Please don't purchase the Netware Training Guide by accident, as I did. It was listed first on Amazon on the page that I looked for for CNA (Certified Nursing Assistant), but I was looking for Nursing Certification and not Netware. So it was a costly mistake as I only received about half of the cost of the book when I returned it. It was my fault because I just noticed the big CNA and because it was the first listed on the page with the Nursing training books and CDs I just took for granted that it was also about nursing.
