The study is an online, computer aided tool that was designed primarily for the conduct of online examination. The system was created using PHP, a web based scripting language, and MySQL as the database software. The system focuses on the automation of students' examinations; preparation, scheduling, checking and grading. A database is provided for the storage of exam questions, answers to questions and students' records. The system allows instructors to create an exam by entering questions with its corresponding answers into the database. Instructors are provided with three options on the type of exam; these include, True or False, Multiple Choice and Fill in the Blanks.There are three account types based on the intended users. One is the Administrator Account; this can be used to create instructor accounts. It can also be used to delete or suspend other accounts based on activity status. The Instructor Account allows teachers to create student accounts and enroll the same. This account can be used also to create, activate, edit, delete exams and monitor students' performances. The Student Account is for the officially enrolled students where they can take exams and view scores even from previous examinations.This software allows instructors to keep track of students' performances from all exams since the results will be stored in a database linked to an online system. While taking the online exam, students can choose the number of exam questions that will be displayed on the screen at a given time.A student can take the exam only on the specified date and time set by the instructor. Ideally, a particular exam should be taken only once. In cases of retakes due to valid reasons and special exam considerations, the instructor is given the option to administer the previously activated exam, edit or create a new set of questions.One limitation though, this online system is not to be used to compute for the class performance for the final grade since this requires other components such as seat works, graded recitations, laboratory activities, etc. This only computes and shows the scores from previous exams and the average.
