its luck. well, as long as your a decent driver you'll be ok but tbh i failed twice, first time for speeding- oops! but only 43mph in a 40 and another instructor couldve decided it was minor. Second time i over took a lorry then found no room at the other side to tuck in because a queue of cars right up to it, so fair enough i was stuck in the middle of the road-serious fault.
Then today i passed, my driving wasnt great but only got 2 minors. I stalled, touched the kerb (only lightly), went through a pot hole, all things which if he really wanted to he could have failed me on..
