Not every radiology question bank is designed for the ABR CORE exam. The best radiology question bank for residents should cover NIS, RISC, and Physics — the three domains the ABR actually tests — with up-to-date, explanation-rich questions that teach the reasoning behind every answer.
Four platforms dominate the space: the ABR's NIS QBank (free, NIS-only), BoardVitals (multi-specialty, general radiology), ACR RadPrimer (academic, physics-strong), and RadCore (purpose-built for CORE, all three modules). When evaluated on CORE-specific coverage, ABR alignment, explanation quality, analytics, and mobile accessibility, RadCore is consistently the top-rated option for residents specifically preparing for the ABR CORE exam.
The ideal approach for most residents: use RadCore as your primary platform for all three modules, supplement with the free NIS QBank for additional NIS practice, and use RadPrimer's physics content if you want an academic complement.
