Thanks to all for the helpful advice. I have tapped into a number of sources and put together what I think is a pretty good study guide, but we'll see. I take the test on the 30th. If needed, I will be coming back to find a good online course.
I'm scheduled to take the FAA Part 107 Knowledge Exam for sUAS Operators License. Has anyone found good online study materials for this? Also has any else taken or preparing to take this exam?
