Hey Jo
YOU session is pretty basic. If you can do alright at school you should be fine. It's like an IQ test eg. They give you a word, you pick A,B,C or D depending on which one is similar or the opposite etc. Basic maths like X buys 6 lollies at 25c each, gives Y amount, how much change. The hardest maths on there wasn't too taxing (think it was pythagoras theorem), they're not trying to see if you can only get the hard ones right, so just plug away at them all, skip and come back to any if you need to. The guide they give you is pretty spot on, and I didn't have any table/graph questions from memory.
