Awesome guy. Not the best teacher, but not super bad.
his class is really hard.. but i think he teaches enough & even if hes strict he can be understanding. he is very funny! you have to study a lot though.
i hated him in high school, but i love him for getting me ready for college.
great teacher over all. the notes can be a pain sumtimes but without them i would get an F-BOMB on my tests.
having costello for chem is the worst. goes off on tangents, tells us things"we dont need to know" before the things we do. never available for help. distracted
i love all the extra credit assignments...good guy...means well
TOOOOOO MANY NOTES, over all he is a good teacher. makes a batter hands on teacher then a class room teacher.
he a cool teacher, however, its sometimes hard to understand what hes trying to teach you.
He lacks the ability to keep the lesson plan concise, way to much unnecessary work losing the average student in a mess of unfinished work, not recommended!
Odd teacher. . .ok at teaching, but sometimes seems distracted and it makes him teach worse. Otherwise, he is ok.
i love this class!! I fraeking hate science too! makes me want to be a marine biologist. Great speaker, really clear, and awesome teacher.
his notes are concise and easy to understand, but there are a Lot. and his tests are reaLLy hard. he's really into marine science
nice guy and all, but not the best teacher... vague at times and has a hard times explaining things.
hahah hes an a-okay teacher i guess. but hes really funny and extremely random. and yes, a better friend rather than a teacher. LOL. talks too much sometimes though. and owns cool hamsters!
