I have a theory on the general University admissions process: it's mostly random. I mean, can you seriously imagine the admissions officers looking at every single application they get, wheighing up the grades in each one with others and then offering places.
I'd imagine it works like this: they receive an application; skim over the personal statement; glance at the grades - so long as there's a minimal amount of a few As at GCSE and A Level you're entered into the decision process - then through some completely irrelevant factor it's decided.
What I'm trying to say here is that it doesn't really matter a whole lot even if you're an 'outstanding' candidate; there's still a lot of luck involved. I've seen lots of people get rejected who had loads of As and A*s, and quite a few who've gotten in on some pretty average grades (for Durham anyway), myself included. I had 1 A* for GCSE, 4 As, 4 Bs and a C. And 3 As and a B for A Level, but here I am.
Meh, perhaps it's unfair, but that's life. Get over it.
