Your all kind of missing the point here I believe. If your son was the one with a 92% who only gets a B, and therefore he doesn't get the scholarship money because his grade point average is only 3.0 instead of 3.5 or 4.0. Now it comes out of your pocket while the kid three blocks away graduated with 92% and all A's. He gets a free ride and his parents spend that money on a lake house or something. The point is its not right. Schools or Scholarship Foundations don't ask O what was the Grading scale. They ask what was your GPA. I can guarantee this bites someone on here in the ass and then you'll sing a different tune. A Diploma is a Diploma no matter where you get it therefore the qualifications to get it should be uniform.
