A: I was looking at my test score and think that it should be higher. B: Is the math wrong or the way the answer was marked? A: I think an answer got marked wrong that should have been marked right. B: These things can happen; let's double-check the answers first to be sure, all right? A: That would be great! B: Look at the answer sheet and compare it to your answers. Do you see any place where I made a mistake in grading? A: This one right here should be right. B: Yeah, I see the same thing; now we can do the math and check that, right? A: Yeah, let's do the math. B: I count all of the correct answers, total them, and divide by the total. Does this look right to you? A: Looks pretty good. B: Thank you for caring enough to check on your scores; keep studying!
