Wrong major on my college apps???!!!

ok so i wanted to but Nursing (BS) but i accidentally put Biology (BS) but underneath i said BSN to specify and if you don’t know what that is it stands for bachelor’s of science in nursing. is this a huge mistake? should i contact the admission office? It’s san diego state university btw…
i’s so scared

Yes, you need to contact admissions since their Nursing program is a direct admit and they do not consider alternate majors. Email then follow up with a phone call to confirm.
