I never used a specific PAX study guide. It was similar to the HESI A2
contnet. I took HESI A2 twice (once at each school, because the school can customize that exam,) I took NLN PAX once. The English was almost identical on the HESI & PAX.
I had a HESI A2 study book, the free download of the McGraw Hill nursing pre-entrance exam book, a Cliff's Notes General Biology, a Cliff's Nursing School Entrance Exam study book, and a GED math book. Overall, I took the HESI 2x, the PAX once, and a couple of TEAS or Workkeys or some such tests for LPN before settling on the school that I attended. Scored very high on all of them, very easily.
Somebody posted a link of here for a free HESI study guide download, and I got the link for the McGraw Hill on here, too. Search, and you'll probably find them. The HSEI link was just posted with the past month or so.
