Not sure if it's of much help, but from what I've been told it's a mediocre school and that may translate over into their programs. I guess it doesn't compare to other NJ schools that are better known.
Have you checked their website out? I didn't see anything about a post-bacc, just this: http://www.wpunj.edu/biology/pre-med.htm. Looks like their website has a decent structure, maybe their post-bacc/pre-med program is not so bad.
