Do I need a separate Physics book, or is an integrated SPI resource enough?

If this is your very first ARDMS exam — which for most candidates is SPI — I'd recommend a resource that covers Physics on its own, and working through it step by step. Once you've already passed SPI and move on to a specialty exam (Abdomen, Breast, and so on), those exams do include some physics-related questions, but not at a high weight — a short summary or an integrated resource is enough at that point.

Note-taking vs. repeated practice questions — which is more efficient for SPI?

Any advice on this is just a reference point, since no one else actually knows how you learn — you have to figure that out yourself first. Concept-first learners, who need to fully understand one idea before moving to the next, tend to do well with note-taking: work through one concept at a time and write it out. It takes longer, but what you learn this way tends to stick for a long time. Pace-first learners, who'd rather quickly grasp the core idea and review it repeatedly — even just by rereading — and who like jumping straight into practice questions to learn by doing, tend to do better with repeated question-solving: test, spot the gap, patch it immediately.

URR or MUT for SPI — do I need both?

You probably don't need both. It comes down to your learning style: MUT fits concept-first learners who need full understanding before moving on, URR fits pace-first learners who'd rather repeat practice questions and keep moving.

Prepry vs URR for SPI — which is closer to the real exam?

I haven't personally used Prepry, so I can't give a direct side-by-side comparison with URR. But here's the more important point, and it applies to any resource: ARDMS doesn't publish an official study guide, so every commercial resource — Prepry, URR, or anything else — is really someone's prediction of what the exam might look like, not a guaranteed match to the real thing.

Has anyone passed SPI using only free or cheap materials?

You can find plenty of free PDFs and YouTube lectures covering SPI, and that's genuinely enough to prepare for and pass the exam. That's because ultrasound physics is built on a fixed, already-established set of concepts — like grammar rules — so the material you need to study is the same no matter which source you use. Paying for a resource doesn't get you different or better content for SPI the way it might for Breast or Abdomen, where the material is broader and more detailed, and paid resources can genuinely be higher quality.

Can I pass without understanding Physics concepts, just memorizing question patterns?

You can pass by repeatedly solving practice questions without formally studying the underlying physics concepts first — but it depends on your learning type, the same way note-taking versus practice does. If you learn best by doing, picking things up through trial and error works fine for you. If you're a concept-first learner who needs to fully understand one idea before moving on, skipping concept study to just memorize question patterns isn't a good fit for you.

Does the real SPI exam look like Penny book / URR questions, or completely different?

All SPI prep materials — Penny book, URR, or anything else — are predicted questions, not pulled from the real ARDMS exam bank. Whether a specific book "matches" the real test more or less closely isn't really the right thing to evaluate.
