maybe you can try my tutor?
his name's lloyd (Dr. G)
lives in mill park (north-eastern suburb)
he charges 40 dollars for one and a half hours but if you do spesh with him he'll do it for 30 dollars a subject. the lessons aren't one on one but he'll happily stay after the lesson if you need a little one-on-one.
I know he has some pretty amazing qualifications regarding maths but i cannot quote those off the top of my head
but i will tell you that he's the head of math at melbourne high, person who writes their sacs and has a place on board that is developing the new national curriculum. he's definitely helped me: i'm currently averaging 92-ish in methods and 95 in spesh is sacs so hopefully he can help you too.
this is his home number: 9436 1104 hopefully he has places for your sake
