Did one when I was 18, got caught doing 36 in a 30 so was legible for it and of course I hadn't had my license long. Was 3/4 hours of classroom stuff which to be honest I quite enjoyed, I used was as an example of a boy racer as most of the others in the room were 40+. Best part of it was when I left the car park after and followed out a woman in her Range Rover who was sat next me during the class, she clearly didn't give a shit at all as within 10 seconds of leaving the car park so overtook a slow car on a pedestrian crossing and left me in her smoke, I had to laugh
