Most people find an accent charming!I once did the Oxford entry exam for the English language studies and scored a 7.9, so I suppose that might be true. Unfortunately my degrees otherwise don't match University level, so it wasn't enough to be accepted.
But my accent is awful (at least in my mind) and very hard to get rid of as in my day to day life I'm surrounded by Dutch people so I do have a heavy Dutch accent. I lost the Dutch accent when I lived in the UK but that's already 10 years ago now and I am back to sounding Dutch again.
No surprise to me you scored well!
