Introducing BSc Computer Science and Mathematics

Mathematics forms the foundation of computer science. With the increasing scale of computing systems, and growing volumes of data, we are developing and using more sophisticated mathematical techniques every day.

This programme aims to give you a thorough understanding of mathematics and computing to allow you to operate at the cutting edge of:

  • computer and data science
  • machine learning
  • artificial intelligence

We offer a wide range of courses delivered by leaders in their field. You will have the flexibility to focus on the areas of computer science, artificial intelligence and mathematics that interest you most.

(Revised 15 April 2024 to remove the ‘Only apply to one Informatics programme’ section from the introduction)

All of our programmes start with a common core of mathematics courses and informatics courses, with increasing choices for specialisation in later years depending on your interests. In a joint degree, you will also have to take compulsory courses in your second subject.

Each year you will have 120 credits worth of courses spread across two semesters. Some of these credits will go into compulsory courses and the remaining can be used on optional courses. Optional courses may be in schools outside the School of Informatics.

Please note this is an overview: courses may be subject to change.

What are my choices for going abroad?

How will I learn?

Computer science teaching

You will be taught by leaders in their field through a combination of:

  • lectures
  • tutorials
  • practical classes

In later years, you will spend more time working on projects that involve:

  • building computer systems from scratch
  • developing systems
  • doing experimental work
  • working on projects with guidance from a supervisor

Mathematics teaching

In Year 1, mathematics lectures are usually interactive. Lecturers use online voting systems and encourage small group discussion to improve your understanding of core material.

In later years, lectures follow a more 'traditional' lecturing style but occasionally include the voting system.

Mathematics lectures are supported by small group teaching workshops. These sessions give you an opportunity to apply the concepts you learn in lectures and develop your understanding. You will work with five to six other students, with a tutor on hand to support you and answer questions.


Students in the School of Informatics have access to services that support their learning, particularly in the beginning of their degree.

InfPALS is a peer support service for Year 1 students focusing on material covered in courses and also general topics related to informatics.

InfBase is a drop-in help desk for Year 1 and 2 students to get additional tutoring and support with their courses.

You will also be invited to join:

  • CompSoc, a tech society which offers a varied programme of events
  • Programming Club, to get more practical programming experience

Pastoral support is offered by the Informatics Student Support Team.

You will have access to the following support in the School of Mathematics:

  • drop-in mathematics support in Year 1
  • option to take part in the peer-assisted learning scheme, MathPALS
  • Mathematics Student Services Team

How will I be assessed?

Computer science assessments

In the School of Informatics you will be assessed by:

  • coursework assignments
  • larger projects
  • exams

You will undertake some project work individually and some with other students.

You will complete a large individual project in your final year.

Mathematics assessments

Mathematics courses are mostly assessed through exams. In Years 1 and 2, these exams are primarily 'open book' exams, where you can use your textbook and notes. This allows you to concentrate on understanding and using the ideas and concepts involved, rather than memorising procedures.

In later years, there is a mixture of open and closed book exams, depending on the course.

Most mathematics courses have regular assessments throughout the year, both written and online, so you can get feedback on your progress. These typically count for a small part of your course grade.

Later in the degree, there are some courses available which are entirely assessed by coursework, usually in the form of reports, posters, projects or presentations.

We normally make offers to the highest qualified applicants. If competition for places is high this may mean that offers will only be made to applicants who are predicted, or who have achieved, above the single set of grades or the upper grade level in a range. Any conditional offer made may require you to achieve grades above the upper grade level. Therefore, achieving the top of our standard entry requirements does not guarantee a place on the relevant degree.

Please apply for only one Computer Science degree as we are only able to consider one application to this subject area.
