I'm not saying that Oxford students don't work hard, but so do other people.
Apparently we can actually request the statistics of where the research council awards go to, I recently came across such statistics, not for the AHRC but for another research council. There were 27 graduates from Oxford, 7 from Cambridge (second highest) and all the rest where 1-2 people from other unis.
Just because your application (or mine, at least for last year..) is different to the norm, it doesn't mean that the norm does not still exist.
I also think that, despite your claims, you seem to think that somehow, having done your undergrad at oxford, you are special...having survived it and all that. In my opinion, the only advantage oxford people have is that they know the system and what Oxford wants. And believe me, what Oxford wants is very specific, and just because that's what they want it doesn't mean that people who think differently are not good. I've seen people who came first at Ivy league unis and are here with scholarships getting marks below pass. This in my opinion does not reflect on the quality of the student, just on the fact that Oxford expects a specific "way of thinking", which naturally people from Oxford have had years to practice on.
