thank you.
I realise that this isn't the only thing I need to concentrate on. I currently have a world map with lots of little pins in it stuck to my wall and my floor is strewn with newspapers, magazines, mathematics books, problem solving exercises, homemade flashcards, etc.
It may sound a little geeky, but I'm actually enjoying it. It's making me look forward to my OASC attempt, whereas a year ago I was terrifed at the prospect!
Thanks AMiller, much appreciated!
