This AI-powered agent simplifies the process by evaluating scanned student answer sheets intelligently and accurately.\n\n## Solution Overview\n\nTeachers only need to upload a scanned copy of the student’s answer sheet through the form. The AI agent—connected to the Question Paper and Correct Answer Sheet tools—automatically compares each answer, calculates marks, and generates results in JSON format.\n\nThe evaluated data is then saved into Google Sheets, but it can also be integrated with any school database for seamless record management.\n\n## Future Enhancements\n\nThis flow can be further enhanced to handle multi-page answer sheets and generate customized evaluation reports based on the school’s format or grading standards."
