Course summary

Computer Science A Level is the science of how computers work and therefore the course covers both the practical and theoretical sides of computing. Problem solving and innovation are at the heart of the Computer Science A Level and form the basis of how we learn to create programs and develop algorithms. The theoretical side of the course looks at the inner workings of a computer and you will study data representation as well as look at components such as the CPU, RAM, and internal registers. 50% of the final examination covers the theory element of the course; you will find it helpful if you are already familiar with a programming language for the other 50%. A large portion of the course is programming-based. A key part of the A Level is object-oriented programming, a common approach to programming in business and commercial situations. The course promotes good programming practices such as modularisation, sensible naming conventions, proper commenting, and much more. As you learn how to program you will learn the relevant computer architecture, such as how computers store and represent different data types, including images, videos, and sounds. You will also learn about networking protocols, and study the moral, ethical, legal, and cultural issues and opportunities surrounding computers.
