This chapter explores the purpose of a Viva, with a particular emphasis on providing guidance to Ph.D. candidates on how to successfully complete it within the United States (U.S.) academic context. Using secondary literature sources, the chapter informs Ph.D. candidates about the Viva examination. It explains what a Viva is and why it is necessary, outlines the examination process and outcomes, provides practice and preparation strategies, presents frequently asked Viva questions, and delivers tips and encouragement to support candidates in successfully passing their Viva. The literature findings highlight that practice and preparation are key for success. Ph.D. candidates can enhance their readiness by managing their time effectively, having an in-depth knowledge of their doctoral thesis and their examiners' publications, practicing common Viva questions through Mock Viva sessions, and understanding how to manage anxiety before, during and after the examination. Knowing how to navigate the Viva process is essential, as it marks the final stage of the Ph.D. journey.
