His class was really slack. It was fun and it felt really nice to be in there. He's very patient and helpful too
Mr. Kozelko made sure that I did my best, by explaining questions I had , and being patient. He loves to teach, you can tell... He is the best teacher I ever had.
Funny teacher and he is the besthghsgdhsghdtysfdgsdfgdfgdfgdfffffffffffffffffffffffffffffffffffffffffffffffff
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.
One of the Best teacher ever. Extremely niice and very very helpful, will go out of his way to help you
I loved his class! Great notes, gives time to work, and is very helpful. He's funny too!
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!
Probably one of the best teacher. I really get his class hes extremely talented when it comes to teaching and always has cool stories.
very fun classes, but he gives hard tests.. he made my class make ice cream from scratch during our last class.. that was fun and yummy =)
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.
Funny, easy to talk to, very clear, and lets you ask questions. Without a doubt one of the best teachers at Sisler!
Can never go wrong with him! Never mad and never fail to entertain! Has excellent teaching skills! The perfect teacher all in one! A++++

one of the best teachers at sisler....he isn't super strict but at the same time we all learn a lot and he's really helpful. AND he tells the best random stories :)
awesome teacher very understanding and has cool theories and random, but very interesting facts about everything helps out a lot and is available for help a lot when examtime comes
