Best teacher! he taught me the best study technique in the world and made science interesting and engaging!!
This man is the biggest champion ever. I would love to see an awesome-off between him and Mr Fryirs (p.s. He's a good teacher too)
Mr Gahan is excellent. Best teacher in the Science faculty, makes it interesting with extra information, I did so much better in Year 11 compared with year 12 when we switched teachers.
He is an excellent teacher, and in my opinion more should be like him.
Mr Gahan is FANTASTICALLY BRILLIANT! I love his classes, as he makes everything sound so interesting (even Biology, and thats confusing, I don't get it) He also gets along with all the students!
Love ihm. Hes a great teacher. He lied to my class last year and said we could have a party in his kombi when exams were over...never happened.
Awesome, especially on cross country day when he had the beach chair.
