I could see throwing a fit, too, depending on how the weighting is handled for partially incorrect answers. If the question is "What shape is the Earth?", if a student answers "A cube", I can see taking off points. However, if they answer "A sphere", do they also lose points? Do they lose just as many points as the person who said sphere or do they get partial credit for being closer to the correct answer of "oblate spheroid"

To put it differently, would I get a better score in OS design than Linus Torvalds? After all, he wrote an operating system that contains bugs, while I wrote no operating system as all.
