If you want to enroll in ROTc program and get a scholarship for nursing school you can do it before you are 27. There is another option, you can just go to school, pay with your own money, and then after you get your license become an army nurse (they will pay your loans, j ust make sure you apply for the program before you graduate, somehwere in your junior or senior year). But in both cases you need to have a BSN, so you are better off goinf for a BSN directly. Having an LPN will not help you skip the waiting list.
