Mt friend (really, my friend) went on this course a few months ago, she said it was very informative, you don't do any driving!.......didn't do her a lot of good though, she got caught again a month later!.......36 mph through a 30 mph limit, and then again 2 weeks later 34 through a 30!............6 points in just a few weeks!........
Son has to go on one shortly. Doing 35 in a 30mph zone. I think he is the last one in his company to be going on one. Better than points on his licence.
