All this about GCSE grades and what school you go to does get quite tedious when it is brought up time and time again (especially for oxbridge!)...
I agree there is a substantial amount of luck involved with high-ratio subjects, but regardless of your grades, I really believe the personal statement and reference are crucial to an application; even more so for those universities of which do not interview. Again, it's not how perfect you are but HOW you come across from a teacher's perspective and personally - does the person reading it want to teach you?
I feel like i'm an expert at the application proceedure lol (this year re-application, because I missed my A grade, and wanted a gap year anyway!). Last year I applied to Cam, KCL, UCL, Queen Mary and Warwick: I got offers from KCL, UCL, QM and an interview with Warwick of which I declined.
THIS YEAR i applied to Cam, UCL, York, Warwick and Manchester, and I have offers from UCL, York (withdrew from KCL) whilst anticpating War. and Man.
My grades: GCSE 5A's and 5B's. AS Levels: ABB (B in Eng, Hist. A in Psy) and A'Levels: AAB (A in Hist/Psy and B in Eng, retaken hopefully A) and AEA Dist in English.
Now compared to you brainiacs (lol) my grades are not particularly stunning and my AS's when I applied were not great. But i really feel my PS and Reference got across my attributes, interests and all that - I come from a rubbish comprehensive in a equally rubbish area and to be honest I dislike telling people (and the uni's) that because it had no bearing on my academic record. My school only provided what they could and ONLY ME could do the work for what I wanted.
Sorry to be all auto-bio, but I just wanted to convey my opinion about the admissions procedure and what I think counts. And fasterpurple, please don't SET your heart in stone for Cam, I really believe that re-application English applicants rarely get made offers. Neither me, nor Englishstudent and another person here did not, and also people I know - maybe it's a taboo subject for Cam. But fingers crossed for you all the same!
