Pass the ARDMS SPI Exam
Prepare for the ARDMS SPI exam with a 110-question practice simulator, 200 ultrasound physics flashcards, 50 Physics Pearls, and domain-focused feedback developed by an RDMS instructor.
You don't need more material. You need the right material.
Two paths. One decision.
Study everything. Hope it's enough.
Read the textbook cover to cover. Do random practice questions. Walk in and find out which domains the exam actually weighted. If that doesn't work — pay the retake fee.
Focus on the current published SPI content outline.
Each exam attempt pulls 110 questions from a 155-question bank covering five study areas aligned to the current published SPI content outline, with a per-domain breakdown after every attempt. You see exactly where you're losing points while there's still time to fix them.

If any of these sound like you, you're in the right place.
Most students don't know what they're weak on until they lose points for it.
Retaking the SPI delays every specialty credential. Our simulator's per-domain breakdown shows your weak spots while there's still time to fix them.
Get the Bundle →Your program covers procedures. SonoPrep covers the physics.
Most clinical programs don't spend enough time on physics — which is exactly what the SPI tests. 50 Physics Pearls and 200 flashcards fill that gap.
Try the Demo →The problem wasn't effort. It was coverage.
The SPI tests 5 domains at specific weightings. If you didn't know which questions came from which domain, you couldn't prioritize. Per-domain results show you where you're losing points.
See the Simulator →It's not that they didn't study. It's that they didn't know which domains would cost them.
The published outline allocates practice topics in approximate proportions.
Five domains. Different topic proportions mean a focused review plan can be more useful than treating every topic identically.
Blind spots don't surface until test day.
You can feel prepared and still fail — because you never identified which specific domains you were actually weak in.
Broad studying creates false confidence.
Reading a textbook cover to cover feels thorough. But the SPI tests how questions are framed, not just what you know.
The useful question is which practice areas deserve your attention next.

This demo uses the same question interface and scoring engine as the full SonoPrep simulator. The full SonoPrep simulator presents 110 independently written questions per practice attempt selected from SonoPrep’s 155-question bank, with answer explanations and per-domain analytics.

What SonoPrep is not.
Not a textbook.
Structured SPI prep covering five study areas aligned to the current published SPI content outline — not everything the field covers.
Not random questions.
The full SonoPrep simulator includes three practice attempts. Each attempt presents 110 independently written questions selected from SonoPrep’s 155-question bank.
Not a subscription.
One payment. 30-day access (45 for the bundle). No recurring charges. The bundle is $99.
"What if I go through all this and still don't pass?"
10-day full refund. No hoops, no questions. We're confident enough in the material to make buying feel safer than not buying.

A failed SPI isn't just a failed exam.
It delays every specialty exam behind it. It means paying ARDMS fees again. It means explaining the gap. And it means more months studying material you may have already gotten wrong once.
The SPI covers a broad physics outline, so focused practice and targeted review can make study time more efficient.
For students testing in 2–4 weeks: every day you wait is a day you could have found a gap and fixed it. The demo takes 2 minutes.

This content was taught in a real classroom before it was online.
SonoPrep's curriculum comes from study materials developed at Houston International Cardiotech Ultrasound School — where the RDMS instructor behind this content spent years watching students struggle with physics, then pass their credentials.
Content is developed for focused SPI practice and reviewed for clarity before publication.
Questions are distributed according to approximate proportions based on the current published SPI content outline. SonoPrep questions are independently written practice questions, not official ARDMS exam questions.

Curriculum with a documented track record
Same methodology used at a Houston ultrasound school where students passed RDMS, RDCS, and RVT exams.
Content written to ARDMS specifications
Practice content covers five areas using approximate proportions based on the current published SPI content outline.
