Talk to the professor and see if you can take it early. As long as you have proof of the death they should be understanding, if not go above there head to the dean. I'm sorry for your loss.

that's illegal for him to do that.

I'm sure your professor was just exaggerating. Explain the situation, I'm sure he'll understand

That's definitely not allowed, if you have proof of death. Go to your registrar's office if necessary.

There's loads of good advice here which hopefully will get you out of this situation, but if it comes down to it - fail. It's not the end of the world. You can resit the exam or retake the class, or take something else. It won't make any difference in five years time, but missing your grandma's funeral will.

Sorry for your loss. Show the prof the obit. Tell him that you can take the test early or late, his choice, but that you are going to the funeral and will honor your grandmother's memory properly. Let him know that you decided that your attending is not optional. Do everything via email, so it's ALL in writing. If he refuses, then you tell him that you are going over his head to the Dean. And that your grandmother's lessons outweigh anything he could ever teach you. May you find peace. ✌

Do you think it was an inside job?

fortunately, colleges have checks and balances in situations like this. You can petition the Dean to retake the final due to death circumstances, and they will likely allow you to do the test. To start though, I would suggest talking to your professor. show him proof of the death and that might change his mind.

If he does not apologize for his stupid choice of words and make an exception for you, then go over his head, you will get a rewrite.

sue the professor, not the school
