He is a really knowledgeable and knows a lot about Geo. he's taught me a lot and is the best ever. Don't get on his bad side.
dont get on his bad side, good at teaching but sometimes you just hate him so much. but inside hes a good man. :) teaching- above average.
good teacher is very helpfull and cares about his students unless you get on his bad side then he crushes them. (tryed to crush troy)
doesnt know what he's talking about makes alot up not good.
He is a nice teacher and he has help the year 13 when we were at camp
Haven't had him as a teacher but as a part time camp leader he was awsome!
Mr callanhan is a good teacher but is very tough , which is good and bad.
Dont be judge mental of this guy. Yeah he may look all big and scary but hes cool! And not just as a teacher in school but for sports also. Hes really easy to get along with and understands you well.
hated him at first but i got used to him and he was an ok teacher
Callatron is the man!! Do not tell him i said that though!! He is a very talented teacher and will give you the respect you deserve hence why he gets on well with the seniors!!
Really good teacher, tough but for your own good. definitly nicer to the older students
Mr Callachan is an absolutely awesome geography teacher, only wish I had him again this year. I would be amazed if any of his students fail in the coming exams. He likes to mock people though ...
Mr Callachan is the only teacher that can control my class and his is the only lesson that I learn anything
Mr. Callachan is a very good teacher with a sharp sense of humor and has an extrodinary ability to get students to pass their exams with merit and excellence.
callachan, where do i start, he may be a good teacher and knows his stuff, but he is very harsh on students, particularily one in year 13, he will get his revenge one day, one day , so watch out!!
Mr callachan is off the hizzle! broooo he is the best teacher and is an awesome house leader too :)
