Heylo,
I am a maths geek so I will provide details of the test (currently in year 9, did the exam last June).
SKGUN11 had said that the Mathemagics test was mostly year 9 level and the last couple were year 10 questions. This is correct and the test does indeed contain questions that students may not have encountered before.
The test consist of these problems (I cannot remember all and will provide details only of the ones I remember)-
-Algebra- solving equations- theres a couple requiring you to solve algebraic fractions.
-Pythagoras- They may give you a rectangle and ask you to find the distance between a bottom edge to a top edge diagonal. Sorry but since theres like no picture and stuff I can't explain it that well. Therefore, you need the height of the rectangle and know the distance between the bottom edge to the bottom edge diagonal to it.
-Trigonometry- like one or two question- does not require to solve as we are not allowed calculators. All we had to do was to use the trig ratios. Eg. A) sin theta= 4/5 B) cos theta= 4/5.... and so on.
-Bearings
-Geometry
-Quadratics and linear graphs- Quadratics it may require knowledge on factorising, expanding and simplifying. Also, there was one or two graphs which required finding the midpoint of the quadratic.
-Surds- maybe a couple of expand and simplify- Eg. (2root3 -5)(5root 10-1). There may also be just simplify- Eg. root 50 would become 5 root 2
There are some other questions that require understanding of BODMAS, percentages and ratios.
There may also be questions that may be from year 8.
Also, here's a link to practise exams so you can have a general idea of what stuff will be on the test.
http://www.education.vic.gov.au/school/parents/secondary/pages/practicetests.aspxI'm not sure what level the practise exams are, but they seem slightly easier so I would assume those practise test would be to prepare year 8 taking the test for year 9. Although it may be true, this is still very good reference to prepare.
