1.0 INTRODUCTION INTRODUCTION
This is a web-base web-based d int elligent mult iple-choic iple-choic e-question e-question examination system, named Online Intelligent Quiz System (OIQS), for assessing students. It is a syst em by wh ich stu dents can appear appear in a quiz from anywhere of the world w here there there is no int eraction between between pencil and paper rather interaction between between c omputer and human being. We use the term intellig ent here as as the syst em generates generates questions i ntelligently. There are many definitio ns of intelligence but we use the term int elligence in the sense that the sy stem generates generates the a new question of a quiz by depending depending on the result of th e question last answered and for the same same quiz of a subject it generates generates dif ferent questions for diff erent erent st udents. The The questions vary stud ent to stud ent for the same quiz whil e they are sitting in t he quiz at the same time. Teache Teachers rs can use the OIQS OIQS for evaluating stu dents effectively, efficiently and perfectly. An y un ivers Any iv ers it y, co ll ege, sch s ch oo ooll o r educ ed uc ati onal on al i ns ti tu te c an u se th t h is syst em fo r th eir organization organization to take quizzes. quizzes. Today Today it i s the more efficient and effective methods of assessing d istant st udents. One of the main benefits of ou r syst em is automated automated marking, that is, teachers do not need to check t he answer answer sc ript as they they do in manual quiz. It It saves valuable time of a teacher. On On t he other hand, students c an s core according t o his/her merit level and it will gi ve feedback feedback about a student in w hich side he/she is weak. weak. In recent years, years, the use of onl ine quiz systems has become quit e popul ar due to pressures of increasing class sizes and the ne need ed for more efficient and effective methods of assessing dis tant students. It is due to the popularity of d istant education.

2.0 CURRENT SCENARIO OF QUIZ SYSTEM
Still now maximum educational institutes have been using manual system to take quiz. In the recent year a few instructors of some institutes have been using web-based M.C.Q. quiz qu iz system. system. Actually, it depends depe nds on how much web technology a country takes or uses. For example, in Bangladesh it is rare to use a web based bas ed quiz system. But in case of U.S.A. it is a general case to use a web based quiz system.
2.1 MANUAL QUIZ SYSTEM In the early days it was the most popular methods of assessing student. Still now the system is quite popular to the students as well as to the teacher. In this system there are several problems that we faces in a common way. Some of those problems are: Manual system requires pen/ pencils and paper. Teacher needs to spend time to script checking. Student needs to wait to get their result up to the teacher finishes the script checking. These are the most common problems of manual quiz system that rotated each and every time of quiz held. For these causes the popularity of manual system decreases day by day and online intelligent quiz system is system is taking the place of the manual system.
2.2 WEB BASED QUIZ SYSTEM Now a As daythe thetechnology web base quiz system is gettingout popular with the a tremendous speed. is spreading through the world automated system will also taking the places of the manual systems. Currently big institutes are running their online quiz systems at a very successful rate. As the time is progressing the online quiz is making interest to the faculties and also to the students. In the big cities and organizations people are getting understand that how the online quiz system is better and efficient. With in the recent time this system will be taken place to this techno world. But this system also has some lacking. If this system has the th e intelligent part then it will be a perfect perf ect one. The problems that may occurs with web based q quiz uiz system: Can’t evaluate the student perfectly. Can’t generate the proper feed back of the students.
10
3.0 FEED BACK FROM CURRENT SCENARIO
From the previous two systems I realize to solve s olve the problems of those systems to get a standard s tandard quiz system. In the previous two systems the things that are short from a standard quiz system, to fix it up I design an intelligent system, which will work according to the web base system. From this intelligent system we can omit the manual system’s problem criteria because it work as a web base system, which is totally automated. It also omit the general web based system because it gives the evaluate option for the students performance and feed back criteria. To get a s standard tandard quiz system I tried to join the intelligent system that I designed for my thesis project. This will help to remove the current system’s problems.

