  • SANS ABNS Primary Exam Preparation

    The CNS, your go-to resource for Primary Board Examination preparation, is proud to offer the CNS SANS ABNS Primary Board Examination Review. The ABNS has graciously agreed to allow the CNS to use question stems from the ABNS primary exam question bank in connection with this product, in recognition that the full question bank covers the breadth of what neurosurgeons are expected to master prior to commencement of their chief resident year.
