I'd go for Oxford rather than Cambridge if I still went for English.
I'd explore different degrees a lot more as I'm still uncertain I made the right choice. In year 11 I was going for law, psychology in year 12, and then the month before I applied I decided on English. Perhaps I'd look harder for a psychology course that has less focus on science, as I don't find it too easy to get to grips with biopsychology and research methods. Maybe I'd look into degrees such as sociology and anthropology. I honestly just don't know.
Wouldn't change the universities I got offers from (Durham, Lancaster, Manchester and Nottingham) as I was very happy with them. I would, however, change my college preference at Durham as the circumstances since that decision have changed.
