There was a time when a C meant average. The average GPA at four-year colleges and universities has risen from 2.52 in the 1950s to 3.11 in 2006. And according to Stuart Rojstaczer, a former Duke University professor and founder of GradeInflation.com, GPAs only keep rising. At some colleges, Rojstaczer says, over 50% of the grades given are A's.

In fear of diseases (like cholera and trench foot) and of course, the constant fear of enemy attack.orld War 1 trench warfare was so intense that 10% of all the soliders who fought were killed. Thatâs more than double the percentage of fighting soldiers who were killed in the Second World War (4.5%).
