How are you supporting yourself now? I transitioned to working my pre-nursing career job part-time while I was in OU's accelerated BSN program. I also worked as an SAT/ACT tutor and a medical transcriptionist. It takes a lot of discipline, prioritization, and time management, but you can work during nursing school.
There are also nursing school loans and educational institution-specific loans you can take out. I did that as well. A Perkins nursing loan, which I did take out, can be cancelled after 5 years of work as a nurse in direct patient care. There are other loan repayment/cancellation options if you work in a non-profit setting or with underserved populations. These can be found pretty readily online.
In addition, the Nurse Corps scholarship
pays for nursing school if you commit to working a certain amount of years in facilities that primarily treat underserved populations. There are also lots of other scholarships
available for nursing students, including some through the nursing school itself. You just have to look.
I don't know about OU's Tulsa campus as I was at the OKC campus, but everybody in my class passed the NCLEX on their first try, so I consider that a sign of the quality of the education we received. Don't get me wrong though - I learned A LOT on the job, especially during my first year. OU definitely teaches you the basics and how to deliver safe patient care as a brand new RN though.
I believe after your first semester of nursing school you qualify for nurse extern jobs. Several people in my class worked at Mercy during nursing school as nurse externs.
