GCSE Double Science

Study biology, chemistry and physics through our new IGCSE Double Science online course.


If you want a good grounding in all the sciences, then our Double Science IGCSE may suit you well.  

The course is equivalent to two GCSEs, with 21 sections – seven each in biology, chemistry and physics. By studying three sciences in this way you will gain a broad perspective.

Double Science opens up a fascinating world of discovery. As Professor Brian Cox says: “One of the great joys of science is to understand something for the first time–to really understand, which is very different from, and far more satisfying than, knowing the facts.”

By studying science you’ll also develop skills of enquiry, accuracy, initiative and inventiveness – qualities that are highly valued by universities and employers. Our Double Science specification enables the learner to develop essential skills in enquiry, problem-solving and analysis in a flexible way which suits their lifestyle. Covering three sciences helps students make an informed choice about pursuing science in the future, such as at A level. It also provides a strong foundation for students wanting to go on to health-related professions like nursing or physiotherapy. Apprenticeship providers, universities and employers value candidates who can demonstrate science-based skills. 

Why study Double Science?

If you’re keen to gain a broad introduction to scientific thinking, our IGCSE Double Science online course is perfect. From studying the human circulatory system to explaining how a rainbow is made, through Double Science you’ll open up a fascinating world of discovery.

By choosing online distance learning, you’ll have the flexibility to fit study around your lifestyle, learning at your own pace as you work through a series of engaging topics.

Our Double Science IGCSE course is ideal if you:

  • Are keen to gain a broad foundation in the key ideas and applications of biology, chemistry and physics.
  • Want to learn more about how science is studied and applied.
  • Would like to discover how scientific research impacts everyday life.
  • Are interested in building your observational, analytical and problem-solving skills, to improve your employability.

Future opportunities

  • Employers value candidates who can demonstrate science-based skills – such as enquiry, accuracy, initiative and inventiveness.
  • Gaining a firm foundation in each subject will help you make an informed choice about pursuing science at A level.
