Other than to be an officer in the military, what other use exists for a 3 year general studies under-graduates degree from Athabasca university ?

I don’t know why you frame the question as just for Athabasca University. The question pertains to any university course of studies. But general studies is not a major; a University course of studies is generally in a major with specific courses. To that end, it would seem to meet what you are interested in that a course in Business would be appropriate.

3 years of college is not adequate education to be U.S. military officer. The college will only give you a very slight boost up the enlisted ranks. And there is nothing wrong with that.

If you are interested in accounting, keep working to get your BA and then assess your options.

Good luck!

Don’t give up.
