Mr. Callender was my all-time favorite teacher during my high school years. Although I wish he'd do a better job clarifying chemistry concepts, he's a cool, helpful guy in general and goes above and beyond to be the awesome, funny person he is. 9/10
Mr Callender is an awesome teacher! Thats really all that I can say, he's fun, he's helpful, and he is just all around cool.
Excellent teacher when hes actually there. Has a meeting or something at least once a week. Prepare to learn by yourself.
when you're absent 40 days out of the year, you shouldn't be a teacher.
He's halarious and helpful. He makes Chemistry FUN! :)
I hated the actual class. But Mr. Callender was one of the best teachers I have ever had. He made chemistry exciting. Awesome experiments too.
very silly but in a great way. you make learning chemistry fun
He is an amazing teacher. Chemistry was never my thing though. He is a hard teacher but he teaches material well and he is so funny. woot.
You are a realy annoying person, and what are you like 12? I mean your class is extreamly easy and is mostly a blow off but you act WAY to childish. Grow Up.
