Hello I am currently enrolled in the ABSN program at UNC. Your master's gpa is good and keep volunteering. Also I was told by a member of the admissions committee that your science gpa is the biggest predictor of doing well in the program. SO make sure to do as well as you can in the prereqs. They also look for research exerience. If you are very serious about applying call the UNC-SON dept and speak to someone about enrolling. Then make sure and metioned your conversation in one of your essays. Good luck.
