1. INTRODUCTION

1.1 Background

Online examinations, sometimes referred as e-examinations, are the

examinations conducted through the internet or in an intranet (if within theOrganization) for a remote candidate(s). Most of the examinations issue results

as the candidate finish the examination, when there is an answer processing

module also included within the system.

These examinations are conducted as open-book typeexaminations. Candidate is given a limited time to answer the questions and

after the time expiry the answer paper is disabled automatically and answers is

sent to the examiner. The examiner will evaluate answers, either through

automated process or manually and the results will be sent to the candidate

through email or made available in the web site.Today many organizations are conducting online examinations

worldwide successfully and issue results online.

There are advantages and disadvantages in online examinations. The

main advantage is that it can be conducted for remote candidates and

evaluation of answers can be fully automated for MCQ questions and other

essay type questions can be evaluated manually or through automated system,depending on the nature of the question s and the requirements. Also online

examinations can be conducted at any time and does not incur higher cost as

traditional exam scenario as there is no paper work involved(eg: printing exam

papers, prepare paper admissions etc) , there is no invigilators, also no

need of arrangement of exam centers. When comparing with traditional

exam scenario the cost for an online examination will be almost zero after theonline exam system is establishment and if maintenance cost is not

considered.

The disadvantage of the e-examination is the inability of invigilating.

There are methodologies used in these examinations, when registering

candidates and presentation of questions, so that to test candidates knowledge

and skills. However with a limited time , candidate is not capable of

totally depend on the reference materials or a supporting person.

1.2 Objectives

This Web Application provides facility to conduct online examinationsworldwide.

It saves time as it allows number of students to give the exam at a time and displaysthe results as the test gets over, so no need to wait for the result. It is automatically

generated by the server.

Administrator has a privilege to create, modify and delete the test papers and itsparticular questions.

User can register, login and give the test with his specific id, and can see the resultsas well.

1.3 Purpose and Scope

1.3.1 Purpose

The purpose of on-line test system is to take online test in an

efficient manner and no time wasting for checking the paper. The main

objective of on-line test system is to efficiently evaluate the candidate

thoroughly through a fully automated system that not only saves lot oftime but also gives fast results.

1.3.2 Scope

Scope of this project is very broad in terms of other manually taking exams.

Few of them are:-

This can be used in Educational Institutions like Schools,Colleges, and Private Institutes to conduct logic tests of their

students on a regular basis.

Can be used anywhere any time as it is a web based application

(user Location doesn't matter).

No restriction that examiner has to be present when the

candidate takes the test.

2. SURVEY OF TECHNOLOGIES

This project is a web application that is developed in PHP having MYSQL as back end.

1. Database Design (MYSQL)

MySQL is characterized as a free, fast, reliable open source relationaldatabase. It does lack some sophistication and facilities, but it has an active

development team and, as it goes from release to release, more capabilities are

added. At certain times there will be a trade-off between speed and capabilities,

and the MySQL team intend to keep their database engine fast and reliable.

2. Input Design (DREAMWEAVER)

Ease and efficiency of use. The ability to create consistent looking web pages. Managing and updating websites effectively. Easy to upload using FTP.

3. Coding (PHP, JavaScript)

PHP is one of the most popular server side scripting languages running

today. It is used for creating dynamic web pages that interact with the user

offering customized information. PHP offers many advantages; it is fast, stable,

secure, easy to use and open source (free).PHP manages freeing all resources. Users does not required to free file

handle resource, database resources, memory, etc, unless programmer need tofree resource during script execution.(All resources are released after script

execution).

PHP code is inserted directly into the HTML that makes up a website.

When a visitor comes to the website, the code is executed. Because PHP is a

server side technology, the user does not need any special browser or plug-ins to

see the PHP in action.

JavaScript is a browser based programming language that actually runs

client side. This means that any code that is written in JavaScript is delivered

along with the web pages and the scripts that are written, actually run from

within the users' browser rather than directly on the server that is serving the

web pages. It can be interactive even when we are not connected to the Internet.

Since the code is typed directly into your HTML files, we can create JavaScriptwith software as simple as a plain text editor. We can quickly test and modify

JavaScript code. JavaScript functionality is built into most new web browsers

since 1996, so there is no extra software for the viewer to download or install.
