Mathematics is an exciting and demanding subject. It is represented at Sidney by enthusiastic and supportive academics specialising across a broad range of areas.

Important Note Concerning Interviews for 2024

Please note, all undergraduate admissions interviews at Sidney Sussex for the 2024-25 admissions round will be held online. Further details regarding interview platform will follow.

The Allen Society is the mathematics society at Sidney Sussex that brings together the undergraduates, postgraduates, and Fellows of the College. The society organises social events and each year invites one or two distinguished speakers to give a popular mathematics talk

The society is named after Sir Roy Allen, CBE, FBA (1906 - 1983), who studied mathematics at Sidney Sussex and was later a Fellow. Allen was awarded a Wrangler scholarship for coming top of his year in the Mathematics Tripos. He went on to be a leading economist and statistician, and spent much of his career as Professor of Statistics at the London School of Economics. He was also President of the Royal Statistical Society.

Undergraduate Study

The Cambridge Mathematics course is often considered to be the most demanding undergraduate Mathematics course available in Britain and, correspondingly, one of the most rewarding.  As well as the straight Mathematics course, it is possible to apply to study Mathematics with Physics. Applicants for Mathematics and Mathematics with Physics are considered together.

The Mathematical Tripos is a demanding course, but students at Sidney receive a lot of support from the Directors of Studies. The Directors of Studies oversee students' progress and guide them throughout the academic year. A major part of their role is to arrange supervisions, and Sidney Sussex is lucky to have academic staff covering a broad range of topics taught in the first and second years of the Mathematics Tripos, which means that most supervisions can be taught 'in house'.

The Directors of Studies also arrange both individual and group meetings with students on a regular basis, advise on subject choices and course work, organise informal progress tests and mock exams, and help with revision for the end of year exams.

Mathematics at Sidney is taught in a supportive atmosphere where students are expected to take charge of their own education from the moment they arrive.

Sidney Sussex is among the smaller colleges, and normally admits between 6 and 8 mathematics students each year, resulting in a close-knit group of students who quickly get to know each other.
