AOBOG has now officially adopted a time limited certification and changed the recertification process to Osteopathic Continuous Certification in Obstetrics & Gynecology (OCC). You will need to take and pass a written exam every six years. Our review course will give you all you need to pass with confidence, you can do it--we can help. If you're a great clinician, but a lousy or rusty written exam taker, you may want to consider our test taking skills workshop and other products. View course topics Try our practice test questions!
