If you are preparing to take the National Registry Exam for your NREMT-B exam, or trying to pass your EMT course, this study guide is for you. The EMT Tutor includes 4 practice tests, each with 100 questions, answers and full explanations. It also includes self-assessments to determine which areas you may need to study more than others. Short tutorials and study guide tips are also included. This study guide is intended for those that already have some EMT knowledge. It is not intended as a textbook, but simply an aide to help you study. We also have an EMT Tutor app (and other EMS apps) in both the Apple and Android markets which also includes flashcards, scenarios, skills sheets, and differential check outs.
