Computer Science is one of the fastest growing academic disciplines. Part science, part creative and part humanities, it is theoretical, practical and challenging.

The one year AS course will introduce you to programming with a high level language, show you in detail how computers work and develop your understanding of the impact computing has had and will have in the future and  how they influence societies and individuals.

The AS course is a stand-alone course so there is no requirement to have done the GCSE Computer Science Course, however if you have done Computer Science at GCSE see our recommended minimum below:

  • Maths: Level 7
  • Computer Science: 7
  • Experience coding in Python or another High-Level Language

AS computer science would suit students who were either:

  • considering reading Computer Science, Robotics, Artificial Intelligence or some other course where a foundation in coding and how computers work will support their application
  • considering reading engineering, sciences, medicine or any other course that is using computers and technology in a transformational way...
