Jessica's parent tagged me: "My daughter's exam was graded incorrectly, missing 30 points. We demand a regrade!" The test was for a Tsinghua admission spot. I caught Jessica Carter cheating. She begged, so I only deducted points gained from cheating. I replied: "Jessica Carter's score is correct." Jessica's parent retorted: "With 30 points, Jessica could get the Tsinghua spot! If you don't regrade, I'll complain to the Education Bureau for shady dealings to give the spot!"
