Six months of NBME Clinical Neurology Shelf Examination data was analyzed. The percentage of University of Minnesota medical students incorrectly answering questions within subtopics defined by NBME was compared to the national mean. The subtopics containing questions most often answered incorrectly by University of Minnesota students relative to national mean were “cerebrovascular disease,” "traumatic and mechanical disorders,” and “infectious disorders.” Interactive, case-based, online modules were developed to address these specific subtopics using Google Slides software. These modules are completed by clerkship students during a non-clinical week of didactics during the neurology clerkship.
