Firstly, my apologies to the OP for being led out of sync from this thread. Ordinarily speaking, I’ve nothing to contribute in a thread like this one but I did take exception to a particular phrase here which says, “Everyone at Oxford is the brightest and most able…” - presumably in their chosen fields.
Don’t know about you guys, but to me this means that no one else in the world comes anywhere near the calibre of an Oxford (under)graduate in any of the disciplines offered by a university. This may well be true (though highly questionable) in them old Victorian days in subjects like Ancient Gaelic or Medieval Norse but not in the modern era. I thought both Dustylaw and Needmoresleep gave an excellent account in their postings.
I have said it before but at the risk of repeating myself, Oxford, or even Cambridge, do not have the sole monopoly of the brightest and most able individuals under their wings. Let’s take, for example, the most prestigious, most difficult and sought-after, most talked-about in these forums, and most certainly the longest and most expensive course in any university degree – Medicine – the subject that separates the genuine article from the wannabe; the men from the boys. . .
All final year medics in the UK’s 34 medical schools compete against each other on a National basis and on an equally level playing field – the Battle of The Titans, if you like – for post- graduate Foundation jobs in hospital deaneries throughout the nation. Make no mistakes, these are the guys about to be let loose very shortly on your body, both inside and out, (and of your family members’ too) and therefore, have to be the ‘brightest’ and ‘most able’ individuals. In many instances, they really are playing God here – your lives in their hands – and presumably they all come from Oxford , if a certain poster here is to be believed. 
But sorry to burst your bubble. The brightest and most able of this lot come from anywhere but
Oxbridge. This is the latest Table (click to enlarge) i.e. DS’s cohort, to show you where the nation’s brightest and most able medics (the Maximum total FP score – penultimate column) are to be found – in a good half of the entire 34 medical schools throughout the UK, all scoring higher points than Oxford and Cambridge and thus effectively relegating Oxbridge to the second division!
Yes, tell that to your grandmother!
