skychick2003,
the maths is really nothing to get worked up about. you will need to know how to do a few simple distance, speed, time calculations. 'You drive 10 miles to work every day. the speed limit is 60 mph. On one particular day, the speed limit is reduced to 40mph. How long does it take to get there?'
If you can do that sort of thing you are laughing. Also it might be worth practicing a few currency conversions. not rocket science, but certainly designed to separate the wheat from the chaff. there are millions of web sites and books available to give you a bit of practice, so if you are serious, then a little bit of work and you will be fine.
Good luck.
