Computing Key Stage 4

This exciting GCSE gives you an excellent opportunity to investigate how computers work and how they’re used, and to develop computer programming and problem-solving skills. You’ll also do some fascinating in-depth research and practical work. For example, some of the current investigations look at JavaScript, encryption and assembly language programming. 


Syllabus: OCR GCSE Computing (9-1)

Course Code: OCR J276


You will need at least a Level 3+ in maths to choose this subject.

Course overview

Computer Science is a practical subject where learners can apply the knowledge and skills learned in the classroom to real-world problems. It is an intensely creative subject that involves invention and excitement. The OCR Computer Science GCSE will value computational thinking, helping learners to develop the skills to solve problems and design systems that do so. These skills will be the best preparation for learners who want to go on to study Computer Science at AS or A Level and beyond. The qualification will also provide a good grounding for other subject areas that require computational thinking and analytical skills.

Course content

Component 1 - Computer Systems focuses on Computer Systems. 

Component 2 – Computational Thinking, Algorithms and Programming. Focuses on computational thinking and algorithms. Students will be tested on the elements of computational thinking and logic. They are principally assessed as to their ability to write, correct and improve algorithms.

Component 3 – Programming Project. This component is the non-exam assessment where candidates will be challenged by a range of exciting and engaging tasks to apply the knowledge and skills they have learned.


The course is divided into three sections: one controlled assessment and two examinations.

  • Component 1 - Computer Systems - 90 minutes’ examination 50%
  • Component 2 - Computational Thinking, Algorithms and Programming – 90 minutes’ exam 50%
