Yes, and it total agreement with grasscarp, although in 10 years less driving – although I did learn one thing from the course.
I can advise that the courses are just a money making exercise (and nothing more) – but they don’t want you to know this.
Having to take the course within 3 months, I looked online at five possible venues within reasonable distance and the available dates. Each of the five venues listed dates available to me. From memory, each venue had an available date approximately every other week (offering either a morning or afternoon session).
I can advise that at the location I attended, 50 persons were booked each of the days sessions (100 in total). Given the above information, you might surmise that within what I consider a reasonable distance of where I live, around 50 persons per day are attending such courses.
On arrival at the venue (an hotel), I asked the concierge how often the courses were run at the venue (knowing that I had been offered one date in every two weeks); he replied that they are run every day.
Given this information, you can surmise that within what I consider a reasonable distance of where I live, around 500 persons per day are attending such courses.
