my theory is if you have all the appropriate aviation quals (ATPL etc)..why bother with worrying about course credit.
enrol in a bachelor of science or business..do some psych some management some business subjects in general and round out your experience.
theres always use for these as a CP or in a training or management capacity later on in your career.
And yes there is way more to life than aviation.. and theres benefit in studying almost anything.
Just my opinion, but i must be a glutton for punishment...being in aviation AND studying part time for 10 years!!
