I've just finished my A-Levels for University, and I applied to read Law at Trinity College, Oxford.
Do not set your hopes to high; because the bigger they are the harder they fall. I was educated through the state system, achieved 6 A*'s & 6 A's at GCSE, I achieved 4 A's and a B at AS-Level, I am predicted 3 A's at A-Level and I also have A distiction in an Advanced Extention Award and the first A* in an Extended Project Qual new for 2009. My perosnal statement was personally endorsed by my principle, only one of few students had that honour.
I was rejected from Oxford, without even an interview. Although, convinently two students from my college you used to attend a Grammar School to complete their G.C.S.E's, the only two people in the college, managed to get a place. Oxford, despite what they tell you, is biased against state application, although it did't help my application by applying to Trinity although they should have pooled the application.
I'm not saying don't apply, just do not expect to much and if your from the state sector choose a college lower down on the Norrington Table. I've now got a place at the University of Leicester, the 6th best law school in this country mainly because of the oppertunity to study European Law in Malta in my third year; just because it's not Oxbridge, does not detract from the value. Look at the oppertunites, Oxbridge cannot provide you with the same social experiances.
It's just a shame that law sets look at who you know, as oppose to what you know. But I just want to be a humble administrative legal barrister, so a good law degree from a top 10 university will suffice.
Good Luck Thou!
