Gimme my A or I will speed dial you to death!

Well, I haven't quite had these experiences with students wanting As in my courses, but I have had the odd experience of undergraduates retaking our required history and philosophy of education class, some more than twice, to raise their GPA in order to remain in the teacher ed program. Students retaking a class to get a better grade? I had never heard of it prior to coming to this Moo U. And, in the summer especially, I get the students who need to get an A in the retake in order to salvage their GPA. I ask, do I appear a fool? Surely these students know it is not only MY COURSE and MY GRADE that is responsible for their lower than needed GPA! Sheesh.
