"A" The Hard Way, 2010: GradeInflation.com's Sweet Sixteen of Tough Graders:

 
March Madness is upon us. Last year at this time, GradeInflation.com came up with a Sweet Sixteen of grade inflaters. As the graph above shows, grade inflation is pervasive in academia. It's present at almost every school that's part of a major athletic conference.

We could have made a new Sweet Sixteen of inflaters this year. …  We thought it would be much better to look at the other end of the spectrum: the schools that defy the trend of the easy A. These are rare schools, but if you look long and hard, you can find them.
