Sorry, I'm not from Nebraska, so can't help you with personal experience with the schools
there, but if you call your local colleges, they should be able to tell you what their requirements are (they vary by school), and how long the wait is. Some schools have waiting lists that go by the order that a person signs up, and some have lists where the higher GPA's are put at the top of the list.
I'm not an experienced nurse, merely a student
, but I worked as a CNA on a med-surg unit before getting into the program. The experience has helped me a great deal in my clinicals and also it has helped me to understand some of the concepts taught in class. I would recommend trying to do something healthcare related, either a job, or as a volunteer, so that you can observe what nurses do on a daily basis. A few people in my program dropped halfway through the first semester, because they discovered that nursing wasn't what they thought it would be.
Good luck in whatever you decide!
