So, here are my thoughts:
Option #1 If you are fresh out of HS or never have a bachelors then try for your BSN.
Option #2 If you have a Bachelor's in something other than nursing but want to change careers then get you ADN.
Now if you picked Option #2 think about this
If your GPA is not great after graduating with your bachelors and you want some experience then proceed with the ADN. You can still further your career and get your masters but now your GPA will be better (if you do will in nursing school
) and you will have work experience (which some master programs require).
Or you can skip the ADN program and just take the GRE and apply to master programs that accepts people with other bachelor's degrees. Some you can obtain you BSN and MSN in one swoop other skip the BSN part and give your masters.
I hope this helps!
