I checked on May 7 and the "Download Exercise System" button was there in the Overview section of the course and I was able to start the download. Please try again. There is no cloud option for this course at this time.
I have managed to download the UI Specialist exercise system and installed VirtualBox on my Mac as well as launched Pega & DesignerStudio on my browser. The issue is I only get DMSample and PageRules applications. What do I have to do to see the UI Specialist course exercises?