4.0 PROPOSED SYSTEM
In recent years, the use of electronic o nline quiz sy stems has become qui te popular due to pr essures of inc reasing reasing class sizes, and and the need for more efficient methods of assessing distances students. This This thin g mot ivates us to wo rk with web based based quiz syst em. We also have tried to eliminate the problem wit h general general web based quiz sys tem and decide to create a web based intelligent quiz sy stem. In In ou r th esis project, we have tried to develop develop an “ Online Intelligent Intelligent Quiz System” System” which w ill be popul ar in both t he students and teachers. teachers. To develop develop th e system we collected some documents from w eb. Then Then we have analyzed analyzed those documents and tried to fi nd some logic from there. As a step of development development w e collected requirements where we have conducted a survey. In that survey we too k teachers a and nd st udents opinion s to make the system more meaningf meaningf ul. For that we made a question set and gave it to some teache teachers rs and st udents. They gave their their opi nions on th ose scripts . In In below survey details are given.
4.1 SURVEY
To make an effective and efficient Online Intelligent quiz system we need some findings. We believe that our findings will help us to make the system user friendly. Here is a short description of our system. Our system name is Online Intelligent Quiz System. System . Any University, College or School can adopt our system where education system is computerized. Teachers can take quizzes using our Online Intelligent Quiz System. System . We will use an expert part in our system, which is knowledge base. This expert part will work using AI. Our system will determine participant’s and the next questions willwill be generated the according to the performance participant’s performance. Our system also be able to provide feedback according to the participant’s demand.

For th e same quiz of a su bject Question Generator Generator may generates diff erent erent question f or diff erent erent student. That That is question m ay very very stu dent to stu dent for the same quiz while they are appear appear in t he quiz at the same ti me. To design the softw are we use 3-tier architecture. As 3-tier architecture divid e the whole sys tem into thr ee parts, so to design t he system we divide ou r sys tem into three subsys tems. These These are are Client Client Tier/ Client Client
20
subsystem, Business Logic Tier/ Business Logic subsystem, and Database Da tabase Tier/ Database Database sub sys tem.
5.3.0 ASSUMPTIONS AND DEPENDENCIES We assume that s tudents are interested interested on i ntelligent qu iz where diff erent erent st udents might appear in answering answering diff erent erent question s for th e same quiz depending on h is/her performance. Tea Teachers also int erested erested to take intelligent quiz w here he/she he/she can evaluate evaluate a stud ent perfectly. The users of th e OIQS OIQS system are the school/college/university school/college/university students, teachers and the admin admin who c ontrol t he system and those institutes must be computerized. Any An y in st it ut e mi gh ghtt h have ave t o Inter In tern n et co c o nnect nn ectio ion n tto o us e OIQS syst sy stem em because this is a web web based application.
5.4.0 GENERAL CONSTRAINTS OIQS is a generic application as it may be use by m any users of many OIQS inst itutes. So the constraints that we have to cons ider might be in generic sense.
5.4.1 Hardware and software environment To develop t his OIQS OIQS we use HTML HTML for cli ent-tier, PHP PHP and JSP for Business-tier and MySQL for the database-tier. So the hardware environm ent r equirements equirements t o use of t his sof tware are are at least least Intel Penti Pe nti um II or equiv alent pro cesso r, at least least 64MB RAM, RAM, a database server that need a disk less server but can be the same machine machine fro m whic h the softw are will r un. So, all all of these requirements requirements may be a const raint to t he clients. There There are are four sof tware components required for t he propo sed system. The The four components are as as follo ws: Operating Opera ting System Web Server Database Web We b Brow ser Operating Opera ting System

One One of the advantages advantages of usi ng the Linux operating operating s ystem is th e speed speed at at which performance enhancements enhancements and s ecurit y p atches are made available ava ilable since it is an open source prod uct. Web Server The availabl availabl e web server’ s platf orms are IIS IIS and Apach e. Sinc Sinc e Apache is open source, softw are securit securit y patches tend t o be released released faster. One of the downsides to IIS is its vulnerability to virus attacks, something that Apache rarely rarely has pro blems with . Apache off ers PHP; PHP; a language considered to be the C of The next part is th e end end u ser environment. Before we have explain that w e have have assume that th e end users are not so much aware about about t he computer and they are not so much interested to divert their activiti es to the automated automated system fro m the manual syst em.
5.4.2 Security requirements Securi ty r equirement Securi equirement i s th e next part. As we developed developed OIQS OIQS by us ing 3tier architectu re, so this s ystem is secured. Because Because end end user can’t access the database directly as in 3-tier architecture database are accessed accesse d via business lo gic.
5.4.3 Performance requirements Now w e will d iscuss about the perform ance requir requir ements. ements. This OIQS OIQS syst em might be faster than oth er web based based syst em. Because Because this sys tem is d eveloped usi ng HTML, HTML, PHP, PHP, and MySQL that are open sour ce and can run faster.

