AS Course Outline

What is AS Computer Science?


Computer Science encompasses the theoretical aspects of how a computer is designed, used and applied to solve real world problems. It is an applied subject that provides the student with practical problem solving skills in a variety of programming language. It provides a strong foundation for students who wish to enter a career in Computer Science as Programmers, Data Analysts, Cyber Security Consultants, Web Designers, Games Developers or Electronic Engineers. It is aimed at students who see themselves as developing their own computer software and hardware.

Students will learn the fundamental principles and workings of machine architecture, systems software, applications software, algorithms and programming.

There is no coursework element in AS Computer Science although the Unit 2 exam does expect students to learn how to formulate algorithms and apply them in a procedural language which will be used to complete the A-level coursework in the second year.

What Skills Will Students Develop When Studying Computer Science?

What are the Entry Requirements for AS Computer Science?

The course requires students to possess a good command of English together with a highly developed sense of logic, and a rigorous approach to problem solving. Students wishing to study Computer Science should ideally possess B grades or higher in GCSE Mathematics and English. It would be advantageous if a student has studied Computer Science or a related subject at GCSE. AS Computer Science students should have ideally encountered basic computational thinking and programming as a leisure interest or within their secondary education.
