Computer Science

  • Number of students per year: three to five
  • Typical offer: A*A*A or equivalent
  • Essential subjects: A-Level Mathematics
  • Useful subjects: A-Level Further Mathematics, Computing

Computer Science is concerned with the study of how information and data can be manipulated and computed. It increasingly underpins many other disciplines.

The Department of Computer Science and Technology in the University of Cambridge has an excellent track record in attracting some of the best students nationally and internationally. 

Jesus College has taught many students since the Department was founded. We have two Computer Science Fellows who share the role of Director of Studies over the four years of the course, arranging supervisors who include Jesus postgraduate students.

Professor Jean Bacon is the author of books on operating systems and concurrent systems which have been adopted worldwide for teaching these subjects. Professor Cecilia Mascolo is a world leading researcher in mobile systems and is teaching on some very topical subjects such as mobile and sensor systems and social and technological network analysis.

Former Jesus Computer Science students are now working for world leading computing organisations such as Google, Microsoft, and Facebook, as well as universities, financial enterprises, and startups.

Please see the Department of Computer Scinece & Technology web page for more details about the Computer Science course. 

With two female Directors of Studies in Computer Science, we encourage women to apply for our courses at Jesus. The Department has a strong women's group, women@cl.

Our typical conditional offer is two A* grades at A-Level, or equivalent. If you are studying four relevant A-Levels you may be asked for A*A*AA. You don't need to take a Sixth Term Examination Paper (STEP) or Advanced Extension Awards (AEA).

An A-Level or equivalent in Maths is essential. Further Maths A-Level is strongly recommended, if available. A-Level Computing is useful but by no means required. We prefer it if you have had some programming experience or background knowledge of computing either in or outside school, in order to demonstrate your interest and aptitude.

Any other science or arts subjects of a rigorous academic nature including History, languages etc, are welcomed. Information and Communications Technology (ICT) is only relevant as a general background to using computers for any subject, rather than specialist Computer Science, and General Studies is not included in A-Level offers.

When making offers we take into consideration your workload, giving credit for more than three A-Levels, and the level of teaching support available at your school.

Written assessment

Applicants for Computer Science are required to take the pre-interview Cambridge Test of Mathematics for University Admission (CTMUA) at an authorised centre local to them. This assessment will take place on 4th November. For more information, see the University undergraduate Computer Science pages.



In order to minimise COVID-related risks to our applicants, students and staff in the coming undergraduate admissions round, we are making plans to interview applicants this year without requiring them to travel to Cambridge in December. We will release further details about alternative arrangements as soon as we can.

You'll usually have two subject interviews of about 25 minutes each. Both are with two subject specialists and include the Directors of Studies. The aim of the interviews are to explore your aptitude for Computer Science. The interviews will usually include exercises to test the your attitude towards logic, programming, and mathematics.

Written work

You don't need to submit any written work.

Deferred and post A-Level entry

We're happy to consider applications for deferred or post A-Level entry in Computer Science. If you defer we'll ask you about your gap year plans at interview.
