RadPrimer is a well-respected ACR product used widely in radiology training programs. For certain types of learning — especially imaging physics and case-based review — it offers genuine academic value. But for residents specifically targeting the ABR CORE exam, it has notable gaps: limited NIS coverage, a question format that doesn't match the CORE's scenario-based style, and analytics that aren't structured around CORE modules.
RadCore is the leading RadPrimer alternative for CORE-specific preparation. With 400+ NIS questions (the module where RadPrimer is weakest), 340+ RISC questions, and 760+ Physics questions in the ABR's exam format, RadCore covers the full CORE blueprint. Its mobile-first design and category-level analytics also make it more practical for the daily study habits that drive long-term retention.
