Congratulations on your interview, Alexa!
My TEAS score was 90.0% overall. My individual national ranking was 99% and individual program ranking was 99%. Individually, I got 95.0% on reading, 86.7% on math, 90.0% on science, and 89.1% on English. It's ironic that of all sections, math was my worst part! It's because they throw all these laborious and time-consuming arithmetic calculations at you, and I didn't watch my time well enough to finish the section. Most people have problems finishing the math section on time, so be prepared. I'd suggest skipping the math problems that look extra long so you can finish the math section. Unfortunately, the TEAS we took was an online test, and we could not go back to check or change previous answers.
Also, I got a 4.0 GPA in all my nursing prerequisites for two years. (I also took and got A's in extra courses: pathophysiology, pharmacology, cell biology, genetics, physics, and Spanish.) In high school, I got 1500 on the SAT (720 Verbal, 780 Math), and I included a copy of my high school transcript, though it and the SAT are not required.
Interview tips? Be positive, show how you have successfully handled high pressure situations gracefully, that you are tough (mentally, emotionally, and physically) and can deal with regular criticism from clinical instructors and patients, that you know what a nurse actually does day-to-day, and that you are highly driven/focused/organized. Convince them how much you truly are committed to succeeding in their extremely difficult program.
Finally, make them laugh! For example, Rush students have a 100% pass rate on the NCLEX. When my interviewers mentioned that, I joked "I've been wondering about your famous 100% pass rate. Do you guys have a dungeon for all the students who don't make it there? Are they locked up somewhere and never heard from again?"
They both laughed.
