Well, yes, I thought it was hard. (mostly the prioritizing and drug questions )
My PN program was more difficult than my arts & science program, and it was also harder than my Cosmetology school program. I feel like my whole last year, I did nothing but read , take tests, eat and sleep every now & then, and once in a while I got to see my kids and husband.
But, I think the PN program was easier than the RN program i'm in right now.
Good luck, the time goes fast at least
