🎯 What This Workflow Does

Provides a complete end-to-end educational experience through simple WhatsApp commands:

• 📝 Interactive Quiz Trigger Student sends a topic (e.g., quiz photosynthesis) via WATI Trigger to start a session.

• 🚦 Intelligent Command Routing A Route Message switch node detects specific student intents:

• quiz: Triggers the AI generation of new questions.

• answer: Routes to the evaluation engine to grade student replies.

• progress: Triggers the historical performance report branch.

• 👁️ AI-Powered Content Creation An AI Agent using GPT-4o generates 3 tailored MCQ questions based on the requested topic, formatted as structured JSON.

• 📊 Automated Grading & Logging

• Evaluation: Compares student replies (e.g., answer 1a 2b 3c) against stored correct answers fetched from Google Sheets.

• Logging: Saves the final score, topic, and date to the master database.

• 📈 Progress Visualization Fetches all historical scores to calculate average performance, identifies the "Best Topic," and generates a visual progress bar.

✨ Key Features

• Dynamic AI Tutoring: Quizzes are never repetitive; the AI generates fresh questions every time a topic is requested.
• Session Management: Uses a "Session Key" (Phone + Date) to ensure students can only take one specific quiz per day per topic.
• Visual Performance Feedback: Students receive formatted reports with emojis and visual bars (███░░) to track their improvement.
• Easy Answer Format: Simple shorthand for students (e.g., 1a 2b) makes it accessible for mobile-first learning.
• Centralized Database: All academic data is logged in Google Sheets, making it easy for teachers or parents to monitor results.

💼 Perfect For

• Students: Quick self-testing on subjects before exams or competitive tests.
• Teachers: Providing an automated "homework bot" for students to practice curriculum topics.
• Corporate Trainers: Deploying bite-sized knowledge checks to employees via mobile.
• Language Learners: Testing vocabulary or grammar rules on the go.

🚀 Quick Start

1. Import Template – Copy the JSON and import it into your n8n instance.
2. Set Credentials – Connect your WATI, OpenAI, and Google Sheets accounts.
3. Setup Spreadsheet – Create two sheets:

• Active Quizzes: Headers for sessionKey, phone, topic, correctAnswers, questionCount, today.
• Scores: Headers for date, phone, senderName, topic, score, total, percentage.

1. Start Learning – Send quiz solar system to your WhatsApp bot to begin!

🎨 Customization Options

• Question Count: Modify the AI prompt and code nodes to generate 5 or 10 questions instead of 3.
• Persona Tweak: Change the System Message in the AI Agent to make the tutor sound like a "Fun Scientist" or a "Strict Professor".
• Filtered Progress: Edit the Build Progress Report code to show reports for only the last 30 days.

🏆 Use Cases

Exam Preparation

A high school student uses the bot to drill on "Biology" and "History" topics daily, tracking their score increase over time via the progress command.

Employee Onboarding

A new hire receives a "Company Policy" quiz via WhatsApp; their score is automatically logged for HR compliance.

Community Education

An NGO uses the bot to teach health and safety protocols in rural areas where WhatsApp is the primary digital tool.

💡 Pro Tips

• Strict JSON: The AI Agent is prompted to return only JSON to ensure the workflow doesn't crash on conversational filler.
• Flexible Matching: The Build Progress Report node uses String() casting to ensure phone numbers match correctly even if formatted differently in Sheets.
• Topic Extraction: Use specific topics for best results; "Photosynthesis" works better than just "Biology".
