Online AnswerSheet Checking System
Project Overview
- The Online AnswerSheet Checking System is a modern web-based application designed to digitize the entire examination evaluation process for universities and educational institutions.
- The system enables scanned answer sheets to be uploaded, distributed, evaluated, and reassessed online, replacing traditional manual paper checking with a secure, efficient, and transparent digital workflow.
- The platform significantly reduces evaluation time, improves accuracy, and ensures complete auditability of examination results.
Problem Statement
- Traditional examination evaluation systems face multiple challenges:
- Manual checking of physical answer sheets
- High risk of human error
- Time-consuming result declaration
- Difficulty in re-evaluation (reassessment)
- Poor tracking of answer sheets
- Lack of transparency and audit trails
- Universities needed a scalable digital solution to modernize examination assessment.
Objectives
- The main objectives of this system are:
- Digitize answer sheet evaluation
- Automate distribution of answer sheets to faculty
- Improve accuracy and consistency in marking
- Reduce result processing time
- Enable secure reassessment workflows
- Maintain complete examination records
