CRES practice questions - frequently asked questions

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

The CRES exam spans 6 domains: Anatomy & Physiology (7% of the exam); Fundamentals of Electricity and Electronics (10% of the exam); Healthcare Information Technology (25% of the exam); Healthcare Technology and Function (25% of the exam); Healthcare Technology Problem Solving (25% of the exam); Public (employee, patient, visitor) Safety in the Healthcare Facility (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: Healthcare Information Technology 25%; Healthcare Technology and Function 25%; Healthcare Technology Problem Solving 25%; Fundamentals of Electricity and Electronics 10%; Public (employee, patient, visitor) Safety in the Healthcare Facility 8%; Anatomy & Physiology 7%.

The CRES exam has 165 questions and is completed in 3 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
