In reply to Anonymous: Lets be honest, it depends what you want to do with your life / career.. some jobs need a professional qualification .. other don't.
Personally, I have a business degree MBA and a wedge of other stuff and most of it hasn't really helped me do my job that much better ... (or maybe I'm just a bit crap?)
I also tried the engineer route, walked away, became business studies teacher, and now on operational / project manager .... so life is what you make of it.
On a more practical note, some degrees have bursaries attached to them which would ease the burden of student debt, especially if you are gonna restart a new course at year one again .. particularly nursing, OT, some teaching courses.. or maybe the old company sponsorship route ...
