I got into these 3 schools for nursing but I wanted to know which one has a better nursing program?
Just based on selectivity, I would choose CSUF.
All 3 will be fine for nursing. Unless you have a good reason to attend the others, like it is substantially cheaper, an easier commute, I agree - Fullerton is probably the place to be.
Fullerton overrides LA and SB easily in terms of overall reputation (especially the area, you got Disneyland, the beach, Knott’s, and more stuff too).
Just be aware though, with a school population 38K~, it will be difficult to be noticed…getting classes will be a pain and you will have to work hard if you want to graduate in 4 years.
Good luck! Congrats on your acceptances.
