Oxford with okay GCSEs.Watch
Agreed. I know a couple of people who applied with similar or slightly higher and got rejected pre-interview - it's not that they can prove you wouldn't necessarily give a good interview, more that the competition is so so high for law that they have to select somehow to even start interviewing
I had to tell them that this is an excellent start, but they also need to ace the LNAT and the interview, which will be no walk in the park, believe me. I also believe that a lot comes down to natural talent and being great at logic.
I am really sorry, but I don't think you would stand much of a chance if you applied, but obviously it is up to you. Even if you did get A*A A for A level (which is a massive jump) , you would still need to negotiate all the other hurdles.
