places during three years, contrasted with 1,220 from 2,900 other schools. To allow a more personalised judgement of students, who might otherwise apply for both, undergraduate applicants are not permitted to apply to both Oxford and Cambridge in the same year. The only exceptions are applicants for organ scholarships and those applying to read for a second undergraduate degree. Oxford has the lowest offer rate of all Russell Group universities. Most applicants choose to apply to one of the individual colleges. For undergraduates, these colleges work with each other to ensure that the best students gain a place somewhere at the university regardless of their college preferences. For postgraduates, all applicants who receive an offer from the University are guaranteed a college place, even if they do not receive a place at their chosen college. Undergraduate shortlisting is based on achieved and predicted exam results, school references, and, in some subjects, written admission tests or candidate-submitted written work. Approximately 60% of applicants are shortlisted, although this varies by subject. If a large number of shortlisted applicants for a subject choose one college, then students who named that college may be reallocated randomly to under-subscribed colleges for the subject. The colleges then invite shortlisted candidates for interview, where they are provided with food and accommodation for around three days in December. Most undergraduate applicants will be individually interviewed by academics at more than one college. Students from outside Europe can be interviewed remotely, for example, over the Internet. Undergraduate offers are sent out in early January, with each offer usually being from a specific college. One in four successful candidates receives an offer from a college that they did not apply to. Some courses may make "open offers" to some candidates, who are not assigned to a particular college until A Level results day in August. The university has come under criticism for the number of students it accepts from private schools; for instance, Laura Spence's rejection from the university in 2000 led to widespread debate. In 2016, the University of Oxford gave 59% of offers to UK students to students from state schools, while about 93% of all UK pupils and 86% of post-16 UK pupils are educated in state schools. However, 64% of UK applicants were from state schools and the university notes that state school students apply disproportionately to oversubscribed subjects. The proportion of students coming from state
