Tip: KNOW YOUR CONVERSIONS !
If you need to, sit down and learn them (lbs, kg's, mph, kph, litres, gallons etc etc). There's bwgger all point being great at the arithmetic side if you get to the end of the question and it says "Answer in pounds/kgs/mph etc if you please". The number of times you can hear the word "F..k" at around the same time, quite amusing.
