Introduction

Learners studying Computer Science develop their understanding of the main principles of problem solving using computers. They can develop computer-based solutions to problems using algorithms and a high-level programming language such as vb.net and python. Learners also develop a range of technical skills, as well as being able to effectively test and evaluate computing solutions. Studying Computer Science will help learners appreciate current and emerging computing technologies, the benefits of their use and recognise potential risks.

DO NOT confuse Computer Science with ICT.  Instead the emphasis is on computational thinking. Computational thinking is a kind of reasoning used by both humans and machines. Thinking computationally is an important life skill.

Careers and Progression

Computer scientists are in demand and their salaries reflects this. Recent graduates in professional roles earn lots on average.

Whilst we would hope you would continue to study computer science at A-Level, you could go on to a career in medicine, law, business, politics or any type of science.
