+📊 Final Score: {score}% 
+✅ Correct Answers: {correct_count}/{total_attempted}
+
+🔧 System Status:
+{api_status}
+
+🚀 Key Improvements Made:
+• Fixed overly broad reversed text detection
+• Improved search result processing with structured data
+• Better answer box and knowledge graph utilization
+• Enhanced person/actor name extraction
+• Improved numerical and date extraction
+• More precise question classification
+• Eliminated generic "right" fallback answers
+
+📈 Technical Fixes:
+• Removed faulty 'fo' pattern that triggered false positives
+• Added proper search result structure handling
+• Implemented context-aware answer formatting
+• Better handling of edge cases and errors
+• Improved rate limiting and error recovery
+
+💡 Performance Notes:
+This version should show significantly better accuracy by properly processing search results and avoiding the classification errors that caused nonsensical answers in the previous version."""
