My teacher gave back our papers today and I got 87% on one of the breadth papers and 50% on the depth paper. He said that the difference in the grades makes him suspicious that I cheated but the thing is, if I cheated on one of the papers surely I would've cheated in the other?? Needless to say, I was shocked and honestly disgusted as I spent so much time, effort and money (on tutors and books and websites) to get that A grade and he says that I've cheated by looking at the mark scheme for the 2017 papers and that there's no way I could've gone from getting D's and C's to getting a high A/borderline A*
What should I do? It's quite awkward as he still thinks I've cheated but I'm determined to show him that I didn't cheat by doing well in A2 but there's a lot of tension right now.
I'm just upset that he didn't even think that I worked hard and got that grade because I'm usually an underperforming student :/
