DESIGN AND IMPLEMENTATION OF AN ONLINE OBJECTIVE TEST
Computers are known for their wide range of uses especially in scientific and mathematical fields. However little or no thought has been given to designing a complete and through intelligence test on a computer system in out immediate environment. Although in advanced countries, where computerized games have been developed, computers have proved that they constitute of ways of indirectly testing intelligence. This system is designed in order to implement intelligence test on a computer system. It tries as much as possible to incorporate the important aspect of intelligence on a wide scale. It is designed to test intelligence of secondary school leavers using the Senior School Certificate Examination (SSCE) and the University Matriculation Examination (UME) as a standardized sample, and as such the Psychological implication of such a design is very important. The design of the system is quite simple and easily understood. Its flexibility makes it amenable for future changes and amendment to either incorporate other aspects of intelligence or to be designed for any other school age or class. The question of the intelligence test are programmed and visually displayed on the system’s screen in an interactive form. The student answers the question on the computer system. The results obtained from the test give an estimate on user’s (student) intelligence quotient (IQ). This is equally displayed and tells the student in what category he/she falls within. The result of the test is also displayed of the end of the test which goes a long way to lesson the fears of students that they were marked down in the examination.
ORGANISATION OF WORK

BACKGROUND OF STUDY:
In the past, ability tests were used in admitting students into University and professional schools, for instance the scholastic aptitude test, which measure, both aptitude and achievement, (the aptitude test measures accomplished skills & indicate what a person can do at present, while the achievements test predicts what a person can accomplished with training). But the essential requirements for any test include reliability, validity and uniform testing procedure. The test which measure general intelligence ability are often called “Intelligence test”.
Intelligence test are usually designed and implemented for a group of people to access the nature and course of mental development, intellectual and non-intellectual personality differences associated with age, sex & facial membership, differences that might be attributed to hereditary or to environmental factors, differences among persons at different occupational levels and among their children, intellectual and others traits of a typical group such as the mentally gifted, the mentally retorted, the neurotic and the psychotic.
The topic computer based intelligence test system (C.B.T.S) is geared towards impacting Intelligence on a computer, whereby the Universities Matriculation Examination (UME) and the senior secondary Certificate Examination (SSCE) will be conducted and taken on the computer system itself and the result displayed to the user (student) immediately after the examination. One may ask this question, is the realistic on the face value it might seem impossible, but with the advent of computer games, computers have proved that they constitute of ways of indirectly testing intelligence.
1.1 STATEMENT OF THE PROBLEM
A critical look at the operations of the west African Examination council, the organization of (SSCE) show that a part of their examination comes as an objectives questions and the answers are expected to be shaded on a computer answer sheets and marked by the computer, where as the theory section of the examination, which of course carries the greatest mark, is to be marked by WAEC examiners, leaving much to be desired especially in the Nigerian context of it.
Move so, in admitting students into higher schools differences attributed to hereditary or to environmental factors, differences among persons at different occupation levels and among their children; and facial membership may lead to bias, instead of admitting qualified students, unqualified students may also be admitted.
1.2 AIMS AND OBJECTIVES
The prime objectives of this topic “computer based intelligence test system (C-BITS)” is to enhance the use and process of the test of intelligence and intelligence quotient (IQ)in individuals. This test enable an establishment to access the intelligence capabilities of individuals to be admitted into higher schools and in offering of Jobs in the labor institution.
The project aims at an improved situation where the UME and SSCE examination will be conducted and taken on the computer system itself. The use of the computer system to achieve this is our area of concentration.
1.3 PURPOSE OF THE STUDY
This work is designed for solely accessing the intelligence capabilities and intelligence quotient of secondary school leavers.
Its purpose are to have the following:
(i) Efficient safe storage
(ii) Quick retrieval of records and information
(iii) Proper accounting and file keeping
(iv) Quick response to any adhoc enquires
(v) Assist in result recording
(vi) Assist in CCPA updating
1.4 SIGNIFICANCE OF THE STUDY
It is hoped that the result of this study will serve as tools for helping students who wish to take examination, and will go a long way helping the staff also. This is easy to achieve since standard and tested computer programs handle all sort of complex calculations, storage and retrieval of valuable information needed for the school. Also, important is the fact that records prepared with electronic machine can be stored as long as needed in non-bulky and compact systems.
1.5 THE SCOPE/DELIMITATION
The scope of this work is to outline the practical uses of the computer system in the area of intelligence test (IT), mental abilities and their measurements, computer assisted learning (CAL), the nature of intelligence and scholastic aptitude test (SAT).
Due to time constraint we were unable to extend our research to cover other subject, that was why we limited it to just four subject.
1.7 DEFINITION OF FORMS:
INTELLIGENCE: The power of learning, understanding seeing and knowing.
CHRONOLOGICAL AGE (CA): The actual age of a parent.
MENTAL AGE (MA): Is the person level of understanding measured is terms of the average age of children having the same standard.
FLOPPY DISKETTE: Is a this plastic located with an aperture that allows a rend /write head to access the diskette
VISUAL DISPLAY UNIT: Is the screen in form of (TV) Television component. Both input and output are displayed there.
INTELLIGENCE QUOTIENT: Express the measure of mental age (MA) to chronological age (CA).
