ABSTRACT

Online live examination system is a software solution, which allows a particular institute to

arrange, conduct and manage examinations via an online environment. This can be done

through the Internet, Intranet and/or Local Area Network environment. To bring the live

monitoring feature was the key challenge to accumulate into the system.

To develop the system several articles and journals of different researchers and university

was read. To gain the more appropriate knowledge several existing application around the

world was viewed. We did not find in our review such distinct feature where system can

simultaneously serves the purpose of exam process and result progress.

To design and develop it was intend to follow the software development life cycle (SDLC)

which is a conceptual model used in project management that describes the stages involved

in an information system development project. The MVC software architecture pattern was

follow to gain the user interface and activity flow thus it would be maintained international

standards and become a robust system. The MVC pattern also helps to maintain the code for

further modification.

To develop the system HTML, PHP and JavaScript is used to achieve the project. MySQL

Server is used as database management system. Apache web server is used to host the

application. The system can run both Windows and Unix environment.

Online live examination system is the way of improving examination activities fast and

efficient. This software is interactive and user friendly has all the command controls that

would allow student successfully accomplish the exams have been implemented using the

simplest graphic styles. The live monitoring features enable this application a distinct

attribute from other existing application.

CHAPTER 1: INTRODUCTION 1.1 Introduction

Examination is one of the best method of evaluating the knowledge and ability of an

individual. In the age of present information technology, online based examination has been

highly interested and suitable in both educational and pedagogical aspects. It can be used in

place of manual or paper method which was characterized by massive flaws like examination

leakages, impersonations and invigilators of examinations.

In this project students can participate into examination from remote location and get their

results instantly after finishing the exam. To participate into the exam they should have

proper access through internet or local area network. They can even use their tablet, smart

phone to participate into the examination using this system. At the same time teachers or

controller can create questions and can conduct exam without going exam hall and as well as

can monitor exam progress in live mode. This system is an attempt to remove the existing

flaws of manual system to conducting exams.

1.2 Objective

• To develop online base live exam system thus the examination process could be

monitored in live mode and participant can attend in the exam remotely

Page|2

1.3 Justification of Study Although there are several online based exam system running around the world but for ACM

contestant selection in the country is not shown yet. Moreover its live monitoring

functionality gives it a distinction attribute from other existing system. So we have wide

scope to work on this system.

1.4 Scopes of study

• Online live exam system is designed for any kind of educational institutes

• Teachers could view the exam status as soon as they give answer of each question

• Teachers and students can access the system from remote location

• No restriction of examiner present in exam room

CHAPTER 2: LITERATURE REVIEW 2.1 Review of Relevant Literature There are several researches and projects focused on developing better ways to manage e-

exam systems and e-learning system. Some of these researches focused on various sections

of the system and these includes Schramm (2008) looked at e-learning web based system that

could simply offers and grades mathematical questions with infinite continued existence.

Therefore it needs the capability for in and output of mathematical formulas, the dynamic

generation of plots and the generation of random expressions and numbers. The idea of the

generic software is to present an empty templates to the teacher who would like to develop

his required e-exam for the needful topic (mathematics, language, science, etc) and desired

set of exam kinds (multiple choices, matching between words, fill in blanks, etc).

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. Another paper (He, 2006) presents a web-based educational

assessment system by applying Bloom’s taxonomy to evaluate student learning outcomes and

teacher instructional practices in real time. The system performance is rather encouraging

with experimentation in science and mathematics courses of two local high schools.

Page|4

Another paper proposed web based online examination system (Rashad et al, 2010). The

system carries out the examination and auto-grading for students exams. The system

facilitates conducting exams, collection of answers, auto marking the submissions and

production of reports for the test. It supports many kinds of questions. It was used via

Internet and is therefore suitable for both local and remote examination. The system could

help lecturers, instructors, teachers and others who are willing to create new exams or edit

existing ones as well as students participating in the exams. The system was built using.

various open source technologies AJAX, PHP, HTML and MYSQL database are used in this

system. An auto-grading module was generalized to enable different exam and question

types. The system was tested in the Mansoura university quality assurance center. The test

proved the validity of using this kind of web based systems for evaluates students in the

institutions with high rate of students.

An online website for tutoring and e-examination of economic course aimed to present a

novel software tool can be used for online examination and tutorial application of the

syllabus of economic course (EL Emary and Al Sondos, 2006). Also, among the main

interests of the paper is to produce a software through it we make sure that students have

studied all the concepts of economics. So, the proposed software is structured from two

major modules: The first one was an online website to review and make self-test for all the

material of economic course.

The second part is an online examination using a large database with bank of questions

through it the level of students can be evaluated immediately and some statistical evaluations

can be obtained. The developed software offers the following features: 1) Instructors could

add any further questions to maximize the size of the bank of questions. 2) Different

Page|5

examinations for each student with randomly selected questions from the bank of questions

can be done. 3) Different reports for the instructors, students, classes etc. can be obtained. 4)

Several students can take their exams simultaneously without any problem inside and outside

their campus. The proposed software has been designed to work base on the client server

architecture. Electronic exam is a difficult part of e-learning security (Huszti and Petho,

2008). The paper describes a cryptographic scheme that possesses security requirements,

such that authenticity, anonymity, secrecy, robustness, correctness without the existence of a

Trusted Third Party. The proposed protocol also provides students a receipt, a proof of a

successful submission, and it is based on existence of anonymous return channels. Another

research work proposed a theoretical approach that incorporates available fingerprint

biometrics authentication technologies in conjunction with e-learning environments to curb

unethical conduct during e-learning exam taking (Levy and Ramim, 2007). The proposed

approach suggests practical solution that can incorporate a random fingerprint biometrics

user authentication during exam taking in e-learning courses. Doing so is hypo the sized to

curb exam cheating in e-learning environments.

