Costie is great! He may not be the most modern teacher but if you really listen, he's awesome!
Costie is an amaz teacher. You do NOTHING ever. you get a good mark and attendance is never taken. You're basically all set wether you go to class or not.
everyone shut up... you can't complain about costie, hes the best teacher on earth, sucha joker, dosn't care not picky.. get a life everyone.. im so blessed to be his student.
Ceribus Perabus. Supply and Demand. Those are the only words you'll learn in his class. Coolest guy ever, but worst teacher. Do work - get a decent grade
So far, in all my time going to school, Mr. Costie is the best teacher I've ever had. Forget students, it's teachers that should be taking lessons from him.
very nice, likes to joke around, tells lame n pointless stories
not that great of a teacher, but a fun teacher--you will spend more time playingames than workin
Costie will forever be what Assumption is all about. Cross-Canada and Kong stories are worth the price of admission.
