ICT A-Level – Computer Science

A Level – WJEC Computer Science


Examination Board: WJEC


Course Aims:

The WJEC AS and A Level in Computer Science encourages learners to develop:

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

Computer science integrates well with subjects across the curriculum. It 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 fundamental level; it encourages an awareness of the management and organisation of computer systems; it extends the learners’ horizons beyond the school or college environment in the appreciation of the effects of computer science on society and individuals. For these reasons, computer science is as relevant to a learner studying arts subjects as it is to one studying science subjects.

The WJEC AS and A Level in Computer Science has been designed to give an in-depth understanding of the fundamental concepts of computer science and a broad scope of study opportunities.

This specification promotes the integrated study of computer science. It will enable learners to develop a broad range of skills in the areas of programming, system development, computer architecture, data, communication and applications.

AS students undertake two units. AS unit 1 examines the fundamentals of Computer Science. Within AS unit 2, students will undertake practical programming to solve problems.

There is no coursework undertaken until students reach A2 level in Year 14. Students continuing to A2 will also explore a number of areas related to computer science including, data structures, logical operations, algorithms and programs, principles of programming, systems analysis, software engineering, program construction and economic, moral, legal, ethical and cultural issues relating to computer science.

The full GCE WJEC Computer Science syllabus can be found on Fronter or WJEC’s website (see https://www.wjec.co.uk/qualifications/computer-science/computer-science-gce/wjec-gce-computer-science-spec-from-2015.pdf?language_id=1).

Careers and Further Study

GCE Computer Science can lead to a wide range of careers including multimedia and website design, software design, games design, computer programming, graphic design, IT management, CAM engineering and CAD design.

An Advanced GCE AS or full A Level in Computer Science combines well with almost all other AS and Advanced GCE subjects.  Taken with Mathematics and Science, it supports applications for any IT-based University courses. Taken with Languages or Arts it supports an equally wide range of university courses such as Communications, Media, Business and Management.