Ayo et al (2007) proposed a model for e-Examination in Nigeria where all applicants are

subjected to online entrance examination as a way of curbing the irregularities as proposed

by the Joint Admissions Matriculation Board (JAMB), the body saddled with the

responsibility of conducting entrance examinations into all the Nigerian universities. This

model was designed and tested in Covenant University, one of the private universities in

Nigeria. Their findings revealed that the system has the potentials to eliminate some of the

problems that are associated with the traditional methods of examination such as

impersonation and other forms of examination malpractices. Based on the development of e-

Page|6

learning in the only Open University in Nigeria (Ipaye, 2009), discusses the process of

establishing e-learning environment. Another paper seeks to solve a part of that problem by

designing and developing a web application where tests in multiple choice formats will be

taken online and graded immediately (Akinsanmi et al, 2010). The web application relies

solely on Microsoft developed technologies. It runs on the Microsoft.net framework, uses the

ASP.NET web server, C# as the intermediate language, ADO.NET to interact with the

relational database and Microsoft SQL server as the relational database.

A successful journey of online learning and exam system that is community driven

and based on open source platform is Moodle. Moodle is highly flexible open source

learning platform. With comprehensive, customizable and secure learning

management features, it can be used to create a private website for dynamic online

courses. The acronym of Moodle is “modular object-oriented dynamic learning

environment” is also known as a learning management system, or virtual learning

environment. The platform can be used for e-learning projects in University,

Corporate training, School and other sectors.

CHAPTER 3: METHODOLOGY

3.1 Model

Following steps are followed to achieve the goal of the project.

Figure 1: Waterfall Model The waterfall Model illustrates the software development process in a linear sequential flow.

Waterfall approach was first SDLC Model to be used widely in Software Engineering to

ensure success of the project. In "The Waterfall" approach, the whole process of software

development is divided into separate phases. The project steps are described below.

Page|8

3.2 Justification of Methodology

• Simple and easy to understand to use.

• Easy to manage. Each phase has specific deliverables and a review process.

• Works well for smaller projects where requirements are very well understood.

• Well understood milestones.

• Easy to arrange tasks.

3.3 Description of Methodology

Requirements: All possible requirements of the system were developed are captured in this

phase and documented in a requirement specification doc.

Design: The requirement specifications from first phase were studied in this phase and

system design is prepared. System Design helps in specifying hardware and system

requirements and also helps in defining overall system architecture.

Implementation: With inputs from system design, the system was first developed in small

programs called units, which were integrated in the next phase.

Integration and Testing: All the units developed in the implementation phase were

integrated into a system after testing of each unit. Post integration the entire system is tested

for any faults and failures.

Maintenance: As this the university project so it was not possible to get feedback from

client side to evaluate the result from client aspects.

5.2 Result and Testing Software testing is any activity aimed at evaluating an attribute or capability of a program or

system and determining that it meets its required results. It is a process of executing a

program or application with the intent of finding the software bugs. Software testing methods

are traditionally divided into white-b0x and black-box testing. These two approaches are

used to describe the point of view that a test engineer takes when designing test cases.

1. White-box Testing: White-box testing also known as clear box testing tests internal

structures or workings of a program, as opposed to the functionality exposed to the end-user.

In white-box testing an internal perspective of the system, as well as programming skills, are

used to design test cases. The tester chooses inputs to exercise paths through the code and

determine the appropriate outputs. This is analogous to testing nodes in a circuit, e.g. in-

circuit testing (ICT). While white-box testing can be applied at the unit, integration and

system levels of the software testing process, it is usually done at the unit level. It can test

paths within a unit, paths between units during integration, and between subsystems during a

system–level test. Though this method of test design can uncover many errors or problems, it

might not detect unimplemented parts of the specification or missing requirements.

Black-box Testing: Black-box testing treats the software as a "black box", examining

functionality without any knowledge of internal implementation. Black-box testing methods

include: equivalence partitioning, boundary value analysis, all-pairs testing, state transition

tables, decision table testing, fuzz testing, model-based testing, use case testing, exploratory

testing and specification-based testing. Specification-based testing aims to test the

Page|31

functionality of software according to the applicable requirements. This level of testing

usually requires thorough test cases to be provided to the tester, who then can simply verify

that for a given input, the output value (or behavior), either "is" or "is not" the same as the

expected value specified in the test case.

CHAPTER 6: CONCLUSION

Online live examination system is the way of improving examination activities fast and

efficient. This software is interactive and user friendly has all the command controls that

would allow student successfully accomplish the exams have been implemented using the

simplest graphic styles. All users’ needs to do are to register by fill up the signup form with

their Id, Name, Phone, Email and Password. The students and controller both have to pass

authentication to log into the system. The most beautiful feature is to monitor the exam from

control room and instantly got the total examination picture.

6.1 Future Works

1. Currently no graph or figure insertion facility is available. So it will be added in next

work.

2. No emulator is available when participant answers the question. It will be added in

next work.

3. Mobile interface is not available. So it will be added in next work.

4. More user friendly interface will be added in next version.

Page|33

6.2 Recommendation and Findings Online examination system considering benefits to the society the following issues are

recommended

1. University Education: The online entrance examination would be very useful in this
