I have also covered about new columns and measures what the main difference is between those 2. Also covered very basic DAX functions, explained about the date dimension, Bookmarks and drillthoughs.
Next week I have asked everyone to pick a dataset on their own and come up with their data visualisations. So waiting for their creativity to unveil.
Also wanted to thank @Reza and @Leila from #Radacad for sponsoring biscuits for kids. They have been enjoying them for the last 3 classes.
