The women I was speaking to seemed to think that it had to be a related course, however it doesn't come across like that from the booklet AND she never really knew what she was talking about when it came to anything FAA or Officer related.
Was this one woman, or multiple women who you consulted? Were they in a Union St bar at the time? - they know more about the Navy than most actually serving. Perhaps she was standing on a street corner dressed in a Wren's uniform - in which case she won't know about pay, but she'll know what you will enjoy, and more to the point, what you can afford. She will certainly earn more than most officers.
