Having previously undertaken a similar course in the past I expected this course to not be especially beneficial, however this was not the case at all. I have garnered some very useful new skills and knowledge. The trainer's subject knowledge and delivery are a credit to himself and Stayahead. I was constantly engaged and rarely found myself requiring a repeat of the coursework but when needed he was more than helpful in explaining where I was struggling.
