Reread your thesis. On a sheet of paper, write a few sentences for each chapter to highlight key points and summarize the chapter. Write down and memorize a few page numbers where you have made significant points.
Write down potential questions that the panel may ask you. Make the questions hard and easy. The questions can be probing, open, closed, general or specific. Also write down a 2-minute response to each question.
Prepare to speak longer and elaborate on these questions. Use examples in your answers and practice going from general concepts to specific examples. Work into your responses the page numbers you memorized containing highlights of your thesis.
Have at your fingertips the names of key people that you have studied and researched while writing your thesis. Remember the references cited in your thesis. Memorize dates, books and journal titles to support and give validity to your responses.
Set up a practice viva session with your supervisor, several colleagues and, if possible, others who have gone through the process. During the session, practice answering questions with thought, clarity and confidence. After the mock session, ask for feedback and suggestions.
Attend a colleague's defense if it is open to the public. Take notes; this will give you an idea of how the examination is conducted and help you prepare for your defense.
Organize and prepare any visual aids well in advance. If you plan to use visual aids, familiarize yourself with the setup and operation of the necessary equipment.
Find out who will be on the examination panel. Learn all you can about each examiner. Become familiar with their work and areas of interest. Look for ways to connect your work to theirs.
Get a good night's rest. Have a light meal a few hours before the examination. Present a positive impression with professional, yet conservative clothing. Review your notes. Take your thesis, paper and pencil with you to the examination room.
