Cos is an awesome teacher. Sure, at first yearbook was a little rough, but it got better! He took it in the right direction. He is also a great person. Definitely one of my favorites.
Dont like him at all...does not know what he wants during the yearbook class.
mr. costello is so funny he's a really great teacher and not too hard!
Mr. Costello Rocks!! He's so cool,and he cares about every student!
Costello is an awesome English teacher, he actually cares about students and teacher understanding not fact memorization.
Very cool and understands that you have a life besides just school work
He's the best eh. He is also know for his famous football play, "the slow end around" I think he is the best english teacher on the planet.
Cos is AWESOME!! Good teaching style, knows his stuff and loves what he does!
He's fun, insightful, and knows and loves what he teaches
