2. What Is a Project Viva?
A viva (viva voce) is an oral examination in which examiners ask questions about your project’s concept, implementation, methodology, results, tools, technologies, and real-world applications. Viva checks whether the work in your report and presentation truly belongs to you and how well you understand it.
Purpose of Viva
| Purpose | Meaning |
|---|---|
| To check originality | Did you really understand your project? |
| To evaluate knowledge | How deeply do you know the topic? |
| To test thought process | Can you explain logically and clearly? |
| To assess implementation | Is the project real or copied? |
| To check confidence | How well do you speak and answer? |
3. Why Viva Is Important
Proves your technical skills
Helps examiners judge your understanding
Builds confidence for interviews
Improves communication and presentation skills
Helps convert academic knowledge into practical experience
A strong viva increases your project score and even helps during placements when companies ask similar questions.
