COMPUTER SCIENCE

Examination Board: OCR Cambridge

OCR’s GCSE (9–1) specification in Computer Science encourages learners
to be inspired, and challenged through completing a coherent, satisfying
and worthwhile course of study. It will prepare learners to make informed
decisions about further learning opportunities and career choices. The aims
and learning outcomes of the OCR’s GCSE (9–1) in Computer Science are to
enable learners to:
• understand and apply the fundamental principles and concepts
of Computer Science, including abstraction, decomposition, logic,
algorithms, and data representation
• analyse problems in computational terms through practical experience
of solving such problems, including designing, writing and debugging
programs
• think creatively, innovatively, analytically, logically and critically
• understand the components that make up digital systems, and how they
communicate with one another and with other systems
• understand the impacts of digital technology to the individual and to
wider society
• apply mathematical skills relevant to Computer Science.
• Assessment consists of two papers, one focusing on the theory of
Computer Science and one with a focus on programming and algorithms.
Both papers have identical weighting and mark allocations.
