The course is actually pretty good and as an alternative to 3 points it’s a no brainer. If you are convinced it is a waste of your time then take the 3 points.
There are lots of Cameras on the A4 from Chiswick Roundabout. There are two on the approach to 'ammersmif, one just before Sainsburys in Kensington and then a further one next to the Natural History musieum. Unless you are running Arab plates you should slow down.
Did one courtesy of Herts plod. Do stay awake or they will chuck you out and give you the points and fine, and no you dont get the course fee back…As a lady on the course discovered, mind you there wasnt much point in her being there as she hardly spoke a word of English!!
