NLN Pre Entrance Exam?
That is the test that some schools use as part of determining whether or not you will be accepted (ours weights entirely on the score you get from this test, but other schools look at other things such as GPA). It is a test that has 3 sections...Verbal, Math & Science. I would check with your school, find out when the cut-off date is for applying and whether or not they have anymore test dates prior to that cut-off date.
Our cut-off was September 5 and our last test was August 28.
Before you take the test, I would suggest getting the Study Guide and going over it again and again until you feel like you know the information. Here is a link so you know what the book looks like - you can probably search Ebay for it though.

If you are not referring to the Pre-Entrance Exam, then I am not sure what what it is!!!
It might be that your school does not use the NLN exam for entrance. I know some schools out here don't.
