Thinking about going to school for acute care NP however I didn’t ’ have the best nursing school gpa (2.98) had some unfortunate events happen during that time. I am currently a ICU nurse with 5 years of experience . Do I have a chance?

If you REALLY want that as a career path...NEVER GIVE UP!
Be persistent in applications. MORE important be upbeat and show off your personality during the interview. Educators do not want duds! I have had bright students who I would not have accepted becasue they lack ability in empathy and good hands on patient care. Go out there and STRUT your stuff!
