McMaths online is a take-away worth getting.

Maths Online is a high quality, independent online maths tutoring program based on Australian state curricula for Years 7 - 12.

Maths Online was developed by experienced Australian teachers. The program features hundreds of fully animated and narrated maths lessons with over 15,000 exam-style questions to test a student’s mastery of maths.

Maths Online is provided free of charge to every secondary school student in Australia through sponsorship from The Golden Arches but is a real worthwhile cause when you take a look at the site and what it offers for nothing.  It is a great resource for high school kids who either want to push themselves a little harder or those that need some extra assistance and cant access a tutor.  Access it here.
