Cambridge has 31 colleges, and you'll be asked to choose your top two preferences on the application form. This system confuses virtually every international applicant. Here's how it actually works and why it matters more than you think for your daily life.
Unlike most universities where you belong to a single institution, Cambridge is a federation of 31 independent colleges plus the central university. Your department handles your academic teaching and supervision. Your college handles your housing, social life, meals, pastoral care, and a significant chunk of your daily experience.
Think of it this way: the university is where you work. The college is where you live, eat, socialize, and belong. Every student and academic at Cambridge is a member of both the university and one specific college.
Each college has its own buildings, dining hall, library, chapel, accommodation, grounds, traditions, culture, and financial resources. Some colleges are medieval foundations dating to the 1200s. Others were established in the 20th century. The differences between them are real and affect your daily quality of life.
On the Cambridge application form, you list your first and second choice colleges. You can also select "open application" to let the university assign you. If neither of your chosen colleges accepts you, you may be "pooled" to another college that has available places.
The single biggest practical difference between colleges for postgraduates is housing. Some colleges guarantee accommodation for the full duration of your degree. Others only guarantee the first year. Given Cambridge's tight rental market, this is a significant consideration. Check each college's accommodation policy for graduates before choosing.
Wealthier colleges (Trinity, King's, St John's) can offer better facilities, more funding opportunities, and cheaper accommodation. Less wealthy colleges may have fewer perks but often compensate with a stronger sense of community. As a Gates scholar, your core funding is secure regardless of college, but additional grants for conferences or travel may be college-dependent.
Peterhouse (1284), Trinity, King's, St John's, Clare, Pembroke. Stunning architecture, deep traditions, large endowments. Can feel intimidating at first.
Darwin, Wolfson, Clare Hall, Hughes Hall, St Edmund's, Lucy Cavendish. These colleges have a high proportion of graduate students, which means a more mature community and often better graduate facilities.
Churchill, Robinson, Fitzwilliam, Girton. Modern campuses, often with more space and better accommodation. Less central but quieter.
Emmanuel, Downing, Corpus Christi, Queens'. Walking distance to everything. Active social scenes. Popular with international students.
While Gates scholars are spread across all colleges, several colleges are particularly popular: Darwin (graduate-only, warm community), King's (progressive, central, iconic), Trinity (enormous resources), Churchill (STEM-friendly, modern), and St John's (large, wealthy, excellent facilities). But the "best" college is genuinely the one that fits your personality and needs.
Some colleges are right in the city center (5 min walk to everything). Others are 15-20 minutes by bike. In Cambridge, this matters less than in a big city because everything is close — but in winter, a 20-minute bike ride in the rain feels longer than you'd think.
Most colleges host "formal halls" — candlelit dinners in medieval dining rooms with gowns. The frequency and formality varies by college. Some hold them nightly; others weekly. If this sounds appealing (or horrifying), factor it into your choice.
Larger colleges (Trinity: 1,000+ students) offer more diversity but can feel impersonal. Smaller colleges (Corpus Christi: ~500) are tighter-knit but have fewer events and resources. Graduate colleges hit a sweet spot for many postgrads.
Cambridge colleges often have stunning gardens, sometimes right on the River Cam. If having green space and punting access matters to your mental health during a PhD, consider colleges with extensive grounds (King's, Trinity, St John's, Clare).
Each college has its own sports teams, gym (quality varies enormously), and sometimes its own boathouse. If you're serious about rowing, rugby, or any sport, check what your college offers. The university-level facilities are available to all students regardless.
Here's the honest truth: most students end up happy at their college, even if it wasn't their first choice. Your department, your research, and the Gates community will define your Cambridge experience more than your college. The college choice matters, but it's not worth losing sleep over.
Your college is your home base, but Cambridge itself is a small, beautiful, and unique place to live.
