Hi Oldskool, Thanks for the type 6 "cheats". Don't you just love multiple choice? So many questions can be answered more easily using this process of elimination and saving heaps of time. My DS is stuck on doing things "properly" and I'm showing him these ways of making life easier but he's more prepared to accept the advice if it comes from anywhere other than me!
I still remember 30 odd years ago I was given similar advice on exam technique from our fantastic Maths teacher. Something he always used to say and which stuck was that "lazy people make the best mathematicians because they always look for the easiest way to solve the problem"
