Computer Science

The GCSE in Computer Science is a fun and challenging qualification that will enable you 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.

The qualification consists of three units of work. Two units are externally assessed through a written exam taken at the end of Year 11. One unit of work is assessed internally through the completion of a 20 hour controlled assessment. The units of work comprise of the following:

  • Component 1 – Computer Systems – 1 ½ hour exam (50%)
  • Component 2 – Computational thinking, algorithms and programming – 1 ½ hour exam (50%)
  • Component 3 – Programming Project – to be completed over 20 hours under controlled assessment conditions

Component 1 – Computer Systems

You will study the following:

  • Systems Architecture
  • Memory
  • Storage
  • Wired and wireless networks
  • Network topologies, protocols and layers
  • System security
  • System software
  • Ethical, legal, cultural and environmental concerns

Component 2 – Computational thinking, algorithms and programming

You will study the following:

  • Algorithms
  • Programming techniques
  • Producing robust programs
  • Computational logic
  • Translators and facilities of languages
  • Data representation

Component 3 – Programming project

Students must create a program using a high level programming language to solve a problem set by the examining board.
