Chapter 1 : Introduction
1.1 Background of Study
• CBA is a test conducted using Personal Computer (PC) In which responses
are electronically recorded and assessed.
• CBA system supports the entire cycle of the evaluation process:
preparation, distribution, execution, submission, evaluation, delivery of
results, and filing.
• Computer Based Assessment (CBA) System is very useful for Educational
Institute to prepare an exam, save the time that will take to check the
paper and prepare mark sheets.
• Furthermore, Computer Based Assessment allows more innovative and
authentic assessments due to more advanced technological capacities.

1.2 Statement of Problem
• The challenges faced with TVET College or Training organizations is
their students adapted with Paper-Based Assessment and their
trainees subjected to a Computer Based Examination platform; in
which the performances of the trainees are reduced die to their
confusion with this new technology.
• The most adapted Paper Based Assessment is resource (materials,
energy, time,and human power) wastage.

1.3 Objectives of the study
• The aim of this project is to design and implement a computer based assessment system for Training
organizations with the following features.
• Provide user friendly
• Improve credibility of the exam by randomization of the questions.
• Provide real time processing of of results.
• Create strong and secret databases that allow for any connection in a secret way.
• Allow each department to create more than one exam with different way to create variant questions.

1.4 Scope of the Study
•The Study covered the design and implementation
of CBA with flexible features in our country
educational institutions or training organizations.
•System handles all the operations:
• Generate reports that include (name, mark, time spent
to solve the exam, and list of students by rank).
• Allows the students to see or display his/her answers
after the exam finished.

1.5 Limitation of system
• Limitation of the system to be designed are as follows:
• This system is designed for educational institutions (like school, universities,
college or training centers).
• Type of supported questions are multiple choices, true and false, free answer
and matching.
• The type of questions like working out, short answes and drawings are not
supported.

1.6 Significance of the study
• Reduce costs for many elements of testing life cycle.
• Provide more efficient system; reduce need of man power, reduce
lose of paper, reduce time and energy.
• Increased delivery, administration, and grading efficiency.
• Consistency and reliability.
• Faster decision making as the result of immediate grading and
reporting.
• Minimize Chance cheating on exam.
• Fewer errors caused by testing process.

Chapter 2 : Literature Review
2.1 Theoretical Background
• The technologies used in this system are web technologies:
• HTML
• CSS
• PHP
• JAVA SCRIPTS
• MYSQL

2.2 Review of Related Literatures
• Web-based Examination System is an effective solution for mass education evaluation (Zhenming et al,
2003). They developed a novel online examination system based on a Browser/Server framework which
carries out the examination and auto-grading for objective questions and operating questions, such as
programming, operating Microsoft Windows, editing Microsoft Word, Excel and PowerPoint, etc.
• It has been successfully applied to the distance evaluation of basic operating skills of computer
science, such as the course of computer skills in Universities and the nationwide examination for the high
school graduates in Zhejiang Province, China.

Chapter 3: System Analysis and Design
3.1 Introduction
• System Analysis is understanding of old system and determine how
Computer and software can be used to make operations effective.
• System Design is the process of preparing a prototype of new system
or one to replace existing system.
• System Analysis and Design relates to shaping organization improving
performance and achieving objectives for profitability and growth.

3.2 Methodology
• This study relied on information obtained from secondary sources especially online materials, documents of
relevant agencies. From these documents required information was obtained on the performance computer
based test in CCNA Certifications.
• The Object-Oriented Analysis and Design (OOAD) methodology was used during the software development.
• Unified Modelling Language (UML) notation is the design tool used for modelling in this research.UML used
in the research includes: Use Case diagrams, Data Flow diagrams and Class diagrams.

3.3 Analysis of Proposed System
• There will be a registration page where administrator/instructor would be able to register students.
• Once a student has login into the system, he/she would see list of availabletests.
• Before a student attempts to take an assessment, aOne-Time Passcode would be entered which is issued
by the instructor before the commencement of an exams.
• Eachassessment may consists of many questions containing many options , in which the system would
randomized the questions for differentstudents.
• At the end of the assessment, a student would be able to see his/her scores (results).

Chapter 4:System Implementation and Testing
• Introduction
• Hardware and Software Acquisition
• Hardware tools
• Server
• Client computer
• Network cable / connection
• Printer
• Software tools
• Server Database: -MySQL
• Wamp Server: Apache 2.4.35 Port 80- PHP 7.2.10

System implementation and Testing cont…
• Software Testing
• The unit testing approach was adopted in testing the codes written.
• Training
During the deployment of the system, the project development members will give short time training for the
system administrators and clerks explaining how the system works and in what way they can manage the
system developed.
• Installation
• Installation Steps:
• Download and install Wamp Server 3.1.4 compatible bit with your computer
• Place Website files inside “C://wamp/www/”
