I am taking the CPNE at the Racine, WI site June 6th. I have been preparing by studying the EC workbook. I have heard that a lot of people attend their workshops and feel like it helps so much. I can't afford the workshop nor do I have time to get into one. Has anyone passed the CPNE first try that did not use anything but the workbook that was supplied. Was it difficult for you? Any info about what I am about to go through would be great! Thanks!
