Unfortunately this seller does not know that a "USED" copy means that it is NOT a xeroxed copy of the Hesi NCLEX Review.I would warn anyone from buying from this seller. She retaliates by writing slanderous material on her feedback site.Buyer beware. Hesi actually sent me the REAL book which is very different from her rendition. I am still waiting for Amazon to pull her feedback excerpts since they violate their own policies. Responses seem to be automated. Its hard to rate a book which was developed to fraud the buyer. The original book is what I would recommend in buying. It has alot of detail to it. DO NOT BUY FROM RESNICHKIN....
