Bill I must thank you for a very enjoyable course. I have to say that, the way you developed the information was first class – the delivery was fluent, natural – in fact it came across as extemporaneous!  It was also very informative about the subject so as to enable us to undertake the practical aspects out on site. I don’t profess to be an expert in such matters – but I thought it was very well done and it’s no surprise that your pass rate is high. ( I just hope to be in that statistic!)
