A LEVEL
COMPUTER SCIENCE

OVERVIEW Imagine being at the forefront of the technology shaping our future - from designing
smart cities and revolutionising healthcare with AI to cracking the code on climate
change. Computers have transformed the world like no other invention, empowering us
to solve problems and think in ways that were once unimaginable. A level Computer
Science offers you the chance to be part of this revolution. Throughout the course,
you’ll explore key concepts that will open up new ways of thinking and help you master
the subject. Skills like computational thinking, programming paradigms, and
understanding computer architecture will become second nature, preparing you for
higher education and beyond. The ability to link different aspects of the subject
together and apply your knowledge in new situations will give you a clear edge.

APPROACH Our course embraces a student-centred philosophy. Teachers act as facilitators, guiding
and coaching you as you take control of your own learning. You’ll engage with practical
projects that bring together different strands of the subject, encouraging independence,
collaboration, and creativity.
Learning extends beyond the classroom. Coding clubs, competitions, the Cyber EPQ,
and collaborative projects all offer ways to broaden your experience and apply your
skills. Expect to be challenged and supported as you grow into a confident
problem-solver, ready to tackle both academic study and real-world innovation.

COURSE OUTLINE The programme balances theory and practical programming, running in parallel across
two years:
Unit 1: Principles of Computer Science
Computer systems, data representation, networks, encryption, problem-solving
Enabling technologies including Artificial Intelligence (AI)
Assessment: written/onscreen exam (1 hr 30 mins, 80 marks, 25%)
Unit 2: Practical Programming and Problem-Solving
Programming, data handling, algorithms, program design and clean code
Assessment: practical programming exam (3 hrs, 80 marks, 25%)
Unit 3: Advanced Principles of Computer Science
Computer systems, cybersecurity, programming languages, data structuring,
problem-solving
Emerging technologies and professional practice
Assessment: written/onscreen exam (1 hr 30 mins, 80 marks, 25%)
Unit 4: Advanced Practical Programming and Problem-Solving
Advanced programming paradigms, recursion, algorithms, large-scale problem-solving
Assessment: practical programming exam (3 hrs, 80 marks, 25%)
Key themes throughout include computational thinking (abstraction, decomposition,
algorithms), program design, and linking theory with practice.

FURTHER INFORMATION Computer Science is about far more than just coding - it’s about changing the world.
Whether your ambition is to build the next generation of apps, help scientists fight
disease, or design systems to combat climate change, this course will give you the
knowledge and skills to make an impact.
Computer Science pairs brilliantly with subjects such as Mathematics, Physics,
Economics, or Philosophy, and opens doors to careers in AI, software engineering,
cybersecurity, data science, and beyond.

ENTRY REQUIREMENTS You should have a genuine interest in Computer Science and problem solving. Maths 7
(A) is required for all applicants. If you have studied Computer Science at GCSE, a 6 (B)
in Computer Science is required. The free Harvard CS50x Python course is highly
advisable pre-course preparation, especially for students new to the subject.
