SPI · Study Resources

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.

SPI · Study Time

How many weeks or months does it usually take to pass SPI?

Two different timelines for two different situations. If you can study full-time with no other obligations, the timeline really comes down to how intensively you work — some of my own students passed within two weeks, and quite a few passed with strong scores within a month. If you're working, raising kids, or juggling other responsibilities, plan for roughly 3 months if this is your first time preparing for SPI.

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.

2 weeks left before the exam — what should I focus on?

With two weeks left, the essential task is separating what you're solidly confident on from what you're not. Concepts you already know well at this point won't fade even without more review, so there's no need to keep re-studying them. Your remaining time should go almost entirely into the material you know only vaguely or don't know at all — use the Content Outline again to sort that out, item by item.

Are there many calculation problems in SPI Physics, or mostly concept questions?

You can only bring paper and a pen into the exam room, not a calculator. That alone tells you the math involved can't require one — what you'll see is simple hand-arithmetic (basic multiplication and division), barely more than that. A couple of harder calculation questions can show up as exceptions, but the overall share of calculation-based questions is small, and even those tend to be simple enough to work out by eye.

Worried nervousness will make me get even known questions wrong on exam day — any way to handle it?

Being nervous on exam day is unavoidable — and the real fix isn't eliminating the anxiety, it's using a time-management strategy that builds in enough margin to review everything two or three times. Exam-day nerves are normal, and they tend to grow the harder and more seriously you've studied — so don't spend energy worrying about feeling anxious itself. What actually helps during the exam is a full-review strategy: budget your time so you can go through every question, start to finish, at least twice — ideally up to three times.

How should I handle a question I don't know on the exam?

In my experience, roughly 10% of questions on the actual exam come from topics you've genuinely never studied, no matter how thoroughly you prepared — just knowing that in advance makes it less unsettling when it happens. For a question that's completely unfamiliar, guess immediately and move on: with four answer choices, your odds are about 25% whether you spend one second or one hour deciding, so there's no benefit to lingering.

Abdomen · Study Resources

Which study material is best for Abdomen — MUT, URR, or Penny?

For Abdomen, the three materials candidates ask about most are MUT (My Ultrasound Tutor), URR, and the Penny book. They do differ — in structure, depth, and how the material is presented — but none of those differences is decisive enough to make or break your exam result on its own. Whichever one you pick, the actual content you need to learn is largely the same, since abdominal ultrasound concepts don't change depending on which book teaches them.

Abdomen · Study Time

How many weeks or months does it usually take to pass Abdomen?

Abdomen requires more study time than other ARDMS subjects mainly because of scope, not difficulty. Breast focuses narrowly on breast anatomy and pathology, and Echo focuses on cardiac content — both have a fairly contained scope. Abdomen, despite its name, actually touches concepts across nearly the whole body, so the volume of material is roughly two to three times what Breast requires.

OB/GYN · Study Time

How many weeks or months does it usually take to pass OB/GYN? (Is 3 weeks possible?)

OB/GYN isn't really one subject, it's two: obstetrics (OB) and gynecology (GYN). Once you're actually studying, you feel it — it's about two subjects' worth of material — so build your study plan around that from the start. For specialty exams I generally recommend about 3 months on average, depending on your baseline. For OB/GYN, add roughly a month and plan for around 4.
