The best outcome is that the situation is resolved amicably and all parties are happy; the worst is that you will feel uncomfortable taking courses with that professor again and that professor may not appreciate the challenge to his or her teaching and grading.

Is there a time limit to report these? I don't want to waste your time if it doesn't make a difference in my grade." Note the solicitude that you show for your professor's time (and they never have enough of it!). On an essay or short answer exam or paper, always start with something like "I must not understand this as well as I thought I did. But I reviewed it against my notes
