So go get your RN anywhere you want... community college, or an accelerated BSN program (typically an accelerated BSN program requires you to have a bachelors degree in something else before you can get in). Then you can go to an NP program program. But I’m aware of no other straight forward way to become an RN without going to an actual in class school to become one. There are skills labs and clinical training that is required to get an RN.
