Not another PDF and a question bank. A course built around how you learn — and honest about where you get stuck.
Video lessons, interactive charts & simulators, flashcards, and full practice questions — watch, do, and read.
Real face time every week with a respected dental radiography educator. Come with questions, leave with answers.
Missed questions are tracked automatically and rebuilt into their own review deck.
Practice weighted exactly like test day — 50 / 25 / 25 across the three domains.
Your welcome from Indigo — what this course is, how it works, and exactly where to start.
The RHS exam is 75 computer-based questions in 60 minutes, scored on DANB's 100–900 scale — 400 passes. It covers work you'll actually do every day, in three well-defined domains. There's no trick here: understand the machine, the technique, and the safety rules, and the questions read like things you already know. That's exactly what this course builds.
Half the exam lives in Domain I — how a diagnostic image actually gets made. The other half splits evenly between radiation safety and infection control, the two topics self-studiers skim. We spend your time where the points are.
None of this is on the test to trip you up — knowing it ahead of time is half the battle.
If you have a documented disability — including a learning disability like dyslexia or ADHD, not just physical conditions — you have the legal right under the Americans with Disabilities Act (ADA) to request testing accommodations. This isn't "cheating" or a shortcut; it's making sure the test measures what you know, not the effect of a disability. The passing score stays exactly the same — only the testing conditions change.
Commonly up to 50% more — a 60-minute exam becomes 90.
A separate, low-distraction testing room to yourself.
Additional break time built into your testing session.
Bigger text if reading standard print is a barrier.
Someone to read questions aloud or record your answers.
Permission to bring medication or a medical device (e.g., to monitor blood sugar).
Under the ADA, this covers any physical or mental impairment that substantially limits a major life activity — including learning, reading, concentrating, or thinking. You may qualify even if you've never formally requested accommodations before. What matters is current documentation of your condition and need.
Get a letter or report from your doctor, psychologist, or school documenting your disability and why you need the accommodation. If you've had accommodations before, include proof — it helps.
DANB administers the exam through Pearson VUE. Request your accommodation as part of registration, before you book a test date — it can't be added to an appointment you've already scheduled.
Reviews can take 2–4 weeks, per DANB. You'll get a decision in writing; if approved, it includes instructions for scheduling with your accommodation applied. If denied, you can ask why and appeal.
Begin on DANB's exam accommodations page (danb.org) and the Pearson VUE accommodations portal — DANB's testing partner handles the requests. Your medical information is kept confidential and used only to evaluate your request. When in doubt, contact DANB directly and ask — they'll walk you through the exact current steps.
This is general guidance to point you in the right direction — exact forms, timelines, and requirements are set by DANB and Pearson VUE and can change, so always confirm the current process with them directly.
Every concept follows the same arc that actually makes things stick — understand it, drill it, then simulate the real exam.
Short video lessons, plain-English analogies, and hands-on visuals until the idea genuinely clicks — not memorized, understood.
Retrieval practice with feedback that explains why the tempting wrong answer is wrong — where real learning happens.
A timed, full-length mock exam weighted like the real blueprint, so test day feels familiar, not frightening.
24 lessons — with 26 lesson videos, interactive walkthroughs, and drills — organized exactly like the exam blueprint. Tap any lesson to jump in.
Learning is only half of it. The 26 lesson videos teach it — these turn "I think I know it" into "I've done it a hundred times."
A full 75-question, 60-minute simulation weighted 50/25/25 like the real blueprint, with no feedback mid-test and a per-domain breakdown at the end.
Diagnose the error, name the landmark, make the accept-or-retake call — then see exactly why the tempting wrong answer was wrong.
Every must-know term, color-coded by domain, built for keyboard-fast review.
Every score, every trend, every missed question in one place — so you know exactly when you're ready to book the real thing.
Start with the first lesson today. No cramming — just one clear idea at a time, until the whole exam feels like something you already know.
