Academic Achievement

It bothers me that "C" is average. It's considered "normal" to be 25% wrong! Now, I'm not going to get started on the fact that there is a huge problem with grades and testing in the first place, but I digress; the C average. RAGE! Seething, blazing hot rage! The biggest problem with setting the standard at 75% right is that it's teaching kids to both not expect to do well and to not try to improve. By saying that you're doing fine in a class when you're missing a fourth of the questions is like saying you're doing fine when your arm just got chopped off! But I want to say that setting the standard at 90-100% is also destructive. It means that if a student (around 10 or so) gets 1 question wrong on a five question quiz, they would emotionally tear themselves asunder for it. And image how bad it would be in High School, when parents are stressing good grades, the work has transformed from a rivulet to rapids, and the other components of high school life are dragged into the equation. I do believe that a C should still be a passing grade the same way that a D is a failing (that being the intermediate grade that is merely a transition to either a C or an F). So reader, tell me what you think: is the standard to high? Or is it to low?
