The document provides advice on various aspects of completing a PhD, including selecting a topic, writing a thesis, being a good PhD student and supervisor, and completing the viva. It recommends selecting a topic that addresses gaps in existing research and adds to the knowledge base. A good thesis introduces the problem well, demonstrates expertise, and shows how the problem was solved. Being a good PhD student requires intelligence, creativity, hard work, and endurance. A good supervisor provides guidance, timely feedback, and inspiration. Writing up takes longer than expected, so chapters should be reviewed early. Meeting deadlines is important to avoid graduation delays. The viva involves a presentation and questioning from examiners.
