SPI practice questions - frequently asked questions

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

The SPI exam spans 5 domains: Perform Ultrasound Examinations (23% of the exam); Manage Ultrasound Transducers (7% of the exam); Optimize Sonographic Images (26% of the exam); Apply Doppler Concepts (34% of the exam); Provide Clinical Safety & Quality Assurance (10% 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: Apply Doppler Concepts 34%; Optimize Sonographic Images 26%; Perform Ultrasound Examinations 23%; Provide Clinical Safety & Quality Assurance 10%; Manage Ultrasound Transducers 7%.

The SPI exam has 110 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
