Ha, you rules followers! I mock you and your faith in being enfranchised in an equitable system.
I had a college friend who got very very irate with me any time I got an extension on a paper.
She extrapolated that grades were competitive and translated into job opportunities. Which I don't think is true - we both graduated from Kenyon with a B.A. and that's all anybody would really look at. But I didn't care - I was only interested in writing the best paper and sometimes that took more time.

This.
Although, I'm very much "I did the crime, I'll do the time." I never negotiated for a grade, because if I didn't get an A I already knew that I either didn't grok the subject or hadn't spent any time on it.
See also: This weekend. I got pulled over for speeding (no ticket). Some hours later, when my Lawful Good DH was speaking to me again, I mentioned that the "Reduced Speed Zone" was about 20 miles before the speedtrap. He agreed, and said he was thinking about mentioning that to the officer, and wondered why I hadn't. I said, well, either way, I was speeding.
I don't see a problem with negotiating where grades are concerned if you can back it up with something reasonable. I've had teachers glad that students cared enough to try and make their point and sometimes learned more from it.
However, I do have a problem with the kind of thing that happened at my high school, where it was widely considered that both the valedictorian and saluditorian were chosen because they had the pushiest parents. Both of their mothers were well known for petitioning teachers for grades and extra time for tests. One of the families was very infulential in the area because the father was the president of a professional sports team. And yet the kid who also got a perfect GPA and a 1600 on his SATs and took a harder course load had parents who were imigrants and had never been seen at the school didn't get anything.
