The most exclusive of Oxford colleges, All Souls College is unique by virtue of having no undergraduates. Instead, entry is only granted to
past winners of the Triwizard Tournament the select few people known as Examination Fellows (or Prize Fellows).
In order to become an Examination Fellow, one has to sit for a written examination, consisting of four papers lasting three hours each. Unfortunately for clinician-scientists like me, these papers normally cover specialist subjects like Classical Studies, Law, History, English Literature, Economics, Politics, or Philosophy i.e. subjects which I now very little about!
In the past, there also used to be a fifth paper consisting of only a single word. Candidates then had to write an essay in response to the chosen word. Crazy, huh?
