Clearly explain the existing problem and how your system solves it. For example: “Currently, [existing process] is done manually/inefficiently, which leads to [specific problems]. Our system automates this by [solution], which results in [specific benefits].”
3. Why did you choose this technology/framework?

6. What are the future enhancements of your project?
List 3 to 5 realistic improvements. “In future, we plan to add [feature 1], integrate [technology 2], and improve [aspect 3]. We also plan to deploy the application on [cloud platform] to make it accessible to real users.”

Tips for a Successful Viva
Know your own code: Never include code in your project that you cannot explain. Evaluators will ask about specific functions and you must be able to explain them.
Be honest about limitations: Pretending your project is perfect will backfire. Evaluators respect students who acknowledge limitations and suggest future improvements.
Practice live demo: Always run a live demo during your viva. A working demonstration is worth more than any explanation.
Prepare a one-minute summary: Be ready to explain your entire project in 60 seconds. This is often the first thing you are asked.
Dress professionally: First impressions matter. Dress formally for your viva presentation.
