International GCSE Computer Science helps you to develop an interest in computational thinking and an understanding of the principles of problem-solving using computers. You will apply this understanding to create computer-based solutions to problems using algorithms and a high-level programming language. You will also develop a range of technical skills, and
the ability to effectively test and evaluate computing solutions.

Studying International GCSE Computer Science helps you appreciate current and emerging computing technologies, the benefits of their use and recognise their potential risks. It provides an ideal foundation for progression to International AS & A Level and is valuable for other areas of study and everyday life. (Cambridge Assessment International Education, n.d.)

International GCSE Computer Science requires about 130 hours of study. The number of hours needed may vary depending on your previous experience of the subject.

We recommend that students who are beginning this course should have previously completed a Computer Science curriculum such as the International Lower Secondary programme or equivalent national educational framework.

The aim of the International AS & A Level Computer Science course is to encourage you to develop an understanding of the fundamental principles of computer science and how computer programs work in a range of contexts.

You will study topics including information representation, communication and Internet technologies, hardware, software development, and relational database modelling. As you progress, you will develop your computational thinking and use problem solving to develop computer-based solutions using algorithms and programming languages. Studying International AS and A Level Computer Science will help you develop a range of skills such as thinking creatively, analytically, logically and critically. You will also be able to appreciate the ethical issues that arise with current and emerging computing technologies. (Cambridge Assessment International Education, n.d.)

International AS Level Computer Science requires about 180 hours of study, and International A Level Computer Science requires about 360 hours of study. These figures are for guidance only. The number of hours needed may vary depending on your previous experience of the subject.

We recommend that students who are beginning this course should have previously completed an International GCSE course in Computer Science.

Grade B/6 or above in Computer Science at IGCSE (or equivalent) is required before starting International AS & A Level Computer Science. It is also necessary that all A-Level students have IGCSE English Language or the equivalent at Grade C/4 or above.
