I am well aware some of you loathe the 54321, but it is here to stay. Looking back over everyone's grades, across all classes, there was a lovely trend...
Students who consistently turned in 54321's and scored a 15/15 recieved higher final grades than their peers who did a poor job or neglected to turn in the assignment. Sure you could argue: the people who turn in assignments will obviously have higher grades than those who do not, and doing the 54321 doesn't help you learn anything. However I'm going to argue that people who do the 54321 are regularly reviewing the material and therefore are able to better study when it's time for a quiz or test. There you have it.
