Psychological and Behavioural Sciences

Psychological and Behavioural Sciences is a three year degree course covering a broad range of psychology, including behavioural and cognitive neuroscience, cognitive psychology, developmental psychology, social psychology, as well as the study of atypical development and adult psychopathology.

Why study Psychology at Christ's?

Students are hugely positive about their experiences studying this subject at Christ’s, not just because of our College’s friendly community feel, but because we offer excellent tutorial and cross-college support.

Undergraduates can join active research groups, such as the behavioural science lab and field studies run by Christ’s Director of Studies, Professor Theresa Marteau. These look at how changing behaviour can improve population health and are widely popular with students.

PBS graduates to date have gone on to study for further degrees, or to work as research or care assistants with a view to training as clinical psychologists. Information about becoming a psychologist is available on the British Pscyhological Society website.

Course content and structure

The PBS course (or ‘tripos’) is a three-year degree. Please visit the University website for full details of the Psychological and Behavioural Sciences course content and structure.



You attend lectures at the Department of Psychology, just a short walk away from Christ’s (see map). You also have weekly ‘supervisions’ here in College. These small-group (or one-to-one) tutorial sessions are arranged by your Director of Studies and give you the advantage of personally-tailored guidance and tuition from an experienced supervisor. And our modern library is designed to ensure you get the peace you need without feeling isolated when you’re studying independently.

Christ’s Director of Studies for PBS is Professor Theresa Marteau, who is Director of the University’s Behaviour and Health Research Unit.

Dr Camilla Nord is a Bye-Fellow of the College and a supervisor in Psychological and Behavioural Sciences.

"Out of all of my papers this year, I thought that the most interesting essay I got to work on was either one on social norms, or another on non-traditional families, as I enjoyed being able to explore ongoing research."


How to Apply

Visit How to Apply for full details and a timeline of the application process. We welcome applicants from all backgrounds and school types, all over the world. If you're applying from outside the UK, please read our international students section.

Subject requirements

There are no specific subjects that you must be studying at school to make an application for PBS, though students with A-level, IB Higher (or equivalent) Mathematics and/or a science subject may be more competitive than those without. We do not require you to be studying Psychology at school.


If we invite you for interviews, these usually take place in early December. Those invited for Cambridge interviews are normally interviewed for 35-50 minutes in total. At Christ’s, we usually split the time into two interviews with academics in Psychological and Behavioural Sciences. During one of these, we’ll ask you to interpret a graph, solve a problem or comment on an essay question. 

For an idea of what to expect, please read the information and watch the short films on Cambridge admissions interviews.

We also hold interviews in a number of locations overseas. If this may be relevant for you, please see the international students section.

There will be no Admissions Assessment taken at interview for Psychological and Behavioural Sciences at Christ's College.


Christ's College does not have fixed quotas of places for different subjects and the exact numbers admitted in any one year will depend upon the strengths of the fields of applicants in various subjects. However, our aim is to make around three offers each year for PBS. 

Our typical conditional offer for PBS is A*AA at A level, 42 points overall in the IB with 7,7,6 in relevant Higher Level subjects, or the equivalent in other qualifications. If you are an international applicant taking another qualification, do look at the international students section for further information. If you apply after you have finished school and we give you the offer of a place, it will not normally have further academic conditions if you have already met our requirements. Further information is given on our page for post-qualification applications.
