The document describes an online examination system that allows various certificate and non-certificate exams to be conducted and processed at different centers across countries via the internet. It allows students to take exams at any available center of their choice and gives companies and institutions a way to evaluate outstanding exam takers across a country. The system was developed using PHP and MySQL and has features for students to take exams, view results, and change passwords, for teachers to set questions, specify answers, and view marks, and for administrators to create/delete accounts and change student marks. It discusses the advantages, technologies used, constraints, and addresses bottlenecks of existing paper-based systems such as reduced paperwork and easier reviewing.
