The test is tough. I was extremely frustrated with the content difference between ATI and class lecture. I do watch the dvd's, which helps somewhat, but I have little time to read through the book. I don't believe our instructors even looked at the ATI books nor exam, so the answer is "yes, they really don't know". In regards to exam content being the same, well...some of my classmates had the same exam and some didn't!
This was the first ATI exam that I didn't pass on the first time through-in fact, no one in my class passed the first time. Unfortunately, starting next semester we will no longer be given a second opportunity to pass:o. I did manage to pass the Peds portion by starting the video portion EARLY and apply the video to the current subject in our lecture portion. There were still glaring differences in content, but the isntructor is always right (at least she is if you want to pass:)
