I'm hoping you have already made it into a program!
I did attend NU then transfered to CSUSM. When I went to apply there were several classes from NU that did not count towards the pre-reqs. I ended up with too many units that didn't count for anything. It bumped me out of financial aid eligibilty. For example: I took NU's stats class and got an A+ (I could not believe it!), however none of the community colleges nor CSUSM would accept the class as credit for math or stats.
If you have not been accepted, I would go to an informational and ask which classes will transfer. I was able to transfer some of the classes into CSUSM, but I was told this past fall that they were changing what they would accept. Although I had achieved A's at NU I had to retake classes at the community college and through CSUSM extended learning to apply. If you can't get answers that way, make an appointment with an admissions advisor (not nursing, regular admissions). Take your cataloge (spelling) and transcript (even unofficial) and ask if those classes are accepted as transfer ans specifically fill which requirements.
Lastly, you will need to take the required chem classes for CSUSM. I was told directly that CSUSM would not accept any online science classes from NU. At the time those were the only ones available to take in my area through NU.
