Nursing prerequisites

Hi, everyone

I am a 28yr old mam, currently working as an RPN,and interested in becaming an RN. My husband and I will be moving, next year to the States (form Canada) because of his work. Meanwhile I would like to take all the pre-requisites for nursing, but I don't know what they are. Here we have only degree program(4yrs) for Bsn,and the requirments are high school diploma and 6 grade13 level courses(biology, chem,math...). Psychology, anatomy.. are part of the nursing program. My question is: what are the pre-reqs for diploma and degree program, how many years and the tuition fees?

Any input is very appreciated.

Thanks.
