Psychological and Behavioural Sciences Tripos


Typical offers for the course are A*AA at A Level, or 40–41 points out of 45 with 776 or 777 at Higher Level in the International Baccalaureate. Equivalent qualifications are also considered – see the Undergraduate Study website for details, and contact a College Admissions Tutor for further advice.

From the last two admission rounds for PBS, on average per year 380 applications are received and 80 offers are made.

There are no prerequisite subjects for PBS but maths and biology are both useful. The standard offer is A*AA, but a few colleges (e.g., Downing) make slightly stiffer offers (A*A*A).

How to apply

Admission to the University is managed by the Colleges. Please note that Peterhouse does not accept students for this course. To apply for PBS at Cambridge you can either make an open application or choose a College. To do this, you should first find out as much as you can about the Colleges (e.g. come and visit) and in particular look at the research interests of College fellows associated with PBS. For further guidance see the Undergraduate Admissions website.

You must submit your UCAS application online here by 15 October in the year before you intend to commence the course. Once this has been received, you will be prompted to provide some additional information in a Supplementary Application Questionnaire here (SAQ) direct to the University of Cambridge. If you wish to defer entry, you should indicate this on your UCAS application.

If you have a good examination record and a favourable reference, you're likely to be invited to interview. Interviewers want to see how you work through problems and take on new ideas, and to find out more about you. This is an important part of our selection procedure.

Further information about applying to the University is available from the undergraduate study website.
