Science - Co-ordinated (Double) 

Course Overview 

Co-ordinated Science IGCSE is a qualification that encompasses Biology, Chemistry and Physics.

The three subject areas are taught by subject specialists but are examined together at the end of the course.

Co-ordinated Science is a dual award subject – it is worth two IGCSE grades. At the end of the course, students will be awarded two matching IGCSE grades from A* to G.

The content of the three subjects is outlined below:


  • Characteristics of living organisms
  • Cells
  • Biological molecules
  • Enzymes
  • Plant and animal nutrition
  • Transport
  • Gas exchange & respiration
  • Coordination & response
  • Reproduction
  • Inheritance
  • Organisms & their environment
  • Human influences on ecosystems


  • The particulate nature of matter
  • Experimental techniques
  • Atoms, elements & compounds
  • Stoichiometry
  • Electricity & chemistry
  • Energy changes in chemical reactions
  • Acids, bases and salts
  • The Periodic Table
  • Metals
  • Air & water
  • Sulphur
  • Carbonates
  • Organic chemistry


  • Motion

How You Will Be Assessed 

At the end of the course, you will take three exams.

  • Paper 2 is a 45 minute multiple choice paper covering all aspects of the course.
  • Paper 4 is a 2 hour written exam consisting of short-answer and structured questions. As in paper 2, this paper covers all aspects of the course.
  • Paper 5 is a practical test. It is two hours long and will be taken under examination conditions in one of the school labs. It will assess your practical skills including your ability to follow instructions, take measurements and record results, analyse data and plan and evaluate experiments.

University Courses and Career Paths 

There are a huge range of jobs and careers where Science is either essential or useful, including:

  • Medicine (nurse, doctor, paramedic, pharmacologist…)
  • Beekeeping
  • Marine conservation
  • Therapist (speech, occupational…)
  • Personal trainer
  • Tree surgeon
  • Technician (veterinary, automotive, computer…)
  • The nuclear industry
  • Volcanologist
  • Engineer (electrical, aeronautical, IT, formula one…)
  • Farming

This course also enables students to study the separate sciences at A Level.
