COMPUTER SCIENCE

At the heart of Computer Science lies the notion of computational thinking: a mode of thought that goes well beyond software and hardware, and that provides a f ramework within which to reason about systems and problems.

This mode of thinking is supported and complemented by a substantial body of theoretical and practical knowledge and by a set of powerful techniques for analysing, modelling and solving problems.

CIE-ASSESSMENTS

Paper 3: 25% of A-Level--External exam 1 hour 30 mins.

Computational thinking is further developed at A Level to extend methods for searching, sorting, structuring and storage of data. This is supported by developing an in-depth understanding of how computer architecture, hardware, systems software, security measures and communication systems can have different structures and protocols. This includes understanding of Artificial Intelligence (AI).

Paper 4: 25% of A-Level-- Online exam 2 hours 30 mins.

Programming paradigms are considered together with an extension of programming skills to include recursion and exception handling.
