This type of stuff can happen at any school, as the professor doesn’t typically police the exam room and often doesn’t even show up to the exam…just lets the TA’s handle it, who usually sit outside the room. However, I didn’t think it was that rampant at my school, not necessarily because people didn’t care about grades (they did), but rather because people were worried about loss of face, I’d think. The culture at my school was fairly happy-go-lucky on the surface and nobody wanted to be the person to cause too many waves in public, but it was fairly normal to hear talk about others when they weren’t around.
