Red vs Blue Pen in Grading
Here is an interesting story heard in NPR’s All Thing Considered: “Red Ink May Lead To Lower Grades“

Hmm… I use red pen so does that mean I’m more strict? There was a professor who also gave really high grades to students. I even got 99 as my final grade for Applied Mathematics. Wonder what kind of pen did he use to grade?
