Computer Science

Why study A level Computer Science?

The study of Computing is designed not just to teach and improve your skills in using computer programming languages, but also to enable you to understand the kind of reasoning used by both humans and machines.

The study of Computing demands both logical discipline and imaginative creativity in the selection and design of algorithms and the writing, testing and debugging of programs. It relies on an understanding of the rules of language at a simple level and encourages an awareness of the management and organisation of computer systems. It will require you to investigate and understand situations beyond the school environment and the appreciation of the effects of computer applications on society and individuals. For these reasons, computing is a relevant choice whether you are studying Arts subjects or Science subjects.

What are the careers or further education that this course be suitable for?

Computers are widely used in all aspects of government, business, industry, education, leisure and the home. In this increasingly technological age, a study of Computing, and particularly how computers are used in the solution of a variety of problems, is not only valuable to the students themselves but also essential to the future wellbeing of the country.

Studying Mathematics and/or Further Mathematics clearly works well, especially for those students who intend to go on to study Computer Science at university. Other common combinations are physics, economics or business studies. However, many other combinations are equally viable depending on your chosen career.
