The navigation for the course was strangely set out but once I knew to go to the menu at the top it was ok. I found the material to be basic but informative and I learnt a lot. The voice was a little monotone and would have preferred to hear the course rather than reading it all (just my learning preference). The multiple choice test at the end I was dreading as the course material was long and I feared I may have forgotten some of it but I only got one question wrong, I was well chuffed. It may be better to stage the test of understanding at the end of each unit. Hope this helps, thank you for the fast delivery of the certificate.
