This paper presents an Online Examination System developed using the MERN stack (MongoDB, Express.js, React.js, and Node.js) to automate and simplify the examination process. Traditional examination methods are time-consuming and require manual effort for evaluation and result generation. The proposed system provides a web-based platform where students can attempt exams online and administrators can manage questions efficiently. The system automatically evaluates responses and generates instant results, reducing human errors and improving accuracy. The implementation demonstrates enhanced efficiency, reliability, and accessibility, making it suitable for modern digital education environments.
