Students in one New Jersey school district may have to hit the books a little harder to get a passing grade. In Mount Olive, you won't see any more Ds on report card starting this fall, only A, B, C and F.

"I'm tired of kids coming to school and not learning and getting credit for it," said Superintendent Larrie Reynolds in a Daily Record report.

This approach worked well in Kentucky, which got rid of the C grade as well. "In today's world, you've either got it, or you don't", Kentucky principal Steve Frommeyer said. "Theres no opportunity to just be OK".
