The 100 for EMT: How to Not Bomb This Exam breaks EMT exam preparation into 100 high-yield concepts every student should understand before facing the NREMT. Each topic includes a realistic question, detailed rationale, trap analysis, two alternate questions, and need-to-know takeaways designed to strengthen clinical reasoning, prioritization, and test-taking judgment. To build the book, we analyzed thousands of records from unsuccessful EMT exam attempts, organized the results into a working database, and identified the 100 subtopics most consistently associated with failure on the EMT exam. The result is a focused review system built around the areas students are most likely to misunderstand, overlook, or answer incorrectly. This is Book One in a three-part series. The 200 for EMT: How to Ensure You Pass This Exam will expand the review to 200 essential concepts, while The 300 for EMT: How to Ace This Exam will complete the series with the depth and breadth needed for students aiming to perform at the highest level.
