The CBT System is a Java Desktop Application designed by the integration of Java and MySQL to help provide a flexible platforms where by Computer Based Tests can be organized and performed. The System is divided into two parts, the UTME/JAMB CBT and the SCHOOL CBT. UTME in Nigeria stands for Unified Tertiary Matriculation Examination, formerly known as Joint Admission and Matriculation Board, an examining body which organizes tertiary matriculation examinations for prospective undergraduates. In recent years, the examining body decided to cede the paper based test for online computer based tests. On the introduction of this new platform, many examinees faced the daunting task of adapting to this new method, because they have not been used to CBTs and a good number of them also not being computer literates. This explains the motive behind the first part of the CBT System which was mainly designed to be a replica of the Original Online system in use and dedicated to helping aspiring examinees have first hand practice experience before time. The System is launched with three (3) already preinstalled examination packs, each scheduled for 3hrs:45 minutes. The SCHOOL CBT is designed for institutions with the desire to constantly set up CBTs for their students. This section of the system offers the flexibility of setting the examination parameter and indicating which student or class can take part in the exam. Special features such as withholding and releasing student’s results were also added
