I enjoy a lot this course, remembered me when I was in the university. This is very interesting now for me.
The instructor is a great communicator and very engaging. I appreciate Sean White's ability to tease out all the details in a complex issue, look at that issue from several angles, and then return to that issue in a later module to make sure that we as learners understand the issue.
this is a very good course an its alot to learn all at once especially if u have no background in roofing or solar installation so plz take it very serious
