If class rank is based on unweighted GPA, it doesn’t reward people for taking challenging classes. If class rank is based on weighted GPA, it tends to penalize people who took a lot of art and music classes (or other classes that aren’t designated “honors” for whatever reason). I think there should be some kind of class ranking system so people can say they were in the top 10% or whatever, but ranking people in a list can make them unnecessarily risk-averse when they’re choosing classes.
