Key Stage 4

IGCSE Computer Science

All students will follow an IGCSE computer science course which will lead on to A level. Computer Science - how computers and computer systems work, and how they are designed and programmed. Pupils studying computing gain insight into computational systems of all kinds. It allows us to solve problems, design systems and understand the power and limits of human and machine intelligence. pupils who can think computationally are better able to conceptualise and understand computer-based technology, and so are better equipped to function in modern society

Computer Science syllabus aims are to develop:

  • computational thinking that is thinking about what can be computed and how, and includes consideration of the data required
  • understanding of the main principles of solving problems by using computers
  • understanding that every computer system is made up of sub-systems, which in turn consist of further sub-systems
  • understanding of the component parts of computer systems and how they interrelate, including software, data, hardware, communications and people skills necessary to apply understanding to solve computer-based problems using a high-level programming language.
