The ASN has NO prerequisites; you learn everything, including A&P and microbiology and English, as part of the ASN program. (The BSN program is different; it is a junior level program that has a whole bunch of prerequisites.)
Here's a description of the ASN program:

And here's the curriculum:

The NET test is required for the ASN program; and you do need to score fairly well on it. Contact admissions for more info re: the NET.
Good luck!
