2. Introduction and Objectives of the Project a. Introduction The motive behind the creation of Online Examination System is to change the way of conducting and attending examination. In this way not only we can improve the academics but also we can save a lot of resources. And more, it’ll bring more transparency, accuracy in evaluation and save money, man power and time. It will also eliminate means of unfairness in the exams. The new system will improve the accuracy and speed of the student and help them to find their true potential, their weak and strong, so that they can work in right direction. Online examinations contents providers to focus oncreating efective assessment questions and focusing onexam’s feedback delivery to students. In the paper we presenttechniques that are pertinent to the elements of assessmentprocess. answers submission! computeri"ed grading! andfeedback after submission.

b. Background Now a day computers are being used every where, in every field and it is becoming the key solution of every problems including common and uncommon one. But the examination system of schools and colleges are still following the old paper based exams, which have some disadvantages and problems that can be eliminated if we’ll adopt a new way for conducting examinations. The paper based exams have some drawbacks, i.e. it uses lots of resources like papers, man power and money. It is also very time consuming since it takes time to evaluate the copies one by one and assigning marks, which is very time consuming task. And there is no guarantee that the result is 100% correct. There are some more problems with papers based examinations that are listed below.

i. Problem with existing system 

The existing system that is paper based system requires a lot of resources like paper, man, time and money.

5



The current system all works are paper based from preparing questions to evaluating answer sheet, from attendance to mark sheet. Every steps use papers.



The existing system makes frequent use of man power at every level. Like for preparing question papers, guarding in examination hall, for evaluating answer sheet.



Since man performs every task hence it is very time consuming and there is no guarantee of 100% accuracy. And it requires money for paying for them which directly increase the examination fees.



There is lack of transparency in the evaluation of answer sheet. Students are kept in dark because they are not shown the answer key and how their scores have been arrived at.



Question papers are always at risk of being leaked.



There is a long delay in result publication.

ii. Solutions in new system 

Online system solves all the problems that make data storage risky, data access complicated and data processing slower and error prone.



Much time is saved from maintaining records of student details, question papers, marks, results etc.



To prevent the leak of question papers this online examination system follows the following measurements :  Diversified sources and large number of questions in the question bank.  Questions will selected randomly from question bank for each student. So that, no one knows which question they will get.  The questions will be encrypted digitally and decrypted only at the time of examination.



New system allows the students know their results and rank shortly after the exam.



This online examination system is user-friendly. 6



It minimizes the use of papers and the requirement of man power, money and time.

c. Objectives The main objective of this system is to make an online examination system where different schools and colleges register for conducting examination. Students can also register themselves to take part in the examinations conducted by any institutes. The institutions (school/colleges) will prepare question papers and notify about schedule of examination to the students so that students attend examinations. During examination, randomly selected questions from a large question bank will be asked from students. It will also give the following benefits:   

Minimize the use of paper. Reduce the requirement of man power and save time. Reduce the cost of organizing the examination. Make the examinations real time.

3. Project Category This project comes under the category of web application. It will be available to everyone, anywhere, anytime. The frontend or user interface is designed by using HTML. HTML is the standard markup language for creating web pages. It describes the structure of the webpage. HTML elements are the basic building blocks of any web page defined as tags. To make the web pages attractive, CSS is used. CSS stands for Cascading Style Sheets. CSS is the stylesheet language used to describe presentation of a document written in HTML or XML including SVG also. For making web pages dynamic, interactive and for validating the forms, JavaScript is used. JavaScript is a full-fledged dynamic programming language that, when applied to an HTML document, can provide dynamic interactivity on websites. 7

The backend is programmed in PHP, which is server-side scripting language designed specifically for the Web. Within an HTML page, we can embed PHP code that will be executed each time the page is visited. PHP code is interpreted at the web server and generates HTML or other output that the visitor will see. AJAX used for asynchronous communication between client and server. AJAX (Asynchronous JavaScript and XML) is used for modifying the content of web pages without reloading it. For storing data used by application, MySQL Database is used. MySQL is an open source, fast, reliable and powerful Relational Database Management System. For database connectivity, PDO (PHP Data Object) is used.
