About this course

The Computer Science AS Level programme is a one-year course of study and should be taken in conjunction with two or three other subjects and the Welsh Baccalaureate. 

Based at our City Centre campus in Cardiff, learners may be able to take this qualification as a part-time student. 

The study of Computer Science encompasses a substantial accepted body of knowledge, and the purpose of the A-Level and AS examinations in Computer Science is to recognise this with a reputable qualification that is relevant to a student who intends to pursue a career in either the Arts or Sciences, Computing or Mathematics.

Computer Science integrates well with subjects across the curriculum, and demands both logical discipline and imaginative creativity in the selection and design of algorithms, and the writing, testing and debugging of programs. Furthermore, it:

  • relies on an understanding of the rules of language at a simple level
  • encourages an awareness of the management and organisation of computer systems
  • extends the students' horizons beyond the school or college environment in the appreciation of the effects of computer applications on society and individuals

For these reasons, Computer Science is as relevant to a student studying Arts subjects, as it is to one studying Science subjects. 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 well being of the country.

What you will study

The course covers the following two units:

Unit 1 – Fundamentals of Computer Science

Written examination (2 hours) 100 marks - 25% of the qualification 

This unit investigates computer architecture, communication, data representation, data structures, software applications, programs, algorithms, logic, programming methodologies and the impact of computer science on society.

Unit 2 – Practical programming to solve problems

On-screen examination (2 hours) 60 marks - 15% of the qualification

This unit consists of a series of set tasks completed on-screen by candidates.  These tasks will assess the practical application of knowledge and understanding and will require the use of Python as a programming language.
