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, cyber security 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


  • Algorithms
  • Requirements for programming
  • Binary representation, data representation, data storage and compression; encryption and databases
  • Components of computer systems; truth tables, logic statements and pseudo-code
  • Computer networks, the internet and the worldwide web
  • Emerging trends; impact on individuals, society and the environment; ethical and legal issues


Written examination 1: Principles of Computer Science

  • 1 hour and 40 minutes
  • 80 marks (40% of the qualification)

Written examination 2: Application of Computational Thinking
