Diploma Viva Question Bank Android App with Branch-Wise Questions and Offline PDFs

Diploma external vivas are examined by an outside examiner who probes fundamentals aloud — and students usually prepare from scattered sources: senior-shared notes, photocopied question lists and random online PDFs of mixed quality. There is no single place to revise branch-wise questions with short, speakable model answers, and most material needs internet, which is unreliable in college labs, hostels and exam halls. This project builds a native Android app that fixes exactly that: curated viva question banks organised by diploma branch, each question carrying a concise model answer written in viva-answer style. Full-text search works across all branches, bookmarks build a personal revision list of weak questions stored on the device, and every branch bank ships as an offline PDF generated from the same content source — so the PDFs always match the app. A tactics screen adds examiner-tested answering habits for the viva day itself.

1. The app launches and loads the bundled question content (a structured per-branch file of question, model answer, difficulty and topic tag) into memory — no server call.
2. The student picks their branch from the home grid (Computer, E&TC, Mechanical, Electrical, Civil or IT).
3. The branch screen lists its questions; a filter box narrows them by keyword, and difficulty/topic tags help prioritise.
4. Tapping a question expands its model answer — a short, speakable explanation written for viva delivery.
5. The student bookmarks questions they fumble; bookmarks persist on the device and appear under Bookmarks.
6. From the Offline PDFs screen, the student opens or downloads the branch's question-set PDF — generated from the same content file, so wording matches the app.
7. The Viva Tips screen gives answering tactics for the viva day itself.

Tech stack:

• Kotlin · Android SDK
• Android Studio · Gradle build
• Room · on-device storage (bookmarks, no cloud)
• JSON content bundle (branch-wise questions)
• PDF generation from the same content source
• Material Design components
• Git

• [Branch-wise question banks] Six diploma branches covered — Computer, E&TC, Mechanical, Electrical, Civil and IT — with curated MSBTE-syllabus-aligned viva questions per branch, expandable by adding to the content file.
• [Concise model answers] Every question has a 2–4 sentence model answer written for speaking, not reading — tap to reveal, covering the definition or law an examiner expects first.
• [Full-text search] Search across all branches from the home screen, or filter within a single branch by keyword — results show the branch tag so the student knows the context.
• [Bookmarks & revision list] Star weak questions; they collect into a personal revision list persisted on the device, available offline for last-night revision.
• [Offline PDF question sets] Each branch bank is generated as a printable PDF from the same content source as the app, so the two can never disagree — designed for no-internet revision.
• [Difficulty & topic tags] Every question carries an Easy/Medium/Hard marker and a topic label (e.g. Networking, Thermo), so students can target weak areas deliberately.
• [Viva-day tactics screen] Built-in answering tactics — draw first, define before deriving, admit limits honestly — drawn from how diploma external vivas are actually conducted.
• [Local-first, no-account design] No backend, no login, no internet needed for any core function; bookmarks and content live entirely on the device.

• Complete Android app source code (Kotlin, layouts, resources)
• Structured question-content file with sample questions for all six branches
• Six branch-wise offline PDF question sets generated from the same content
• Build instructions (Android Studio setup, APK generation)
• Project report PDF (background, methodology, architecture, outcomes)
• PPT presentation for final review
• Viva Q&A preparation document (Android concepts, content design, offline architecture)
