I decided after 6 years of being a CNA that I could be a nurse. I only needed the piece of paper that said I was a nurse.
I agree that it would be more worthwhile to go for the ADN rather than LPN to RN. The nurses that I have known have lost time in doing it that way.
I also agree with talking to the financial aid office at your school. They have pretty good connections. There are scholarships
from all kinds of nursing organizations, that are specific to locale. There are also opportunities from different facilities. Where I work, an employee can apply for assistance, and have to maintain a certain grade point, but that shouldn't be a problem.
I was 40 with a part time job, a husband and 3 teenagers. I was busy, but I enjoyed 90% of it.
Good Luck and God Speed on your chosen path.
