Professor Rejecting Doctors Note

So last Friday I woke up quite ill. I had a high fever and vomited several times. I had a quiz that morning in my intro to business class. Its worth 10 percent of the grade. I emailed my professor and told he told me i would need a doctor’s note to be able to makeup the quiz. I ended up going to the doctor on Saturday (the next day) and got a note. They gave me an IV and such and i went home feeling improved. Anyhow on Monday or today when I handed the docotr’s note he said wont accept it as the note was for Saturday which is the day I went to the doctor. So as of right now im getting a zero on a quiz that there is no possible way I could have taken. This seems super unfair if you ask me. Is there any thing I can do?

Did you call the doctor on Friday? Was Saturday the first available appointment? If that is the case see if you can get a note from the doctor’s office describing this sequence of events.
