StudyBucky
Read full descriptionHide full description
StudyBucky is exam prep for the ARRT Radiography certification exam, built around the four ARRT content categories: Patient Care, Safety, Image Production, and Procedures. START WITH A DIAGNOSTIC A quick diagnostic, weighted across all four ARRT categories, shows you where you actually stand before you spend a single study hour. PRACTICE THAT TARGETS YOUR WEAK AREAS Adaptive practice pulls questions from the areas you keep missing. Filter by category, by lesson module, or let the app aim you at your weakest topics. FULL-LENGTH TIMED MOCK EXAMS Build a mock exam up to 230 questions, weighted to the ARRT blueprint and timed at one minute per question — the real exam's pace. Review every attempt by category and track your scores across mocks. ASK BUCKY, THE AI TUTOR Stuck on a question? Bucky walks you through the reasoning, then checks its own answer before showing it to you. When it cannot back something up, it tells you instead of guessing. GUIDED LEARNING PATHS Four ordered curricula — Image Production, Safety, Procedures, and Patient Care. Each module walks you through the lesson, drills you on it, then makes you clear a mastery check before it moves on. FLASHCARDS WITH SPACED REPETITION Save any question as a card and let the scheduler resurface it right before you would have forgotten it. Ready-made decks cover each learning path, plus focused decks on CR angles and common exam traps. INTERACTIVE DIAGRAMS Move a slider and watch the physics respond — inverse square law, grid ratio and cutoff, shape distortion, beam geometry, x-ray emission spectrum, photon interactions, tube construction, and a 3D foot and ankle model you can rotate. THE ARRT FORMULA SHEET Every formula, dose limit, and direction-of-change relationship you are expected to recall, on one page. Built for the last review before you walk in. QUESTION TYPES THAT MATCH THE REAL EXAM Multiple choice, select-all-that-apply, ordering, numeric entry, and image hotspot items — the same formats the ARRT exam uses. STUDY REMINDERS Enter the date of your exam and the app sends a native reminder the day before it. It also nudges you when your flashcards come due, so the spaced-repetition schedule actually happens instead of quietly lapsing. Reminders can be turned off in your device settings at any time. TRACK YOUR READINESS A readiness score, accuracy broken out by ARRT category, a study streak, and a Question of the Day to keep you honest between sessions. WRITTEN FOR ACCURACY Every question is researched, written, and independently checked before it ships. No recalled, leaked, or secured exam items are used, ever.
