Perhaps I'm being really myopic, but where does that page make mention of GCSE grades? As it goes, Oxford does suggest a benchmark figure for GCSEs at A* for medical applicants, but not for English Language and Literature, which is what the OP was thinking of applying for. Besides which, Medicine is a strange fish; its admissions requirements can't really be extrapolated to other degrees anywhere else, either.(Original post by VirgoStrain)
Oxford medicine entry stats
I assume that if this is the case for medicine applicants, then someone without a single A* and mostly B's and C's doesn't stand a chance, no matter how irrelevant the course they apply to it.
As it goes, I know a number of people who got in with fewer than six A*s at GCSE, so the suggestion that 'Not a single person with less than 6 A*'s got an offer' is incorrect. I agree that it's not all that likely the OP would get an offer; competition is very stiff, and most applicants will have higher grades than that, but it's possible to say as much without dragging irrelevant stats into the picture.
But did you bother to watch?
