> "multiple bites at the apple", so to speak, in terms of grading. It's simply not fair to the rest of the class. Isn't it? If everyone has equal opportunity, how is it unfair if some don't take advantage of that opportunity? I can see a distinction with, say, paid outside tutors, as not everyone can afford to use their services. Rather than unfair, I say that it detracts from one of the (implicit, and not always acknowledged) goals of schools: certification. Teaching clearly benefits from the rapid feedback. Certification, on the other hand, is harmed by the ability to redo, because it also becomes a measurement of diligence and conscientiousness as well as skill. Even so, the consumers of grades (employers and graduate programs) are looking for diligence and conscientiousness, perhaps even more so than demonstrated skill.
