The course content was very good and I can see myself using a lot of the features demonstrated today. It was a bit challenging during the morning session with one participant who did not have the most up to date version of the software, which was hard for her, and also held up the session a bit. The afternoon session flowed better and I got a lot of value out of the dashboards and slicing. -Analysis & Dashboards Brisbane
