No, you are not odd at all. Believe me, those of us who have passed the NCLEX-RN felt the same way you do. I am not sure if I speak for others, but we sympathize with you and root for you. Although I passed the first time with 75 questions, I know that it was the grace of GOD who allowed me to answer the questions the way that I did. I left out of the room not knowing how I did. I can only remember sitting in the car and going over information to see whether or not I got the ones in question correct or wrong. Either way, I drove myself crazy.
Remember God allows us to go through things to see where our faith is and what we do when we doubt ourselves and even him. Go to this website: http://www.learningext.com/
which was created by the NCSBN. The saunders is great, but remember when answering the questions take the test as if you were really taking a test and just don't click to get the answer and then say, yeah that is what I was thinking. I found myself doing that and realized I was getting no where. If you get to a terminology or disease that you do not know, really try to learn it so that you can apply it. Look it up and try to compare them to similar diseases. Because the ones that you look over will be the ones on the test. And remember the questions or diseases that seem to come up more often than others really "mean" something.
And remember to pray in the morning, night and in front of the computer screen and tell God that he is in control and only he can help you through this. Say it outloud so that he may give you the strength to get through each question. He is in control.
You are in my prayers, you will do this the next time.
