Well, I will tell you that I had a bachelor's degree before I did nursing school
. I did my prerequisite courses (2 semesters) and then did as Associates degree (3 semesters) at a community college. Each semester was less than $3,000, including books. I worked full time through it all. So, that was 2.5 years and less than $15,000. I worked right after graduating and at the same time earned my BSN in one term ($3500) from Western Governors. So, I spent 3 years and well under $20,000 for my BSN.
Some will I could have been done in it 1.5 years and worked as a nurse quicker. I like the way I did it. No debt! But it's for you to decide what's best for you.
