Psssssst.......hey, I've got some insider information for you: The NLN is a walk in the park.
Even though I took it many moons ago, I was only in the middle of my pre-nursing classes---hadn't even taken Nutrition, Micro, or all of A &P yet---I remember going through this very serious, intimidating process (you even had to leave your purse in a locker and be escorted back and forth to the restroom!). I also recall zipping through the various phases of the exam, answering questions and waiting for the test to get harder.
It never did.
Not to boast, but I wound up with the highest score out of all 50-some people who took the test that day. The exams you take in nursing school
are harder than the NLN, trust me. If you know the stuff you've already studied, you'll sail through the thing with the greatest of ease. Go for it!!
