Common Pitfalls (and How to Avoid Them)

1. Failing to Know Your Audience

❌ Using jargon and assuming examiners know your niche
✅ Offer a high-level overview, define terms concisely, keep the big picture in focus

2. Neglecting the Narrative

❌ Jumping between chapters without flow
✅ Structure as a story: Question → Method → Findings → Impact

3. Underestimating the Q&A Session

❌ Becoming defensive or evasive under pressure
✅ Anticipate difficult questions, rehearse clear answers, admit uncertainty where needed

4. Ignoring Feedback

❌ Treating the defense as the end of the process
✅ Take notes, listen carefully, and integrate examiner feedback into revisions

Flow of a Strong Defense Presentation

Start → Introduce research motivation 
      → Present research questions 
      → Literature gap and relevance 
      → Methodology & justification 
      → Results and discussion 
      → Impact and significance 
      → Reflection & future research 
      → Q&A → End
