Hi Boxerman,
Please have a good read at this forum for loads of information on Stage 1 (and the later stages too). You should have already been sent information by NATS to help you prepare and things that should answer your questions!
Anything specific, please ask, but to save us all repeating the same things over and over, learn *everything* NATS has sent you and read the whole of this forum to be as prepared as possible (I know it takes a long time - p22 has a good post there to start with).
Good luck with Stage 1!
