Singapore Part B Question Bank Platform

A modern, optimized web platform for Singapore Part B Bar Exam preparation with comprehensive question banks across all practice areas.

🚀 Performance Optimizations

Current vs Optimized Structure

Before (Current Issues):

• Main HTML file: 1.89MB (way too large!)
• All questions embedded in HTML
• No caching or lazy loading
• Duplicate data across files
• No build system

After (Optimized):

• Main HTML file: ~50KB (96% reduction!)
• Lazy loading of question data
• Browser caching with localStorage
• Consolidated JSON structure
• Production build system

Key Optimizations Implemented

1. Lazy Loading: Questions only load when user selects a topic
2. Browser Caching: localStorage caches question data for 24 hours
3. Memory Caching: In-memory cache for instant subsequent loads
4. Critical CSS: Inline critical styles, async load non-critical
5. Minified Assets: Production build minifies all assets
6. Progressive Loading: Loading states and error handling
7. Responsive Design: Optimized for all device sizes

Recommended Server Configuration

# Cache static assets
location ~* \.(json|css|js)$ {
    expires 1y;
    add_header Cache-Control "public, immutable";
}

# Cache HTML with shorter expiry
location ~* \.html$ {
    expires 1h;
    add_header Cache-Control "public";
}
