This man is one of the greatest teachers known to the face of this earth. I have never had a better math teacher. I only wish that he would stop cursing.
he thinks hes so funny and lectures more about himself and is not very willing to help
Mr. Hartman was the most influential teacher of my high school career. He is the kindest, most caring, and most hilarious teacher I know.
I think Mr. Hartman is an amazing teacher. He is hilarious and really cares about his students.
HIS HOBBIES INCLUDE CHAINSAWS AND FINGERS. AND HE HAS THE HEART OF A BEAUTIFUL CHILD. IN A JAR IN HIS DESK. BUT HE'S A GOOD TEACHER.
brillant teacher.. accelerated math is very difficult
Hartman Better than my College TA at explaining local linear approximations
