External examiners ask questions that internal guides never prepare you for. In MCA/BCA final year vivas, 60% of questions come from your actual code—not textbook theory.

What This Tool Checks

  • Analyzes your project code to predict likely questions
  • Generates questions at Easy, Medium, and Hard difficulty
  • Provides model answers you can study
  • Covers concepts, implementation logic, and design decisions
  • Works with Java, Python, JavaScript, and more
  • Simulates real external examiner questioning patterns

Who Should Use This Tool

  • Final year MCA/BCA/BTech students before project viva
  • Students whose guide isn't preparing them adequately
  • Anyone panicking before external examination
  • Students who wrote code but don't fully understand it
  • Groups where one member wrote most of the code

Common Mistakes to Avoid

  • ✕Only preparing theoretical questions, ignoring code-specific ones
  • ✕Not being able to explain your own project's database schema
  • ✕Can't answer 'Why did you choose this [technology/approach]?'
  • ✕Not knowing basic syntax/concepts of the language you used
  • ✕Unable to explain the flow from frontend to backend to database

Frequently Asked Questions

This tool helps you understand purchased or borrowed projects. Paste the code, study the generated questions and answers, and you'll be able to explain it confidently in viva.
Not exactly, but they cover the patterns external examiners typically follow. Examiners ask about your specific implementation, design choices, and underlying concepts—which is what this tool targets.
Focus on your main logic files—your primary controller, service layer, or algorithm implementation. Don't paste boilerplate or configuration files. 200-500 lines of meaningful code works best.
Start with Medium to understand your gaps. If that feels easy, move to Hard. Easy mode is good for last-minute revision. External examiners typically ask Easy to Medium level for average students, Hard for toppers.
