Nicest man ever. Really funny! Makes Calculus easy. If you don`t understand something always explains it to you. Too bad he retired because he was the best math teacher at Coffman
I"ve never been good at math, even when I worked at it, but Mr. O'Connor makes calculus easy. It's not the class that is easy but the way he takes the time. Very fun and funny. He is purely awesome
Awesome, prepares you for college. Do the homework! Very fair and wants to help you out.. if only my college teacher was as good as him..
Amazingly awesome teacher. He's the funniest and most easy going guy you'll ever meet. Extremely helpful and clear in his teaching. He's nice and he makes AP calc easy and fun!
The best math teacher I've ever had. I usually dread going to math, but this was definitely one of my favorite classes in high school.
One of the best teachers i've ever had. So incredibly funny and teaches the material very well. I use the notes i took in his class in college today.
The FUNNIEST and NICEST teacher ever!!! I understand his teaching too!
O'Connor Rox!! I love the Wlter Fish story and the executions. I became an engineer because of his AP calc. class. He really prepares you for the real world in math.
Had him in '90. Hated math then and still do, but his class is the only math class I ever enjoyed going to! Excellent teacher! Glad to know he is still going
Love this guy! I hate math, and I still look forward to his class!
He made math fun an easy to understand. Ten years late, I still remember the markers:)
