The Cambridge winter pool, and what happens in January
Around a fifth of Cambridge offers are made in January, to applicants whose first College did not have room for them. Cambridge does not tell you that you are in the pool. This page sets out what the University publishes about it, checked on 27 August 2026 against its own pages.
What the winter pool is
If you applied in October and were interviewed in December, your application may be put forward to be considered by other Colleges in January. That is the winter pool, in the University's own words. A College that likes an application it cannot make an offer on passes it to the other Colleges rather than turning it down.
Cambridge is explicit that if you are placed in the winter pool, you will not be told in advance. Some applicants learn of it when a different College invites them to a January interview. Others are made an offer by a College they never applied to. Many are never told at all.
What the numbers actually say
These are the University's published figures for the 2025 cycle, which covers applications for entry in 2025 and deferred entry in 2026. They are the most recent outcome figures Cambridge has released.
- 4,375 applications were placed in the winter pool.
- 953 of them received an offer through the pool.
- That is 19.5 per cent of every offer Cambridge made that cycle, and 21.8 per cent of the applications that went into the pool.
Separately, and for the following cycle, Cambridge says around 18 per cent of applications received in October 2025 were placed in the winter pool. The two figures describe different years, so they are worth reading apart.

The dates you have to keep free
These are the University's published dates for 2027 entry.
- 7 to 18 December 2026. The main interview period.
- Around mid to late January 2027. Winter pool interviews.
- Mid-March to early April 2027. Mature applicants who applied in the January round.
The January window is the one families do not plan for. A pooled applicant can be invited to an additional interview at a different College with little notice, in the middle of mock exams, having assumed in December that the process was over.
What a January interview is actually asking
The subject content is the same as December. What changes is who is across the table. These are academics at a College you did not apply to, reading your application for the first time, deciding whether they want to teach you for three years.
Two things follow from that. Your answer to why you applied to your original College is no longer the question being asked, so an answer built around that College lands badly. And whatever you were weak on in December is on the record in front of them, because your December interviewers wrote it down.
The useful preparation between the two is narrow: work out what went wrong in December while you still remember it, and practise being taught by a stranger. Cambridge interviews are supervisions in miniature, and the thing being measured is whether you move when you are pushed.
Where we come in
We run one-to-one interview practice with tutors who sat Cambridge and Oxford interviews themselves, in the subject you applied for. Every tutor is interviewed by us, subject-verified, and holds an enhanced DBS certificate checked against the children's barred list before they teach anyone.
We publish no success rate. Nobody in this market can evidence one, our own included, and a number we cannot show you the working for is worth nothing to a parent deciding in January.
