Only speaking for myself here, but when I did my Bachelor of Aviation course the only things I learnt were how to drink and how to manage time, especially around exam time when I'd rather be drinking. Without that degree, however, I wouldn't have been able to get into the Masters of Aviation Management course that I am currently doing - and find excellent... and am learning heaps of stuff that interests me greatly.
I think Bachelor of Aviation courses definately do have their place in our industry, and are just another step along what is hopefully a long career for all of us.
