I will be honest and upfront and say that I have purchased test banks. I will tell you that I have yet to get a test with any of the questions from the test bank on them. If you are relying on them to pass a test, you will be in trouble. We were informed at the beginning of our nursing education adventure that the teachers write the majority of the their OWN questions, and don't even use the test bank. I used the test bank as a study tool, and it did help quite a bit. I got a couple of Bs but mostly c's (when 80% or higher is passing). It was a great study tool because a lot do not come with rationales. I would answer the question, write my rationale for the question, and double check myself with the book. It actually helped me retain a lot of information because I had to rationalize the answer and explain to myself why it was either correct or incorrect. It's also good practice on how to answer questions. Nursing is a lot of application. If you're expecting to memorize nursing, you are going into the wrong career.
