This comment doesn't really add anything to the discussion especially because colleges have different grading scales and culture of grade inflation or deflation. For example in mine most GPAs hovered around 3.5. A 3.8 would be rare.

I haven't heard of any universities recently where the problem is instead grade deflation, any links to share?
I only witnessed cheating twice; Chinese and Indians. In general though, the Asians worked their asses off; 1st generation immigrants "off the boat". Very tough competition.
