Isn’t ASU nursing at the downtown campus? Don’t know much about it, but my initial impression is that being on the smaller split campus would diminish the overall experience. Do you start at the Tempe campus and move over for last two years? Commute? I would try to understand that.
Do you want to live in CA after? There are so few 4 year BSN programs at the UC level that I would think UCI is pretty prestigious. I don’t know much about UCI, how residential is it? What are the nursing facilities like?
I would look at the 4 year curriculum plan for both to get an understanding of your specific path. Do either of them include summer classes to get through? 3.5 can be a tough pull given how tough some of the pre-req classes can be, ie anatomy and physiology, microbiology, pharmacology, etc.
Have you posted on the CC Nursing board?
I would think that UCI would cost less? My initial reaction was UCI>ASU.
Google reviews, search the nursing board for comments on either school, good luck!
