A week prior to my final I calculated my grades and knew I needed an 80 on the final to pass the class. I met with my instructor to review the previous quiz. It was a test question that she said she would throw out because it could have been two answers. I didn't think about it any further until after I made a 79 on the final which made me fail the class. I needed a 79.5 to pass the class and I had a 79.4
I emailed my instructor. Asking about the test question she said she would throw out because if she threw out that one question then I would pass. She emailed me back and said "Sorry all test are final and grades can not be changed. I misspoke during test review regarding throwing out that question."
Is that fair that she can tell me one thing and then go back on her word? Especially when that one question will pass or fail me? What would you do in this situation?
