My classmates have an average score of 4 and I got 2, which is very surprising. I took few mock exams in class and I was getting 3. There’s one thing that bothers me, which I forgot to label the prompt # for each essay, but I don’t know if AP readers would deduct some points just because of that.
You were usually getting 3 and had an off day.’ it happens. I’m sorry for you as you must be feeling bad, but you don’t have to submit the score. Instead, try to think and see why you scored 3s: study method? Content? application?
