To BSN or not to BSN, that is the question

Hi everyone, a little background.

I have a BS in Biology, didn't find it a good career choice, I'm completing a ADN (part time/evening weekend program) at a CC.

My ultimate goal is to be an ARNP/maybe MPH and who knows what else

1. Do I get some RN experience and complete the bridge program for people with a BS in something other than nursing? How long is long enough?

2. Do I go straight into the program?? It requires undergrad classes (around 12 credits) + graduate courses. BUT you do not get a BSN until you complete the entire program, including the MSN+tract.

3. Do I get a BSN (around 30 credits) while getting some experience and then do the graduate program?

Please remember that I've been a college student since I graduated highschool (almost 10 years ago) and although I love school; I'm a little tired and would like to have something to show for it.

Thanks

D
