I took calculus with Gluby... he's a smart guy and def knows the material, he just has troubles helping you to understand it. Corny jokes and a class that can get QUITE boring, but he'll soon retire.
He is a smart man. He was only mean to the students who didn't work. When he taught calculus (with a class full of good students) he was always nice.
Doesn't do much to encourage you to work hard. Doesn't take any homework in unless it's an assignment or test. I didn't enjoy his class at all.
I learned more from the bonus problems, should prep you for PDE's more
