One example which really pissed me off when i was a student is how so many math classes in college base a huge portion of your final grade on tons of mind numbing homework. This of course is targeted to the average idiot: the university has figured out that most students have trouble with math and in order to avoid high failing grades they create homework which is a way for people to get points toward their grade by solving the same simple problem over and over and over again. And of course you do not need to understand the material to do the homework, because if there is a problem you cannot do you can just ask the TA, etc. Thus, they replace true understanding with memorisation and dull grinding work. Of course most smart people I knew would more or less blow off the homework and just ace the tests, and thus they would often end up getting a B- even though they probably understood the material better than anyone else.
