Computing GCSE

Why should you study Computing?


This carefully planned course 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.

  • It’s a great way to develop critical thinking, analysis and problem-solving skills, which can be transferred to further learning and to everyday life.
  • Students who want to go on to higher study and employment in the field of computer science will find it provides a superb stepping stone.
  • Students will develop their understanding of current and emerging technologies and how they work.
  • Students will acquire and apply creative and technical skills, knowledge and understanding of IT in a range of contexts.
  • Students will evaluate the effectiveness of computer programs/solutions and the impact of computer technology in society.
  • Students will develop computer programs to solve problems.


So… what does the new Computing course offer? – It consists of three units:

3. Unit A453: Programming Project

Assessment and duration


Students will need to:

• Understand standard programming techniques

• Be able to design a coded solution to a problem

  including the ability to:

   - Develop suitable algorithms

   - Design suitable input and output formats

   - Identify suitable variables and structures

   - Identify test procedures.

• Create a coded solution fully annotating the

  developed code to explain its function

• Test their solution:

   - To show functionality

   - To show how it matches the design criteria

   - Identifying successes and any limitations.

Controlled assessment Programming task. Design, develop and test a solution  to a problem within the OCR-set scenario.
