He talked about his grade with her several times after getting his midterm progress report, and in my opinion she was unprofessional (told him several times she was too tired after class to talk to him), seems to have been punitive (significantly changed how she started marking his work when he started asking her to input his completed but not graded assignments), didn't follow through (ultimately never input some of his assignments) and didn't keep her word (she told him his last assignment would earn him full credit, then marked it as 80% which meant his final "B" grade missed getting an "A" by less than 0.5%).
