Built for Active Learning, Not Just Passive Review
Core QBank is designed for residents who want to do more than answer questions and move on. Alongside tutor and quiz modes, use highlights, rich-text notes, and personalized flashcards to turn the material you review into your own study resources.
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
Study tools are built directly into Core QBank. Instead of copying text into a separate notes app or trying to remember which explanation contained an important rule, work directly in the QBank 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.
