I knew even before I graduated high school (2010) that I wanted to be a nurse. I had the same problem on choosing which path to take. Luckily for me, everything worked out just fine.
I started off at my city's community college(cheaper than uni), took all my pre-requisites and enrolled for their ADN program. I didn't got accepted, my advisor informed me that they prioritize students with more 'experience' . I was very disappointed. However, I also applied to a few universities for BSN. I was accepted to one of the best, if not THE best, university in my state. They offered me 1700+/semester transfer scholarship based on my GPA. Another university offered me the same tuition rate as my old comm. college(which is much cheaper than the traditional tuition rate).
My advice is for her to do her best in all the classes she takes. Whatever path she'll end up with, her grades can really help(get in the program, scholarships, etc...). And one more thing, she'll need YOU. Not only financially but for emotional support. I can say that my first semester with nursing classes was by far the wildest semester yet. So much stress and break downs, I was lucky my parents were there to give me strength when I was ready to give up.
Good luck and God bless to you both.
