Why choose Computer Science?

Have you ever wondered how the Web works or how to develop a computer game?

Have you ever wondered how the Web works? Or how anybody can start to develop something as complex as a new computer game? Computer Science is an exciting and challenging subject in which you will develop valuable skills in problem solving as well as learning how computers work. Many of our students go on to higher education courses in computer science but you will gain skills and knowledge which will prove useful in a wide range of other courses and careers, particularly in maths, science and engineering. The new A level course is even more strongly focussed on problem solving and programming. You will learn how to analyse problems, design algorithms and write programs. Many students have no previous experience of programming and we assume none. We provide excellent support in the form of online resources and one-to-one help. However, we also provide adequate challenge for the increasing number of students who have taken a GCSE in Computing or Computer Science.

There is an active student-run Computer Science Society which organises a programme of guest speakers giving an insight into Computer Science in Higher Education and industry. Every year students enter the British Informatics Olympiad; in previous years some have reached the national and international finals. We also support the many students who compete in the University of Southampton’s National Cipher Challenge.

“I had previous programming experience, but because the course has focussed on some of the more theoretical aspects of the subject I’ve had great fun exploring topics that I would have never come across in my own time.”
