Different exam boards have different dates
Were you doing the exam where there's A, B and C questions, and the C one's something like describe the Christian view, opposing view and your own view? When I did it last year there was a big range in grades that people got, but I think most people got Cs in it, including me, after two years of doing the stupid practice papers I got my worse grade in the exam
But if other people did badly, it's better for yourself because hopefully they'll lower the grade boundaries.
