Lone eagle I urgently think I need to clarify your post because before people start worrying lots and lots, oh no I didn't do one of the 5 subjects u listed.
A CORE subjected is basically subjects that Universities will accept for UCAS points.
Lone eagle placed French as a core subject, if u did German etc don't worry a Language is a CORE subject.
As is Politics, Computer Science, Economics, Sociology, Anthropology etc etc list goes on and on.
Lets not panic people please. I am 99% confident that BA will accept any subject except General Studies (similiar to the majority of Universities in this country).