5.5.0 5.5 .0 Goals Goals and g uid elines Our main goal is t o develop an effective effective and effici ent s ystem. To To design this syst em we gave priori ty end users expectations.
The KISS KISS princ iples The full meaning meaning of KISS is “ Keep Keep it Simple Stup Stup id” . IItt m eans we need need to design the sys tem in a very simpl e way. way. For For a good d esign, we nee need to cons ider the Criteria for g ood su b-system/UM b-system/UML L d iagram design. These These criteria are Coupling and Cohesion. Coupling measures the degree of interconn ectedness ectedness b etween design c lasses/components lasses/components /sub-systems. For a better design low co upling is preferable. Cohesion, on the other hand, measures the degree to which an element (class/component/subsystem) contri butes to a single purpo se. For a better design high cohesiveness is p referable. referable. Our Our design follow s th ese two c riteria. We We also also t ry to make the design considering us er satisfaction.
Our Emphasis We gave emphasis emphasis on the effectiveness of the sy stem that is correctn ess of the system and and then efficiency of the syst em. Efficiency incl udes various things; these are speed of the syst em, how much memory the sy stem needed needed when running, how m uch easier easier the soft ware to use etc. The The automated automated syst em is int roduced to ensure faster and secured activities of the processes. We We design the system emphasis in th ose things . One One exa example mple of emphasizing is t hat to m ake th e system faster we chose thin c lient and thick s erver. erver.
Worki ng, Lookin g, or feeling feeling Our main objective is to satisfy th e users. users. If If th ey feel good by using thi s syst em then it will b e really really a very very goo d job done.
5.6.0 ARCHITECTURAL STRATEGIES We chose all the thin gs that are software architecture, programming languages to develop thi s OIQS OIQS considering a good design strategy. After Af ter co ns id ideri eri ng t hese hes e ffact actor or s w e arriv arr ived ed at th e fol fo l low lo w ing in g arc hi tec tu ral infrastructure.

5.6.1 SOFTWARE 5.6.1. 5.6 .1.1 1 Programm ing Language Programming L angua anguage ge for Client Client Tier We use HTML HTML and PHP to desig n the t he cl ient t ier. Because HTML and and PHP PHP are ea easy sy to use and and it w ill be helpful fo r us to design the client tier using HTML and PHP. PHP.
Programming Language for Business-tier We use PHP PHP and and JSP to design t he Busin ess-tier ess-tier because it is an open sourc e programming language language that is wi dely popular on t he we web. b. PHP PHP is well known for fast per performance formance and and it is also well known for i ts quick and easy easy w eb d evelopment evelopment capabilit capabilit ies. PH PHP is an easier easier pr ogramming language to learn th an J avaScript avaScript because because th e core language is small. That is why it is ea easier sier to u s to d esign the Business-tier usin g PHP. PHP.
Programming Language for Database-tier We us e MYSQL MYSQL to design th e database-tier. database-tier. The MySQL database has become the world's most popul ar open source database database b becau ecause se of its cons istent f ast performance, high reliability and ease of us e.

7.0 CONC CONCLUSION LUSION
In this thesis, we have focused on the automated system, which replaces the manual quiz system. But the interesting thing is that the thesis is not just an online quiz system; it has its own intelligent capability. This was actually our target feature of our thesis. Basically, we have tried to introduce the evaluation method of student-performance and the feed back of the student in the online quiz. Here, the questions are appeared according to the previous answer of that student. We have implemented it in our thesis and it works successfully in our system. In this system, an educational educationa l institute can make their examination procedure automated. It gives the opportunity to the authority to register teachers for different subjects and also give the facility to the students to register their courses for the examinations using the OIQS. Though this is a MCQ based quiz system but it is a perfect MCQ based online quiz system that gives a lot of facilities to the users, as a modern quiz system should have. This system is designed basically for the educational institute but also can be developed for other examination systems like job interview, quiz contest and for other criteria.
