5. Cambridge Winter Pool

If you're pooled at Cambridge, your real odds of an eventual offer are close to 28% — not the vague "roughly 1 in 4" figure repeated across most admissions advice sites with no year or source attached. In the 2025 cycle, Cambridge placed 4,375 applications into the Winter Pool and made 1,228 offers to pooled applicants, according to the University's own Guide to the Winter Pool (published July 2025) and its Undergraduate Admissions Statistics report for the same cycle. This page sets out those official numbers in full — the school-type breakdown, the five-year trend, and FOI-released Medicine (A100) data — so you can plan the waiting period around real figures rather than forum estimates.

How Does the Cambridge Winter Pool Work? (Quick Overview)

The Winter Pool is Cambridge's process for giving strong applicants a second look at a different college if their first-choice college is oversubscribed in their subject. Being pooled is not a rejection: your original college has told the other 28 colleges that you are a strong candidate it simply couldn't accommodate, and any college can then make you an offer, invite you to a further interview, or (less commonly) decide not to take your application further. For the full step-by-step mechanics — what a pool letter says, what to do while you wait, and how it compares to Oxford's reallocation process — see our complete guide to what happens after an Oxbridge interview, which has a dedicated section on the pooling system. The rest of this page focuses on the numbers behind that process: exactly how many applicants are pooled each year, how many receive offers, and whether the odds differ by school type or subject.

What Are the Exact 2025 Winter Pool Numbers?

Cambridge publishes its Winter Pool figures every year in a short document called the Guide to the Winter Pool, produced by the Cambridge Admissions Office. The most recent edition, published July 2025, states plainly: "4,375 applications were pooled in total" in the 2025 cycle, and "1,228 pooled applicants were made offers." That is an overall pool-to-offer conversion rate of 28.1% — higher than the rough "1 in 4" figure several competitor sites use without citing a year or source. Of the 1,228 offers, 1,207 were made without any further interview and 21 followed a January re-interview. Separately, Cambridge's Undergraduate Admissions Statistics (2025 cycle) report — Table 12.1, "Progress of applicants through the admissions process" — breaks the 1,228 pool offers down by which college made them: 275 were retained by the applicant's original pooling college after reconsideration, and 953 were made by a different college through the pool proper. All 29 undergraduate Colleges pooled applicants that cycle, and the guide notes that "in a typical year, around 3,500 applicants are made offers by their preference/original College, and up to 1,000 applicants are made an offer by another College through the pool" — useful context for how 2025's 953 other-college offers compares to a normal year.

Cambridge Winter Pool Odds by School Type: Who Gets Pooled Offers?

Cambridge's Table 12.1 splits the applicant pool into three categories — Home Maintained, Home Independent, and "All Others" (which includes most international applicants and Home applicants outside the UK school system) — and reports how many from each group were pooled and how many received an offer from a different college. Combining the standard-entry and deferred-entry rows for the 2025 cycle, Home Maintained applicants converted 27.4% of their pooled applications into an out-of-college offer (551 offers from 2,014 pooled), against 18.9% for Home Independent applicants (185 offers from 980 pooled) and 15.7% for the All Others category (217 offers from 1,381 pooled). This is a real, published gap of nearly 12 percentage points between the highest- and lowest-converting groups — a level of detail no competitor page or existing Leading Tuition page currently cites. It's worth noting these figures cover only offers made by a different college; they exclude the 275 offers retained by an applicant's original pooling college, so every group's true pool-to-offer rate (including retained offers) is somewhat higher than the percentages below.

Is the Winter Pool Getting More Competitive? The 2021-2025 Trend

Cambridge publishes Table 12.1 in every year's Undergraduate Admissions Statistics report, which makes it possible to build a genuine multi-year trend rather than quoting a single snapshot. Pulling the "Winter Pooled" and "via Winter Pool" totals from each of the five most recent published cycle reports (2021 through 2025), the share of pooled applicants receiving an offer from a different college has risen steadily: 14.3% in 2021, 16.3% in 2022, 20.5% in 2023, 21.6% in 2024, and 21.8% in 2025. In other words, an applicant pooled in 2025 had a materially better chance of an out-of-college offer than one pooled just four years earlier, even though the number of applications entering the pool each year has stayed roughly flat, between 4,374 and 4,767. Adding in the 275 offers retained by the original pooling college — a split only published for the 2025 cycle — brings the most recent overall pool-to-offer rate to 28.1%, the highest of the five years for which comparable data exists.

What Do Medicine (A100) Pooling Numbers Show?

Cambridge's general Winter Pool guide and admissions statistics reports don't break figures down by subject, so subject-specific data has to come from Freedom of Information requests. A request submitted to the University of Cambridge and answered on 4 October 2024 (FOI reference 2024/859, published via WhatDoTheyKnow) asked specifically for winter and summer pooling offer numbers "split by Overseas and Home domicile categories, with the Home category further split by Independent and Maintained school candidates," by college and subject, across the three most recently completed admissions cycles at the time (2022, 2023 and 2024). For Medicine (A100), the response shows 132 Winter Pool offers to Home-domiciled applicants and 16 to International applicants across those three cycles combined — 148 in total, or roughly 49 per cycle. Within the 132 Home offers, 96 went to Maintained-sector applicants and 35 to Independent-sector applicants. This is the only subject-specific, officially-sourced Cambridge pooling dataset publicly available for Medicine, and it is a considerably lower per-cycle figure than the overall 953-1,228 offers made across all subjects combined — a reminder that Medicine's small cohort size and fixed clinical training places make pooled offers scarcer than in larger subjects like Natural Sciences or Engineering. If you're applying to Cambridge Medicine specifically, see our Cambridge Medical School guide for course-specific admissions detail.

How Rare Is a January Re-Interview?

One of the most-repeated but least-sourced claims about the Winter Pool is the chance of being called back for a further interview. Several admissions consultancy sites cite a "2-5%" re-interview rate without a named source or year. Cambridge's own 2025 figures put the real number much lower: just 38 of the 4,375 pooled applicants — 0.87% — were invited to a January interview. Of those 38, 21 went on to receive an offer, a 55.3% success rate once re-interviewed, while the remaining 1,207 pool offers were made directly from the existing application with no further interview at all. Cambridge's guide describes the process plainly: "a few candidates may be called back for a further interview, but this is rare," and the University schedules any re-interviews for a tight window — the current 2026 pool timetable has candidates "invited, by telephone or email, to attend a second interview" from 16 January 2026 onwards, with all applicants notified of the outcome on 28 January 2026. If you are one of the small number of candidates recalled, our 7-day interview invite preparation plan applies directly — treat the notice period exactly as you treated your first invitation.
