#### Abstract

A common grading practice among educators has been to drop low test, quiz, or homework scores to help students in their classes. Although there exist simple cases in which it is easy to determine which scores should be kept and which scores should be dropped, there are many more complex cases that require an algorithm to solve. I will be discussing different ideas for how to easily determine the best set of scores to keep, why some methods don’t work, and will go into detail about an efficient algorithm.
