Built for Active Learning, Not Just Passive Review

The Radiology Core QBank is designed for residents who want to do more than answer questions and move on. In addition to tutor and quiz modes, the app includes an integrated active learning workflow that lets you highlight key passages, create rich-text notes, and build personalized flashcards directly from the material you are reviewing.

Multiple Study Modes: Use Tutor Mode for immediate feedback with detailed explanations, or switch to Quiz Mode for timed or untimed exam-style sessions.

Highlights directly from explanations and summaries: Select important text while reviewing high-yield content and save it as a highlight for later review. This makes it easier to focus on the exact rules, definitions, and teaching points you do not want to forget.

Rich-text notes tied to what you are studying: Save personal notes while reviewing NIS and RISC content instead of keeping scattered reminders in separate apps. Notes support formatting and can preserve source context when needed, making last-minute review more efficient.

Flashcards created from selected content: Turn key passages into editable flashcards with separate front and back fields. This makes it easy to convert explanations, summaries, and high-yield facts into a personalized review deck built around your weak points.

Spaced repetition review: Flashcards are designed for repeated review over time rather than one-time memorization, helping you revisit difficult material in a more structured way as exam day approaches.

Searchable study tools: Your saved flashcards and study material can be searched when you need a focused refresher before a quiz block, conference, or exam review session.

Advanced progress tracking: Monitor performance, track completed chapters, and identify weaker areas with detailed statistics so you can use your study time more efficiently.

Turn Explanations Into Review Material in Seconds

One of the most useful parts of the Radiology Core QBank is that study tools are built directly into the learning workflow. Instead of copying text into a separate notes app or trying to remember which explanation contained an important rule, you can work directly inside the app while the content is still fresh.

Select a key passage from an explanation or summary, then choose how you want to use it. You can highlight it for later review, save it as a note, or convert it into a flashcard that can be edited and reviewed again over time. This makes it easier to turn passive reading into active recall and spaced repetition without interrupting your study session.

For radiology residents preparing for the ABR Core Exam, that matters. NIS and RISC often contain dense factual material, edge-case rules, and easy-to-miss details that benefit from repeated exposure. Built-in highlights, notes, and flashcards help you capture those details while you are studying instead of hoping you remember them later.

Frequently Asked Questions

Is the content aligned with the latest ABR study guides?

Yes. The question bank is developed in strict alignment with the most recent American Board of Radiology (ABR) study guides. We update the question bank annually to reflect the most recent changes to ensure you are studying the right material.

What is the difference between Tutor Mode and Quiz Mode?

Tutor Mode is designed for active learning. It shows you the correct answer and a detailed explanation immediately after you answer a question. Quiz Mode simulates a real exam environment, allowing you to answer a block of questions in timed or untimed format and review your results and explanations at the end.

Do you offer discounts for residency programs?

Yes. We highly encourage programs to provide this resource for their residents. For department-wide access, our Institutional Access plan grants access automatically based on your hospital email domain. For smaller study groups, you can use our Group Purchases to get up to 50% off.

Does my subscription work across multiple devices?

Yes. Your subscription is linked to your Apple ID on iOS or your Google Play account on Android. You can seamlessly switch between your phone and your tablet, and your progress and statistics will be maintained.

How detailed is the progress tracking?

The app features an advanced progress tracker designed to help you study smarter. It provides detailed statistics on your overall accuracy, logs your best scores, and tracks your completed chapters. This visual breakdown makes it easier to identify weaker areas and focus your study time where it is needed most before the CORE exam.

Can I mark difficult questions to review later?

Yes. During any Quiz or Tutor session, you can bookmark specific questions that you find challenging. These saved questions are stored in a dedicated review section, making it easy to return to them without digging through the entire QBank.

Will my study progress sync across my devices?

Yes. Your study data, including your statistics, completed quizzes, and bookmarked questions, is tied to your user account in the cloud. As long as you are logged in, your progress can sync across your iPhone, iPad, or Android devices so you can continue studying where you left off.

How do I report an issue or give feedback on a question?

If you spot a typo or want clarification on a specific question while studying, simply shake your phone to open the interactive feedback tool and send a message directly to our editorial team.

Can I create flashcards directly from the material I am studying?

Yes. You can create personalized flashcards directly from content you are reviewing in the app rather than building a separate deck from scratch. Flashcards are editable, making it easy to refine both sides of each card to match your own study style.

Can I highlight text inside explanations and summaries?

Yes. The app allows you to highlight important passages while reviewing explanations and chapter summaries, which is useful for marking high-yield facts, definitions, and rules that you want to revisit later.

Can I save personal notes while I study?

Yes. The app includes built-in note-taking tools so you can save your own high-yield reminders, tricky distinctions, and personal takeaways while reviewing NIS and RISC material. This helps keep your study notes tied closely to the content you are actually using.

Are flashcards just static cards, or can I review them over time?

Flashcards are designed for repeated review, giving you a more active way to revisit weaker areas over time instead of relying only on passive rereading.
