What happens if I do well in my other two subjects but fail one? i got an E due to horrendous circumstances that happened a few days before the exam, my predictions are high and my teachers know I can get better grades when I do my A2 because in my mocks i got As and i worked very hard, but i'm terrified of the thought of having an E on my uni application, especially when I want to go to Durham which requires 3 As. My other grades were As, it's just this one paper.
