Mathematics and Computer Science BA

3 Years On Campus Bachelors Program

University of Oxford

Program Overview

The BA in Mathematics and Computer Science at the University of Oxford is a powerful combination of analytical mathematics and computational theory. It’s designed for students who enjoy logical reasoning, coding, and tackling complex problems through both abstract thinking and real-world application.

Curriculum structure

Year 1
In your first year, you’ll build a strong foundation in both mathematics and computer science. Mathematics modules include Linear Algebra, Analysis, Probability, and Groups and Group Actions. In computer science, you’ll study Imperative Programming, Functional Programming, Design and Analysis of Algorithms, and Introduction to Proof Systems. This year establishes the essential skills you’ll need for advanced study in both fields.

Year 2
The second year expands your knowledge and introduces more specialised topics. You’ll continue with mathematical modules such as Complex Analysis, Metric Spaces, and Numerical Analysis, alongside computer science courses like Models of Computation, Artificial Intelligence, and Data Structures and Algorithms. You’ll also work on a Group Design Practical, which helps you apply your theoretical understanding to collaborative programming and problem-solving projects.

Year 3
In your final year for the BA, you’ll have the freedom to focus on areas that interest you most. Optional papers may include Machine Learning, Computational Complexity, Graph Theory, Set Theory, Computer Graphics, or Quantum Information. This stage emphasizes independent thought, critical analysis, and innovation — preparing you for both professional and research-oriented roles.

(Optional Year 4 for MMathCompSci)
Students who wish to extend their studies can progress to a fourth year, leading to the integrated master’s degree (MMathCompSci). This year allows for advanced research and in-depth project work, letting you explore topics like advanced machine learning, cryptography, or computational logic at a higher academic level.

Focus areas
Pure and applied mathematics; algorithms and computation; data structures; programming paradigms; artificial intelligence; discrete mathematics; formal logic and systems.

Learning outcomes
Graduates will gain the ability to solve abstract mathematical problems, design efficient computational systems, and understand the theoretical limits of computing. The program nurtures critical thinking, algorithmic design, and analytical problem-solving — equipping students for both research and high-level industry roles.

Professional alignment (accreditation)
Although the program is not professionally accredited, it is highly regarded worldwide for its rigorous academic training. It provides the intellectual foundation for careers in data science, finance, research, software development, and artificial intelligence.

Reputation (employability rankings)
Oxford’s Mathematics and Computer Science degree is globally recognized as one of the most competitive and prestigious programs in its field. Graduates are highly sought after by top employers across technology, finance, academia, and research sectors. The program’s balance of theoretical depth and practical application ensures exceptional employability and long-term career growth.

Experiential Learning (Research, Projects, Internships etc.)

The BA in Mathematics and Computer Science at the University of Oxford offers a uniquely balanced education that connects mathematical logic and analytical reasoning with the creativity and technical skills of computer science. From your very first term, you’ll engage in practical work — writing programs, solving mathematical problems, designing algorithms, and analysing how computation and mathematics intersect in real-world systems. Oxford’s signature tutorial system ensures that your learning is highly interactive and applied, with continuous feedback and problem-based exploration.

Students don’t just study concepts; they use them — through coding assignments, design projects, collaborative problem-solving, and an advanced research or development project in later years.

Here’s how experiential learning is built into this program:

Tutorials and problem classes: Weekly small-group tutorials (typically two to four students) allow you to discuss problem sets, explore proofs, and analyse algorithms directly with expert tutors.
Hands-on programming: You’ll gain practical coding experience across multiple paradigms, including functional and imperative programming, applying these skills to solve algorithmic challenges and model real-life systems.
Group design project: In the second year, you’ll take part in a collaborative software design project that mimics professional computing work — from planning and implementation to testing and presentation.
Individual project or dissertation: If you progress to the fourth-year variant (MMathCompSci), you’ll undertake a substantial independent project that integrates mathematical reasoning with computational design or research.
Applied algorithm design and analysis: Modules on algorithmic efficiency, logic, and computation focus on real application through practical exercises and analytical assessment.
Interdisciplinary coursework: The program combines both pure and applied elements — such as machine learning, quantum computing, computational complexity, and topology — encouraging you to apply mathematical concepts directly to computing problems.
Computing laboratories and digital tools: Students make use of advanced computing environments and software for programming, modelling, and testing systems throughout their degree.
Collaborative academic environment: The Mathematical Institute and Department of Computer Science provide access to lectures, research seminars, and problem-solving workshops that keep you engaged with current developments in both fields.

By the end of your studies, you’ll have developed a rare combination of theoretical depth and practical skill — able to think rigorously, code effectively, and design innovative computational solutions grounded in mathematical logic and analysis.
