Schools are too easy as is. Problem is parents think that subpar work deserves a b or an a when in reality shitty work deserves a shitty grade.
Far too many parents get into a hissy when their kids come home with bad grades on a relatively easy assignment and then complain that the material is too hard.
If you took the average american high school kid and placed him into school in say, india or china, they would flunk out pretty fast. We really ought to be demanding more of kids and up the standards. Your going to have to learn alot of that material at some point anyway.
When I attended my daughter's middle school graduation last year, I was proud to see that she had an asterix by her name indicating that she had attained the honor roll (GPA of 3.5 or more) for each of the nine trimesters of her middle school career. Until I looked over the entire program and saw that 55% of the class had the same asterix! Talk about blatant grade inflation.
