I took the NLN also before applying to nursing school here in Southwestern
IL. It is required and they used it along with course prereq completion, grade point average and also prior medical experience.
From what I was told they accepted all those that scored 110 and higher.
If there were still openings after that then the program took the students with scores closest to 110.
I scored a 122, I agree it had nothing to do with nursing. The instructors
said it showed what one learned from all those prereq classes.
Best of luck to you!!!
