No problem! You can ask me anything. :)
The references, from what I heard, was supposed to be filled out with the accompanying application. However, you should call them and verify.
Let me give you a piece of advice on the NLN book -- forget the reading portion, okay? You either know it or don't. I suggest reading an SAT book instead. The Math is dead on -- so practice, practice, practice! If you see a question on the NLN exam that doesn't pertain to the NLN book then skip it. Chances are those questions aren't counted. For the science, I had a lot of physics questions. Maybe 75% of it. I suggest you grab any highschool physics textbook and skim around it. Also, BOZEMAN SCIENCE on youtube helped A LOT for the science portion. He explains it very easily.
You got this, okay? Don't sweat it. Pray, meditate, etc. I didn't have the highest GPA myself when I got in.
Eh, I'm doing well, but the exams are relatively harder than last years (I was told this from a friend who graduated there.) However, there is tutoring, plenty of books, and resources at your disposal. The professors are phenomenal and the students got your back.
