I just took the NLN-PAX I was worried to death about the science section because of physics and chemistry questions. The overall test was not too hard. I used two study guides and studied for about a week. I just recieved my score and I scored a 132. Thank goodness my school only requires a 96....Yipppeee, I will be glad to help anyone out who has questions about the test or if you are interested in the study guides I have two that anyone is welcome to have, I can just mail them out. I hope this helps someone out there who is worried about the test.
