I'm having trouble figuring out what I need to do to become a LVN/LPN transferring to an RN. I'm going to city college and taking nursing classes. For the nursing classes, are there specific classes for CNA, LVN and RN programs? I'm in a CNA class almost graduating from it, and after I take my CNA exam and pass it, do i go to college and take CNA courses again? I want to be an RN but I don't know if I need a degree after two years of college, or four years?
