apply to programs and see. if your between the two it really comes down to what you want to do. I wouldnt say the ABSN is out of the way, your GPA is where they want it, it all comes down to pre-reqs. You would need to get at least a 3.0 for most of the pre-reqs to keep your GPA in range. Worst case, theres always ADN programs that take a year longer but you can get your BSN at the same time if you work your classes correctly (thats what i'm doing and ill get both my ADN and BSN at the same time and it only takes 19 months as compared to 13 at an ABSN program, also only costs a total of $42k. As far as looking at the gpa, they look at cumulative gpa, but from what ive been told, more emphasis is placed on the last 60 credit hours, and they look closer at the 4 year college grades. your cumulative gpa is around a 3.3-3.4 if im correct (ballparking it), which is good as long as your pre-reqs are good. However if you happen to get Cs in the pre-reqs it changes everything. Many programs will also look closely at the pre-reqs, especially A&P 1,2, microbiology, statistics, and a few other classes. so all in all, take the pre-reqs and then ask yourself which route to go.
But back to the matter at hand, if your looking for the cheaper, easier route then the social work is probably the way to go (i have friends who say its not as bad as their undergrad in psych). Nursing is competitive, its very much work, and you will be learning life long, and you need to decide if thats what you want. It almost seems as if you want to make a decision this minute, and thats not a good thing. you should take time to think it through, rather than make a decision. take the pre-reqs and then decide.
