Congrats!!! .. I just graduated this year at 41..
.. I owned a small business for 11 years before going back to school, and hadn't been in a classroom for a total of 14 years before starting. No previous experience in healthcare either. I'm a quick study.
I can't advise on an accelerated program as I did a traditional BSN, but I know the accelerated students at my school were like a family. Very close, and a very intense 16 straight months for them.
I'd say enjoy your freedom right now, cuz it's gonna be all school, all the time when you start. If you do want to prepare and get a leg up, I'd suggest to start looking a med classifications, (notice common suffixes of the multitudes of drugs within) indications, actions, common side effects, contraindications, etc..
Way to go!! So exciting!! Best wishes to you..
