Computer Science

Apply NowSubject Leaflet

Computer Science is a subject that spans theory and practice. You will become a confident programmer using different languages to solve problems. We will apply Computational Thinking to decompose larger problems into smaller ones and use a range of techniques to solve them.

In A Level Computer Science, you will learn about many interesting theory topics such as how encryption allows the safe transfer of private data over public networks. You will learn about security issues such as hacking and how viruses are spread. Programming is a key part of the course. You will be taught programming concepts in a range of languages and complete weekly challenges.

You will choose your own engaging project idea, and develop your own program for a client or for fun, such as a 3D game using Unity.
