✅ Detailed results review with manual grading
✅ Profile management with photo upload
✅ Export results/codes to CSV
✅ Real-time Firebase synchronization
2. Student Exam Interface
Key Features:
✅ Secure one-time access code validation
✅ 5 question types with dynamic rendering
✅ Dual timer system (per-question / full exam)
✅ Advanced anti-cheat (tab detection, devtools blocking, fullscreen enforcement)
✅ Camera proctoring with periodic snapshots
✅ Animated progress tracking
✅ Auto-submit on timeout
✅ Violation detection with instant termination
✅ Smooth fade animations between screens
Implementation:
Phase 1: Firebase Setup
Initialize Realtime Database with data structure (admins, questions, results, codes, settings)
Real-time listeners for live updates
Async data loading with error handling
Phase 2: Admin Dashboard
Login authentication system
Dynamic question form based on type
Image upload with base64 encoding (5MB limit)
Statistics calculation with animated counters

Camera permission & snapshot capture (JPEG compressed)
Phase 4: Anti-Cheat System
javascriptDetections:
- Tab switching (visibilitychange)
- Window blur/focus loss
- Screen resize/split detection
- DevTools detection (window size differential)
- Keyboard blocking (F12, Ctrl+C/V/X/A/P/S/U)
- Right-click & copy/paste prevention
```
**Phase 5: Results Processing**
- Score calculation
- Answer history storage
- Violation logging
- Snapshot upload to Firebase
- Completion screen display

## **Technologies:**
**Frontend:** HTML5 • CSS3 (Animations, Grid, Flexbox) • JavaScript ES6+
**Backend:** Firebase Realtime Database • Firebase SDK v10.7.1
**Security:** One-time codes • Camera proctoring • Anti-cheat detection
**Data Structure:**
```
Firebase:
├── admins/ (name, username, password, role, photo)
├── questions/ (type, text, choices, timeout, image)
├── results/ (score, answers, violations, snapshots)
├── accessCodes/ (used, usedBy, usedAt)
├── examSettings/ (timer, antiCheat, camera)
└── quizState/ (isActive)
Key Features:
? Real-time Sync - Live updates across all sessions
? Dual Timer Modes - Per-question OR full exam
? Smart Matching - Randomized options

Workflow:
Admin: Login → Create questions → Configure settings → Generate codes → Open exam → Monitor results → Review answers → Export data
Student: Enter code → Camera permission → Answer questions → Timer countdown → Auto-submit → Results uploaded
Deliverables:
✅ 2 HTML files (Admin + Student)
✅ Firebase real-time integration
✅ 5 question types with dynamic forms
✅ Anti-cheat mechanism
✅ Camera proctoring system
✅ Results export (CSV)
✅ Responsive design
✅ Production-ready code
