels.

In Chemistry, you will learn about topics including the development of the periodic table, what makes acids and alkalis acidic and alkaline and how to calculate the energy in various chemical reactions.

In Physics, you will learn about topics including how planets, moons and satellites remain in orbit and the effect prisms and lenses have on light.


This Triple Science course is worth three GCSEs. You will sit six examinations at the end of Year 11. Each examination contributes 50% of the final GCSE grades for each of the three separate science subjects. There will be:

  • two Biology papers leading to the Biology GCSE
  • two Chemistry papers leading to the Chemistry GCSE
  • two Physics papers leading to the Physics GCSE

You will complete practical assignments throughout the course and your understanding and application of these practicals will be assessed within the final GCSE examinations.


If you are opting for the separate sciences (Triple Science) you are likely to want to study two or more sciences at A level (Biology, Chemistry and/or Physics).

However, this does not preclude anyone with a keen interest and ability for the subject from choosing this pathway even if you are intending to study only one science at A level. This is the route that you should take if you have aspirations of continuing your study in university for veterinary science, medicine, pure sciences, dentistry, engineering or other science-related disciplines.
