GCSE Computer Science

Syllabus Title: Computer Science GCSE

Exam Board: Edexcel

Note: This course is only available to students on the EBACC pathway.

The Edexcel GCSE in Computer Science is an essential course for anyone who wants to understand the enormous importance of computing in the world, today and in the future. You will gain an understanding of some of the most important concepts in the modern world, including algorithms, data handling, cybersecurity and systems architecture, as well as developing computer programming and problem-solving skills.

The aims and objectives of this qualification are to enable students to:

  • understand and apply the fundamental principles and concepts of computer science, including abstraction, decomposition, logic, algorithms, and data representation
  • analyse problems in computational terms through practical experience of solving such problems, including designing, writing and debugging programs
  • think creatively, innovatively, analytically, logically and critically
  • understand the components that make up digital systems, and how they communicate with one another and with other systems
  • understand the impacts of digital technology to the individual and to wider society
  • apply mathematical skills relevant to computer science


Principles of Computer Science

  • Decomposition, abstraction and algorithms; truth tables
  • Binary; data representation, storage and compression
  • Hardware and software; programming languages
  • Networks and network security; environmental, ethical and legal issues; cybersecurity

Application of Computational Thinking

  • Developing code; constructs, data types and structures; input/output; operators; subprograms


Written theory examination 1: Principles of Computer Science

  • 1 hour and 30 minutes
  • 75 marks (50% of the qualification)

Onscreen practical examination 2: Application of Computational Thinking

  • 2 hours
  • 75 marks (50% of the qualification)


Students can progress on to A Levels or BTEC Nationals in IT, Computing or Business Studies, all of which are available at RR6. The concepts learned are also useful in subjects such as maths, science and engineering.
