Okay a couple of Q's -
1) Is there a minimum number of hours you must have been driving for before you can legally take the practical test?

2) Can you book your theory test before you turn 17?

you can take your theory before your 17. If not (which i'm sure you can) you should be able to book it.

you don't have to have any lessons before you take a test, you'll probably just fail.

I was thinking of Scooter theory, I think you will need your provsional before you take a theory test. So you'll need to have it and be 17 I think.
