Department of Mathematics

Undergraduate study

At Sussex we recognise that mathematics is the foundation of the physical sciences. It plays a major role in the life sciences and in such disciplines as economics, computer science and psychology.

We are ranked 1st in the UK for graduate prospects (The Guardian University Guide 2019, The Complete University Guide 2019 and Times/Sunday Times University Guide 2018). 97% of our students said they were satisfied with being able to contact staff when needed (Unistats 2017) . Mathematics at Sussex is ranked 11th in the UK in The Guardian University Guide 2019.

Our fantastic social and study spaces


BSc student Claire talks about the unique environment and student study spaces within the Department.

A degree in mathematics tells an employer you have acquired a range of advanced mathematical and statistical techniques. Equally important, it shows that you have the ability and commitment to master intellectually difficult problems and that you have been trained in problem solving skills.

Who are we? 

Maths department group facultyDepartment of Mathematics faculty

We are an international department, with experience of research and teaching worldwide. Our lecturers bring their passion for mathematics to our students at all levels. See our People and Contacts page for their profiles. We teach in a variety of methods. Read about our teaching methods.

Who are our students?

We attract a good balance of male and female students, all of whom - from undergraduate courses through to masters and PhD students - are an integral part of our Department and are involved in a number of committees, societies and research seminars.

What do we offer?

We offer a range of courses for all levels and a number of courses with a minor subject, such as Economics. Our popular MMath four year degree is available with a Research Placement – this is an exciting opportunity to develop your research skills working closely with a member of the teaching faculty over the summer and students will receive a bursary for this.

MMath or BSc? 

The MMath courses are aimed at students who have a strong interest in pursuing a deeper study of mathematics and who wish to use it extensively in careers where advanced mathematical skills are important, such as mathematical modelling in finance or industry, advanced-level teaching or postgraduate research. 

Applicants unsure about whether to do an MMath or a BSc are strongly advised to opt initially for the MMath course. If your eventual A level grades meet the offer level for a BSc but not an MMath we will automatically offer you a place on the BSc course. Students on the MMath course can opt to transfer to the BSc at the end of the second year. The two courses start to differ from Year 3 onwards.
