How do you make a course like the PDSD tolerable let alone interesting? It’s very difficult! Virtual Training Centre have given it a good shot. The course is well laid out and easy to follow, and if you make a mistake, then go back and try it again, it’s the best way to learn. When I called them to clarify some points that I had, they were clear, helpful and polite. I wouldn’t hesitate to use them again if I needed to.
