Not sure if it has already been mentioned but, I downloaded an application off the Apple Store called EMT Review Plus by Limmer Creative. The App was $10.00 but helped astronomically in studying. I only used the App to study, no textbooks.
120 Questions, Passed. Just a tip; do not take the NREMT right before Christmas! My test was taken on the 23rd, I received my results on the 27th, you'll be waiting for a while for your results if taking the test right before any major holidays. Best of Luck to all whom are taking the test!
