It sounds like a stupid question, but my friends gave me loads of number sof good driving instructors, what exactly do you say to them?
"Hello, can I have you as an instructor?" sounds a bit silly

I just wouldnt know what to say.
Also, i sent off my provisional form on Monday (so 6 days ago), do i need to wait until i get it back before i phone an instructor?
And how long within calling an instructor and having my first lesson will it take? eg. Will they book me within a week, 2 weeks, a day etc....
