Harvie's all gud. He is helpful 2 you just got 2 listen.
Get off it you complaining guys, the reason you think he is so unhelpful is 'cause no one ever does work when there are relivers duh! Mr Harvie is cool, he is always nice and talks to you like you are equal to him not like the other teachers, and ofcorse he can't hear very well he is growing older! give him a break!
I find him to be very helpful in maths. He is a very knowledgable man, and you can learn a lot if you just listen.
Basicly, learn to be more helpful, and people will treat you better
