I requested I did a speed awareness course online a couple of years ago, when I got busted for doing 73 in a 60 zone. The benifit of doing an online course is you can book anywhere in the country. I booked a course with Durham council, as it was the cheapest £74 compered to £95 for my local provider. The benifit of doing an online course is the boredom time is halfed, than it would be attending a face to face type course (yes done those to) though I believe the face to face course’s is now the same times depending who you book with.
