GCSE & IGCSE Academics

The IGCSE Computer Science course offered by Edexcel introduces students to the fundamentals of computing, programming, and the principles of computer systems. The syllabus covers both theoretical knowledge and practical skills, providing a strong foundation for further study and careers in computer science and related fields.

The assessment consists of two written examination papers:

• Paper 1 - Principles of Computer Science (1 hour 40 minutes): This paper assesses the theoretical aspects of computer science, including data representation, hardware, software, networks, and cybersecurity. It consists of multiple-choice, short-answer, and extended-response questions. It accounts for 50% of the total grade.
• Paper 2 - Application of Computational Thinking (2 hours): This paper focuses on practical problem-solving and programming skills. It includes tasks that require students to design algorithms, write code, and solve computational problems. This paper contributes the remaining 50% to the total grade.

Both papers evaluate students' understanding of computer science principles and their ability to apply theoretical knowledge to practical scenarios.

The IGCSE Computer Science course aims to equip students with a comprehensive understanding of computer science concepts and the ability to develop and implement algorithms. It provides essential skills for further studies in computer science and prepares students for the technological challenges of the modern world.

The Cambridge IGCSE Computer Science syllabus develops students' understanding of computational thinking and how computer-based systems operate. Topics include data representation, data transmission, computer hardware, software, the internet, cybersecurity, automated and emerging technologies, algorithms, programming, databases and Boolean logic. Students learn to analyse problems, design algorithms and create logical programming solutions.

The assessment consists of two papers:

• Paper 1 - Computer Systems: 1 hour 45 minutes, 75 marks and 50% of the total grade. It contains compulsory short-answer and structured questions covering data representation, communication, hardware, software, the internet and emerging technologies.
• Paper 2 - Algorithms, Programming and Logic: 1 hour 45 minutes, 75 marks and 50% of the total grade. It contains compulsory short-answer, structured and scenario-based questions covering algorithms, programming, databases and Boolean logic.

The AQA GCSE Computer Science syllabus develops students' understanding of computational thinking, programming and the technologies behind modern computer systems. Students study algorithms, programming, data representation, computer systems, networks, cybersecurity, relational databases, SQL and the ethical, legal and environmental effects of digital technology. The course develops logical reasoning, problem-solving and practical programming skills.

The assessment consists of two written papers:

• Paper 1 – Computational Thinking and Programming Skills: Covers algorithms, programming, code tracing, problem-solving and the designing, writing, testing and refining of computer programs. The examination is 2 hours, worth 90 marks and accounts for 50% of the GCSE.
• Paper 2 – Computing Concepts: Covers data representation, computer systems, networks, cybersecurity, relational databases, SQL and the wider impacts of digital technology. The examination is 1 hour 45 minutes, worth 90 marks and accounts for 50% of the GCSE.

Questions include multiple-choice, short-answer, longer-answer, programming, SQL and extended-response tasks. Students are also expected to gain practical experience in designing, writing, testing and improving programs using an approved programming language.

Important: This assessment structure applies to the updated specification first taught from September 2025, with its first examinations in summer 2027. AQA's earlier specification had its final examinations in 2026.
