Sounds like a mistake if I'm reading your post correctly. So you haven't taken anatomy, physiology, chemistry, etc.? If you haven't had some version of the afore mentioned classes then you're likely going to have a really tough time w/ nursing school
What kind of program are you in? Are you at a university as a freshman, or are you at a community college or trade school? Most schools
have you create your own schedule with the assistance of a couselor. If you are enrolled as "pre-nursing" maybe the all nursing courses are actully the pre-reqs that you will be needing.
Heck, I don't know but something seems fishy. Also, most schools I know of (in California anyway) have the pre-reqs as just that, a pre-requisite to applying to nursing school. I had to have all mine done or almost done before I could apply to different nursing programs
Call the registration office or make an appointment with a counselor. Good luck.
