What will I learn?

Computer Science is a very practical subject – students will be able to use the knowledge and skills they learn in the classroom on real-world problems. It’s also a highly creative subject that calls on learners to be inventive. To help OCR develop this engaging, modern qualification, they talked to companies like Microsoft, Google and Cisco; organisations like Computing At School (CAS) and also teachers and academics.


How will this course be assessed?


  • Study how processors work.
  • Investigate computer memory and storage.
  • Explore modern network layouts and how they function.
  • Build skills in the ever important realm of cyber security.
  • Investigate how types of software are used within computer systems.
  • Stretch wider comprehension of how computers and computing affect ethical, legal, cultural and environmental issues.


  • Study fundamental algorithms in computer science.
  • Build a firm foundation in programming techniques.
  • Produce programs through diagrams.
  • Thoroughly test programs and make them resistant to misuse.
  • Explore Boolean algebra (AND, OR, NOT).
  • Understand how we store data within computers in binary form.


  • Use new-found programming skills on an independent coding project by solving a real-world problem of their choice.
  • The project is carried out under exam-like conditions.

There are two exam papers at the end of the syllabus, one focusing on computer systems and one with a focus on computational thinking, algorithms and programming. Each paper lasts 1.5 hours and is worth 40% of the total GCSE. Students will also complete a programming project in the final year of the course that will take a total of 20 hours to complete, and is worth 20% of the final GCSE award.


What skills do I need?

  • Require a grade 5 minimum in Mathematics at KS3.
  • Have a keen interest in computers and enjoy programming.


What is next for me after this course?

Our GCSE (9-1) Computer Science is effective preparation for a range of qualifications including:

  • A-level Computer Science.
  • Cambridge Technicals – IT Level 3 or Digital Media Level 3 (these are OCR vocational qualifications that offer an alternative to A levels for students aged 16+). 


Are there any restrictions with this course?

Only access the Mathematical content if grade 5 in Maths and KS3.
