Gr 11 chem with Mr Carrington traumatized me but Gr 12 Chem with him was a lot different. His class is slack but he teaches well and encourages you to ask for help. He's willing and understanding. Easy class but youre screwed for final exam haha

Mr.Kozelko is a great teacher!! He is slack, but his tests are VERY easy; his exams are not so tough either as long as you study. Great humor and very helpful! He really knows his chemistry! :D

Had him for bio. Slack, but pretty good if you attend his classes, take notes, pay attention, and do work. There's no such thing as a "deadline" for him. A cool guy for his age. Lots of funny stories.

He's a good teacher... slack but good. He gives you the hardest exams though... BUT if you don't pass his class, you are just not paying attention! He also tells you the funniest things!

Awesome teacher. I'd recommed him for taking bio. He's got the slackness of Mr Dixon, yet you learn like you had Mr Warnick. Really nice and knowledgable guy.
