Mr. Koellner is the best! I love his corny jokes. He is always willing to help and go over things if you don't understand. His class is still one of my favorites!
I hated this class. I didnt understand anything! Good luck!
"NO!" - Koellner... you get used to him shouting that, but he's a nice guy and the class isn't horrible
He's an alright teacher but the class is soooo boring.
People think he's boring, but i think that he is a great teacher!!!
