I'm assuming you mean UK license ......
My Scottish husband has only just recently passed his drivers test as he never really felt the need to drive before. He went through BSM and they have books to buy that really prepare you well if you're willing to take the time.
You can also buy a cd-rom from them that gives you a mock theory tests so you won't be so nervous and find out what you need brushing up on. There is also one for the hazard perception test too (boy, do I do terrible on that!).
It'll be my turn in the new year and I am definitely not looking forward to it after 15+ years US driving and 3 years UK taxi rides.
