This is the only reason I passed my nremt. I studied from only the book the first two times I took it, and surprise surprise I failed both times. The third time I studied I used this app every day for a month, and finally I Passed. I give all the credit to this app. I started with the study cards, once I had all the cards down for the section I would then take the quiz. Once I finished all the study cards and all the quizzes I moved on to the tests. This app really helps you prepare for how you should answer the questions on the nremt.
