+6. **Deploy** and enjoy your clean, unbranded app in light mode!
+
+**✅ Simplified Setup**: No configuration files needed - everything is embedded in the code!
+
+## 🔧 Key Assumptions Made
+
+### Technical Assumptions
+- **Internet Connection**: Required for AI question generation via Groq API
+- **Modern Browser**: Chrome, Firefox, Safari, or Edge for optimal experience
+- **JavaScript Enabled**: For interactive features and animations
+- **Screen Resolution**: Optimized for desktop (900x600+) but mobile-responsive
+
+### Educational Assumptions
+- **Grade-Level Mapping**: Questions are mapped to typical curriculum standards
+- **English Language**: All content is in English (future multilingual support planned)
+- **Basic Math Knowledge**: Students should have foundational knowledge for their selected grade
+- **Self-Assessment**: Students can honestly select their appropriate grade level
+
+### User Experience Assumptions
+- **Session-Based**: Progress is stored in browser session (no persistent accounts)
+- **Single User**: Designed for individual learning sessions
+- **Immediate Feedback**: Students benefit from instant question feedback
+- **Hint System**: Students will use hints constructively for learning
+
+## 💡 Design Choices Explained
+
+### Architecture Decisions
+
+#### **1. Streamlit Framework**
+- **Why**: Rapid development, built-in UI components, easy deployment
+- **Trade-off**: Less customization vs faster development
+- **Benefit**: Focus on educational content rather than web development
+
+#### **2. Groq API (Llama 3.3 70B)**
+- **Why**: Fast inference, high-quality question generation, cost-effective
+- **Alternative Considered**: OpenAI GPT-4 (more expensive, slower)
+- **Benefit**: Real-time question generation with excellent mathematical reasoning
+
+#### **3. Session State Management**
+- **Why**: Simple, no database required, immediate functionality
+- **Trade-off**: No persistence vs simplicity
+- **Future**: Will add database for user accounts and progress tracking
+
+### UI/UX Design Choices
+
+#### **4. Branding Removal**
+- **Why**: Professional appearance, focus on content, white-label experience
+- **Implementation**: Custom CSS + Streamlit config to hide all branding
+- **Benefit**: Clean interface that looks like a dedicated educational platform
+
+#### **5. Light Mode Only**
+- **Why**: Better readability for mathematical content, consistent experience
+- **Implementation**: Forced light theme via config and CSS overrides
+- **Benefit**: Optimal contrast for equations and diagrams
+
+#### **6. Card-Based Layout**
+- **Why**: Modern design, clear content separation, mobile-friendly
+- **Implementation**: Custom CSS with gradients and shadows
+- **Benefit**: Engaging visual hierarchy that guides attention
+
+### Educational Design Choices
+
+#### **7. Hint System**
+- **Why**: Scaffolded learning, reduces frustration, promotes understanding
+- **Implementation**: AI-generated hints for each question
+- **Benefit**: Students learn problem-solving strategies, not just answers
+
+#### **8. Multiple Difficulty Modes**
+- **Why**: Accommodates different learning styles and confidence levels
+- **Implementation**: Easy/Medium/Hard with different AI prompts
+- **Benefit**: Personalized challenge level for optimal learning zone
+
+#### **9. Progress Visualization**
+- **Why**: Motivates continued learning, shows improvement patterns
+- **Implementation**: Plotly charts with performance trends
+- **Benefit**: Data-driven insights into learning progress
