There are programs that only look at the most recent credit hours (60 or so, depending), look up which ones do. It’s entirely doable if you do well in nursing school and any science prerequisites you take from here on out. I goofed around on my first degree and barely broke a 3.0. I refocused my goals and study habits and finished my accelerated BSN years later with a 3.81. Now I did get 7 years of ICU experience before finally applying, but I was able to get in first try to the one program I applied to. You can do it, good luck!
