How can mathematics help us understand the dynamics of infectious diseases? Or how an idea circulates on social media? Or the behaviour of queues? We’ll show you how mathematics solves real-world problems. You’ll work with experts whose research is having an impact – from forecasting local outbreaks of COVID, to predicting floods.
In your first year, you’ll explore the basics of mathematics. This includes analysis and linear algebra, as well as an introduction to computational mathematics. In your second year, you’ll add probability and statistics. In your third and fourth year, you then build on your existing knowledge and discover new aspects of the subject including:
- mathematical biology
- cryptography
- probability
- financial mathematics
- partial differential equations.
You also explore a topic of your choice in the MMath project in your final year.
This course is flexible, so you can focus on what fascinates you while gaining a strong foundation in core mathematics. You’ll develop your analytical and modelling skills using industry-standard software such as MATLAB, Python and R. You’ll also have the opportunity to apply for a placement, where you can gain experience working with a company.
Our Department is a close-knit community, and you’ll get to know your lecturers on an individual basis. Their dedication and support will help you to get the most from your degree. Academic advisers support you every step of the way and you’ll have lots of opportunities to engage with potential employers. You’ll also have a dedicated careers advisor.
During integrated Masters year, you’ll develop new mathematical skills and knowledge – particularly relevant if you’re interested in going on to a research career, or into specialised fields including data science, finance or mathematical modelling.

Your modules
Core modules
Core modules are taken by all students on the course. They give you a solid grounding in your chosen subject and prepare you to explore the topics that interest you most.
Autumn teaching
Spring teaching
We regularly review our modules to incorporate student feedback, staff expertise, as well as the latest research and teaching methodology. We’re planning to run these modules in the academic year 2025/26. However, there may be changes to these modules in response to feedback, staff availability, student demand or updates to our curriculum. We’ll make sure to let you know of any material changes to modules at the earliest opportunity.
We’ll do our best to provide as much optional choice as we can, but timetabling constraints mean it may not be possible to take some module combinations. The structure of a small number of courses means that the order of modules or the streams you choose may determine whether modules are core or optional. This means that your core modules or options may differ from what’s shown here.
