RDCS practice questions - frequently asked questions

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

The RDCS exam spans 5 domains: Anatomy and Physiology (15% of the exam); Pathology (40% of the exam); Clinical Care and Safety (11% of the exam); Measurement Techniques, Maneuvers, and Sonographic Views (25% of the exam); Instrumentation, Optimization, and Contrast (9% 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: Pathology 40%; Measurement Techniques, Maneuvers, and Sonographic Views 25%; Anatomy and Physiology 15%; Clinical Care and Safety 11%; Instrumentation, Optimization, and Contrast 9%.

The RDCS exam has 150 questions and is completed in 3 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
