NEW! SANS ABNS Primary Exam Preparation

Residents can get on the path to success with the CNS SANS ABNS Primary Board Examination Review 4, a preparation exam composed of 900 preparatory neurosurgical questions. You can also access part one, two and three or get all four in the bundle. If you have previously purchased the bundle, Exam Review 4 is included and your residents should have access now. 

The CNS, your go-to resource for Primary Board Examination preparation, is proud to announce the second installment of the 4-part series of 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 course, 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.
