The cost is pretty high ($20,000 or so). You can find the NCLEX pass rates on the NJ Board of Nursing website here: http://www.njconsumeraffairs.gov/nursing/apps/NCLEX-PN.pdf
(NJ BON requires a minimum of 75% NCLEX pass rate, anything less requires the school to submit a plan of action to the BoN.)
In addition, the available financial aid is limited due to the type of institution (very few grants, if any and mostly loans (federal and private))
Ultimately like one other poster said, the education is what you make of it, you need to put in a good effort to get a good result. Most PN programs are accelerated/short term, so you need to be prepared for a fast paced academic environment and the focus and commitment required to succeed.
