Thomas Keble ICT Key Stage 4

Computer Science KS4




GCSE Computer Science from OCR

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.

There is only one tier of entry.


What sort of things will I learn?

This three-unit course is designed to give you an in-depth understanding of how computer technology works and a look at what goes on ‘behind the screens’.

You don’t need to have studied this subject before, and assessment is quite simply based on a written exam, a practical investigation and programming tasks.


What skills will I get from it?

The course will help you learn about critical thinking, analysis and problem-solving. We hope you’ll find it a fun and interesting way to develop these skills, which can also be transferred to other subjects and even applied in day-to-day life.

The computer systems and programming unit will teach you the theory about a wide range of issues such as hardware and software, the representation of data in computer systems, databases, computer communications and networking, programming and more.

The practical investigation is all about engaging with computing in the real world. You’ll look at a computing topic in more depth and carry out a practical investigation into a computing issue.

The programming project will call on you to design, code and test a solution to three tasks using a suitable programming language.


How is it assessed?

 There are two 90-minute exams – Computer Systems and Computational Thinking, Algorithms and Programming, which are sat at the end of Year 11, and are worth 80% of the final grade.

There is also a NEA (non-examination assessment) which is worth 20% of the final grade.  This will be done in the autumn term of Year 11.
