I got done 36 in a 30 and was offered the course in the letter. Just had to confirm I wanted toe course and not the points.
P1ssed off that I got caught at 36 in a country lane speeding up to the national speed limit (camera guy was next to the national limit sign) 
The course was an eye opener.
You think so? I learnt a few things, and made of aware of others. The course made me drive with less haste for about a day...Call me stupid or ignorant. I don't feel a 3 hour lecture will change anyone driving habits.
