How do you rate my chances

Hi y'all, I'm a 20yr old Indian male currently attending the University of Oklahoma. I've wanted to have a job in healthcare since I was a child and I graduated HS with the hopes of being a doctor. I come from a really small town so the freedom of college got to me my first 2 years leaving me with a gpa of around 2.1. This is when I started questioning what my calling in life was, one thing I enjoy more than anything is helping someone and putting a smile on their face and that's when I thought about nursing. My interest in nursing started when I was volunteering at my local hospital, all the nurses LOVED their jobs I never heard anyone complain about anything and they really bonded and connected with their patients. I know this is the profession for me and it is my dream to become an RN. I only wish I had known this coming out of college so I wouldn't have wasted 2 yrs leaving me in an academic hole. I haven't taken any of my science pre-reqs yet and I know I can make a 4.0 if I apply myself, my question is would a 4.0 science and 2.7-3.0 cgpa get me in anywhere? I'm extremely disappointed in myself for taking my first years so casually, I still had a teenage mentality but I have changed into a much more responsible person. Thanks for reading and any advice would be much appreciated
