Since 1975, when the University of Oklahoma faculty created their review course for second-year medical students, the Oklahoma Notes have been among the most trusted and widely used reviews for the National Boards. Each Oklahoma Notes book presents the core information of one segment of the medical school curriculum. Written by some of the most effective medical educators in the country, and now thoroughly updated and revised, the Oklahoma Notes feature: Concise text presented in outline format for rapid review; contents oriented to promote Boards success; self-assessment questions geared to the current format of the USMLE exam; more tables and figures designed to facilitate self-assessment and review; and low-cost, complete coverage of all subjects taught in the first two years of medical school.
