MCG, I am not 100% certain on the answer to your question on exemption for the course. The course covers the History and role of the Air Force, sentence structure, punctuation and Grammar, Briefings and Human behavior, Selection boards, Air Reserve Management and a few other lessons. There is a requirement to do a Quiz on the various subjects, a couple of Exams (alll multiple choice), an Essay on Air Force History and a Powerpoint presentation. Make sure your chain of command reads and understands the "Learning Contract" your unit will have to fill out and that they provide you with the appropriate time to do the lessons and PCs (mine did not initially and it almost cost me the course). It is not a hard course to do, the staff are easily accessed through email or by phone and are more than willing to assist you in any way they can.
Edited because I am an idiot.
