Csusm pre nursing?!

I applied to csusm pre nursing but my acceptance letter says undeclared. Does that mean that I can’t take the nursing prerequisites to apply for their nursing program?

From CSUSM Nursing website:
Our Pre-Nursing Core Science courses are only available to our CSUSM students after a minimum of one year of attendance at CSUSM.

I would contact an advisor at CSUSM before enrolling to make sure you are able to get the classes needed.
