30+ years ago I dropped out of school without doing it properly, which left me with 11 units of F. When I went back to school 20 years ago, I figured out that if I got As in ALL of the rest of my college classes (up to my BA or BS), I STILL would never get above a 3.4.
I now have one more class before I get an AA in Lib Arts in June and I didn't get As in the rest of my classes (As and Bs, no Cs), and I STILL don't have a 3.0 GPA!
So last spring, when I decided to go into nursing, I talked with the nursing school counselor. She told me that they don't care what we've done in the past. What they want to see is how we've done in our classes in the past couple of years and what we've done in our pre-reqs. I hope she is not BSing.
And I hope this helps you.
Go for it! If you want to be a nurse, there will be a way for you to do it!
