For those of you who can't be bothered clicking the link, here's the Chinese pre-entry test: Seems like a Year 11-12 Maths 3-Specalist (16-18 year olds) in Australia... Not super hard, thing is others are better at it then others. These take some skill but mainly rely on luck and the ability to see the different geometic relationships within the shape. Personally never liked it myself, I wasn't one of those 'Gifted Ones' And here's the English University first-year test: Year 9-10 in Australia (14-15 year olds) , although might appear in very easy Year 12 maths, (maths apps).
