Make an appointment with your instructor to discuss the test and ask for help. We (here on AN) can't have any idea of what you did wrong or provide any real assistance.
And, as a nurse educator I have to (really really have to) tell you that the whole Learning Styles thing is absolute bunkum - no evidence at all to support them. It is true that people may have a preferred
method of learning, but that does not mean that they can learn just as well with other methods. Educational research has shown that the only student factor that has been shown to have a significant effect on learning outcomes is prior knowledge. If you have some prior knowledge of the subject, you should use different learning methods than if you have absolutely no prior knowledge.
So - don't despair if your instructor is not presenting information according to your 'learning style'... it really won't doesn't make a difference in your ability to learn.
Nursing education is challenging because it is a complete 180 from traditional education - especially if you are young enough to have been victimized by the "no child left behind" curriculum that has been in place for the last 10 years. This focused entirely on passing standardized tests & pretty much eliminated any creativity, development of critical thinking or metacognition (learning how to learn) skills. But nursing school
is the complete opposite - stress is entirely on the application
of knowledge rather than memorization of factoids. We've all been there, but my point is that it is even more difficult for the current generation than it was for us oldies.
