Never wonder what to study next
Thirty-two plain-English lessons across all four ARRT® content categories, in the order that actually builds on itself — each one ending in a quiz that checks you understood it.
A question bank doesn't teach you anything
Most prep is a pile of questions and a score. When you miss one you find out you were wrong, not why — and nothing tells you which concept to go learn, or what has to come first. So you drill randomly and hope the gaps close.
Four paths, thirty-two lessons, one order
Image Production, Radiation Safety, Procedures, and Patient Care each get their own path. Inside a path the lessons run in dependency order — you learn what a photon interaction is before you're asked to reason about attenuation — and your place is saved as you go.

Each lesson ends in a mastery quiz before the next one unlocks.
How a lesson path works
Pick a category
Or start where your diagnostic says you're weakest.
Work the lessons in order
Short, plain English, with the concept explained before the exam trick.
Prove it with a mastery quiz
Each lesson ends in a check, so you find the gap now instead of on test day.
What you get
Every lesson is written against the ARRT® exam content specifications and checked line by line against the reference textbooks we ingest — the same source Ask Bucky cites and the same source the question bank is built from. When the textbooks disagree with each other, the lesson says so rather than picking one quietly.
Questions
Do I have to follow the paths in order?
No. The order is the recommendation, not a lock — you can jump to any lesson in any path at any time. It's there so you always have an answer to "what next" if you want one.
How long is a lesson?
Short enough to finish in one sitting. They're written to cover a single concept properly rather than to hit a word count, so length varies with the topic.
Is this just the questions with extra text around them?
No — the lessons teach the concept first, and the practice questions are a separate surface. Each lesson does end in a mastery quiz drawn from the question bank so you can check the concept landed.
Can I read the lessons before I subscribe?
You can browse the paths and lesson pages without an account. Scored actions like the mastery quizzes are what require a plan.
