OEM practice questions - frequently asked questions

Plain answers about how OEM Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real OEM exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The OEM exam spans 7 domains: Clinical Occupational Medicine (48% of the exam); Health, Wellness, and Human Performance Optimization (8% of the exam); Work Fitness, Impairment, and Disability Prevention (15% of the exam); Hazard and Disaster Prevention and Management (8% of the exam); Environmental Medicine (8% of the exam); Occupational Epidemiology, Analytics, and Research (5% of the exam); Systems-based Practice and Administration (8% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Clinical Occupational Medicine 48%; Work Fitness, Impairment, and Disability Prevention 15%; Health, Wellness, and Human Performance Optimization 8%; Hazard and Disaster Prevention and Management 8%; Environmental Medicine 8%; Systems-based Practice and Administration 8%; Occupational Epidemiology, Analytics, and Research 5%.

The OEM exam has 200 questions and is completed in 4 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
