The Online Examination System is a comprehensive web-based application developed using PHP and MySQL to simplify and automate the examination process for schools, colleges, coaching institutes, training centers, and online learning platforms. The system replaces traditional paper-based examinations with a secure digital platform, allowing users to take exams anytime through an intuitive and user-friendly interface. Students can select their preferred subject or quiz category and begin their examination with a single click. Questions are presented individually, and each answer is submitted separately to ensure a smooth and reliable examination experience. After completing the exam, the system instantly evaluates the responses and generates detailed results, displaying the total score, correct answers, incorrect answers, and overall performance.

To encourage healthy competition, the application includes a leaderboard that showcases the highest-scoring participants along with their respective colleges or institutions. Users can compare their performance with others while tracking their own progress over multiple examinations.

The administrator panel provides complete control over the examination system through a centralized dashboard. Administrators can create and manage subjects, quiz categories, questions, answer options, and correct answers. They can also monitor the total number of exam participants, review examination statistics, and maintain complete exam records from a single interface.
