KS4 Computer Science


A high-quality computer Science education equips pupils to use computational thinking and creativity to understand and change the world. Computer Science has deep links with mathematics, science, and design and technology, and provides insights into both natural and artificial systems. The core of computer science, ensures pupils are taught the principles of information and computation, how digital systems work, and how to put this knowledge to use through programming. Building on this knowledge and understanding, students are equipped to use information technology to create programs, systems and a range of content. Computing also ensures that pupils become digitally literate – able to use, and express themselves and develop their ideas through, information and communication technology – at a level suitable for the future workplace and as active participants in a digital world.

Students have 3 lessons per week

Computer Science gives students a real, in-depth understanding of how computer technology works. It offers an insight into what goes on ‘behind the scenes’, including computer programming, which many students find absorbing. The course consists of 2 strands both of which are assess through a 90-minute exam worth 50% of the total mark:

J277/01: Computer systems. This component will assess: 

  • Systems architecture
  • Memory and storage Computer networks, connections and protocols
  • Network security
  • Systems software
  • Ethical, legal, cultural and environmental impacts of digital technology.

J277/02: Computational thinking, algorithms and programming This component will assess:

  • Algorithms
  • Programming fundamentals
  • Producing robust programs
  • Boolean logic
  • Programming languages
  • Integrated Development Environments

Revision for examination


Outside the classroom

Pupils are encouraged to visit London's Science Museum new technology gallery: which tells the story of 200 years of communication technology.

Pupils should download an Integrated development environment such as Python to practise programming.            

Progression pathways and careers

The GCSE qualification opens up a new world of possibilities in regards to both job prospects and future Level 3 qualifications.  This course can lead onto traditional A levels and vocational equivalents. It will also equip you with life skills that will stand you in good stead for any future job.Computer Science supports a number of further education and career pathways and is very well respected academically and will be a strong support to students intending to study medicine, law, engineering, computing, foreign languages, physical sciences or maths-based courses at university. As computer Science pervades all aspects of study and contemporary research, this course supports a very wide range of career paths at university in addition to those listed above.
