I think your grading policy is unfair. I beg your pardon?! Why is a 90% a B? I'm trying to challenge you guys. That's not a challenge, that's a punishment. I've had this policy since I started teaching. It's time for a change. I'm not changing my policy because you don't like it. Put yourself in my shoes. I have been a student once, and I think my policy is fair. I'm going to drop your class! Go ahead! Less for me to grade!
