Bursting My Bubble

I had my final cumulative exam on Thursday at work. The exam took me four hours to take and I am a fast test taker. I was glad to be done with it, though. My trainer finished grading it Thursday night and my score was a 98. I needed an 80 to pass. She said that she's never seen a better score on the final. I was pretty excited because of my grade and because I was done with the tests. Last night my trainer looked at my exam again and apparently she forgot to add in a missed question. My grade is actually a 96. Which is still high and completely respectable but just not the same as getting a 98. Does that mean I have to go back and tell people that I really didn't get a 98, I actually got a 96?
