This has been a big problem at our school as well. The questions aren't jiving with the assigned reading or lecture and we've been talking to the faculty about it.
I think there are many reasons for this problem:
* A lot of times, the teachers who teach the material don't write the tests. They're using some other teacher's tests or they're using test bank questions with content different from what's assigned or taught. So something that should have been mentioned in lecture that you wouldn't find in the assigned reading isn't covered and everybody ends up missing the question.
* The teachers often don't update their material. If the textbook edition changed, they assume the same material is in the new book when, in fact, it's not. It may be in the book but, the publisher has moved it to some other chapter that has nothing to do with the topic at hand so, there's no way you would find it.
* As you advance to new semesters, the teachers give you much tougher "critical thinking" questions where you're supposed to figure out the better of two right answers with limited information. They're also expecting you to remember everything you've been taught going back to physiology so ... unless you have a phenomenal memory ... it makes finding the right answer all the tougher.
Nevertheless, it really boils down to the fact that the teachers are too lazy to write their own tests. They're using other sources for the questions so they don't have to bother writing their own and, they assume it's all the same information when, in fact, it's not.
I don't know what the solution is because, despite our best efforts to bring these issues to the faculty's attention, nothing has changed. A lot of us are now using every NCLEX study guide
we can get our hands on to learn how to "game" the tests better because, the questions we are getting on tests often have nothing to do with what we read or covered in class.
People who have been taking this approach ... i.e. studing NCLEX guides more than the assigned lecture material ... have been doing better in my class. They still study the material but, they focus more on the NCLEX guides.
