I also felt as though alot of the questions were theory, eligability, and care models. My hospital purchased the computer questions and I did all of those, there was one with 750 questions with rational and another with a pretest/course/postest. I don't know how many hours I spent, but I should have spent less time on disease process, treatments, and pathophysiology. My test just turned off, I figure that at least if I have to retake in December I will know right away.
