The process of creating a course shell and adding content is something I am very familiar with. Among all the LMSs I have worked with, Schoology is, in my opinion, the easiest and most intuitive management system.
After creating a new course, which I named TOOL Section 1, I clicked on Add Materials and then on Add Web Content. I attached the zipped package provided in the 3.1.2 quest, and I finally clicked on Submit. These are all the simple steps that are necessary to complete in order to fully load a zipped package and make it viewable.
