My Professor changed my multiple choice answers. What should I do? My prof changed some of my multiple choice answers on a test to give me a better grade. I noticed because I remember putting different answers for the questions and the way they were circled was not like how I write. I would have passed the test anyway, so I am not sure why they would have done this. I feel guilty because I want my grades to be based on my own merits. But this test was not a case where the prof raises a student mark because they deserved it based on effort. They deliberately changed my incorrect answers to give me a better mark on a test that I already did okay on. What should I do if anything?
This is really tough to approach. On the one hand, it’s incredibly hard to prove this (also since there’s no clear incentive for the professor to do this). On the other hand, you stand to lose a lot if you’re wrong.

That said, paraphrasing Hanlon’s Razor: Never attribute to malice that which is adequately explained by incompetence. 

Your professor might have mixed up something, or accidentally erased your answers (and then wanted to err on your side). You can simply approach them and nicely ask about question 17, that you distinctly remember putting another answer, but you could be wrong etc.
