I would work as an LPN for a few months to a year first. This gives the you chance to pay down some of the debt (after all the longer your debt sits on credit cards, the more you owe). The most important thing however is that it will give you real world experience. This helps a ton in class. It gives you an insider prespective.
Also like someone said, most employers offer some sort of tuition reimbursement to help. My particular facility only offers 2,000 a year, but it helps!
Are there any grants you can apply for? I had grants for the majority of my nursing education until the last year, and then my tuition remibursement covered most of that. That will help with college costs as well.
I know many people dont work during the nursing program, but it is possible to do both. I am the primary provider in my family (with 2 kids) so I didnt really have a choice. I was busy, but did both. In the end I provided for my family, had real work experience, have current work experience, and graduated last week.
BTW Im an unusal LPN bridge as I entered into the RN program, did the first year and the LPN option then took some time before going back (which also meant I only had two semesters left, not 15 months). However for our college, to enter as an LPN bridge you had to have worked as an LPN for 6 months to even apply. So make sure that isnt a requirement at your school of choice.
