Postgraduate applicants to Cambridge often spend much less time thinking about which college to apply to than they might. But the choice of college can make a big difference to your Cambridge experience – and it can be very difficult to change colleges once you arrive. At Peterhouse we work hard to make the postgraduate experience academically and socially enriching. The postgraduate community at Peterhouse numbers around 140, and includes one-year, two-year and three-year students: that is, there are postgraduate students working for the degree of M.Phil and other degree and diploma courses, usually in one year but sometimes in two; and there are those studying for the PhD. The postgraduate students are drawn largely, and from outside the college, and represent a very wide variety of subjects, nationalities and backgrounds.
