Mathematics and Computer Science

Mathematics and computer science at the University of Oxford is one of the most intellectually demanding undergraduate programmes in the world. The two disciplines are deeply connected: computer science emerged from mathematics, and the most important advances in computation, from the theory of algorithms to machine learning and cryptography, rest on mathematical foundations. Studying them together at Oxford means engaging with both at their deepest level, in an environment where the tutorial system challenges you to think with rigour and independence from the very beginning.

This programme is available as either a three-year or four-year degree, the longer version offering the opportunity to go deeper into the material and to pursue a more extended project. You will study pure mathematics, including analysis, algebra, and discrete mathematics, alongside computer science topics such as algorithms, programming language theory, computer architecture, and artificial intelligence. The Oxford approach to both subjects is highly theoretical, emphasising mathematical proof, formal reasoning, and the conceptual foundations from which practical techniques derive their validity.

The typical tariff of 216 points reflects the exceptional level of academic preparation the programme demands.

Graduates from mathematics and computer science at Oxford are among the most sought-after in the world. Careers include software engineering, algorithm design, quantitative finance, cryptography, artificial intelligence research, academic research, and technology leadership. Many graduates go on to doctoral programmes at leading universities, including Oxford itself, or join the research laboratories of major technology companies.

The combination of mathematical depth and computational sophistication gives Oxford graduates a genuine advantage in roles that require not just technical skill but fundamental understanding of why things work.
