Is 10 hours of driving lessons enough?Watch
Average for most people is 40 hours.
Are you doing any practice outwith lessons? If not then I doubt its enough
Unless you're exceptionally good, no. Most people say the average is 40, however my instructor said 20-24 should be enough. I passed with around 24. Any less and i wouldn't have been ready at all.
If you can stay with the same instructor as when you pass if they still do the passplus course the instructor might just sign you off on it for less than what it would cost you to actually do as the instructor knows your driving competance and know that it would be a waste of time to teach you to a level and understanding that you already are.
