I cannot remember. Just a small amount because I do remember I paid the local ag dept in cash. The invoice was passed to my accountant together with all others for 2015 last January. It would a guess to say about €10. Given the number of people who attended that would well cover the costs of those who ran the course.
Bear in mind that those attending were very small scale people who cannot possibly make even the min wage (€505 a month) from their land so cannot afford big fees either. There were a lot of women on the course, and I suspect that was because they could read and their husbands cannot.
I paid £250 for an hour , most of which was the inspector telling me about his life in Australia ... wasn't you was it.?
