Computer Science A Level at Clitheroe Royal Grammar School

Course description

AQA AS / A-Level Computer Science

The new AQA A-Level syllabus is assessed by two exams at the end of Year 13 worth 80%, plus 20% awarded for a practical project. The first of the exams involves editing a computer program and writing new instructions as part of a practical exam on the computer.


Note: AS Level is a stand-alone qualification which does not count towards the overall A Level grade.

Course content

AS Level Computer Science consists of two units:

1.    Programming; Data Structures; Problem-solving; Theory of Computation (50% of AS Level)

2.    Data Representation; Computer Systems; Computer Organisation and Architecture; Consequences of Uses of Computing; Communication and Networking (50% of AS Level)

A Level Computer Science consists of three units:

1.    Programming; Data Structures; Algorithms; Theory of Computation (40% of A Level)

2.    Data Representation; Computer Systems; Computer Organisation and Architecture; Consequences of Uses of Computing; Communication and Networking; Databases; Big Data; Functional Programming (40% of A Level)

               3.     Practical Project (non-exam, 20% of A Level)

Entry requirements

Grade B in GCSE Maths and Grade C in GCSE English.

Further information

The course is aimed at all students, whether or not you have studied ICT or Computing at GCSE. We do not assume any previous experience of programming and we will start from scratch. Students who enjoy problem solving often thrive in Computing and the syllabus has some overlap with Maths (number bases) and Physics (logic gates and Boolean algebra).


This course will cover problem-solving and using a computer to help with problem-solving tasks. It will include some advanced electronics, logic circuits, truth tables, systems control, robotics and artificial intelligence, finite state machines, algorithm design, relational databases, systems analysis, data structures and networking. The biggest emphasis will be learning how to write computer software. There will be a large amount of direct hands-on experience, using modern microcomputers together with industry-standard software. The computer rooms at the York Street site contain 90 networked computers running Windows 7 and MS Office 2013 as standard, all with Internet access. Each student will use their own network station for practical work.


This course does not include learning to use ICT packages such as word processors, desktop publishing and spreadsheets.


The area of computing and computer science is an exciting one, with major advances taking place in the development of both hardware and software. In recent years, several of our students have gone on to study computing related courses at Cambridge University, as well as degrees elsewhere in subjects such as computer science, software engineering and games programming.
