Application Of Computer –based Examination System
[A CASE STUDY OF ABIA STATE POLYTECHNIC, ABA]

1.4.    SCOPE AND LIMITATION OF THE STUDY
SCOPE: The study is focused on the online and computer based examination system. The world we are living today is moving towards, I.C.T complaint and every aspect changes simultaneously. The research project is aimed on setting a standard for examination. This scope of area coverage includes the admission procedures of students who might have passed through Jamb. The entrance is to cover the necessary areas of admission, aptitude test which for long have been done manually. The scope also keeps the exams and record department at rest and less human resources needed since work is done automatically.
LIMITATION : This study could have been hinted free if not of most obstacles which also contributed to setting up standard. The researcher during the cause for the research work was faced with several challenges which are as follows:
a.    Time: The time factor posed a serious challenges for me since the research work was carried out within the academic period. The task of combining academic activities and the research work was tedious. It was not easy because most source of information gotten, I had to visit the school frequently.
b.    Finance: Financing involvement of the research work is another challenges to the success of this research work. The financial involvement coupled with academic financial activities and my personal needs as a student was insufficient. Hence, I had to work within the means of the finance availability.
c.    Unavailability Materials: Since the innovation of the online and computer- based exams is a new development in our society much has not been written about invention/development. I had to work and also spend much to get some of the materials. Most of the available ones are not really comprehensive hence it caused a serious challenges to the success of this research .
1.5.    STATEMENT OF THE PROBLEM
This section deals with the identification of the problem associated with current system. The management of examination records of the student over the year has been very poor, and errors on the results of students. Due to the manual system, it is no longer new thing that the students loss their results. The method of information storage is poor, this limits the number of official documents accessible by the students because the system is not capable of managing old items of information which could be use by student anytime. The other inherent problems of system includes.
a.    The problem    of time: The time for the release of the result is one of the crucial problems of manual system. The manual system takes time.
b.    The problem of inconsistency and accuracy: In the script of students, most time missing script becomes the main problem. The problem that gives rise to this, is the problem of space, the bulk of paper used for the exam occupies unimaginable large space.
c.    The problems of accessibility: It was observed that only the exams department
have access of using the results. Hence students find it hard to access their result easily.
d.    Impersonation: the existing system allow for someone to come and write examination for another person
