Assessment

The IGCSE Computer Science curriculum is typically assessed through a combination of written examinations and practical assessments. The assessment components usually include:

Paper 1: Theory of Computer Science

• A written exam that tests students' understanding of the theoretical aspects of the curriculum, including data representation, hardware and software, networks, and security.

Paper 2: Practical Problem-Solving and Programming

• A written exam or test that assesses students' ability to apply their programming and problem-solving skills to develop algorithms and write code.

Skills Developed

Students studying IGCSE Computer Science will develop a range of skills, including:

• Computational Thinking: Ability to approach problems logically and develop efficient solutions.
• Programming Proficiency: Skills in writing, testing, and debugging code in a high-level programming language.
• Analytical Skills: Ability to analyze data and information to make informed decisions.
• Technical Knowledge: Understanding of computer systems, networks, and security measures.
• Ethical Awareness: Awareness of the ethical and societal implications of computer science.

The IGCSE Computer Science curriculum provides a solid foundation for further study in computer science and related fields, preparing students for future academic and career opportunities in the rapidly evolving world of technology.
