CER practice questions - frequently asked questions

Plain answers about how CER 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 CER exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The CER exam spans 7 domains: Microbiology and Infection Control (12% of the exam); Endoscope Purpose, Design and Structure (10% of the exam); Work Area Design (12% of the exam); Endoscope Processing Steps (32% of the exam); Endoscope Handling, Transport and Storage (16% of the exam); Endoscope Tracking, Repair and System Maintenance (10% of the exam); Human Factors That Impact Endoscope Systems (8% of the exam). Every practice question on this site is tagged to one of these domains.
