ONLINE EXAM MANAGEMENT SYSTEM

INTRODUCTION OF ONLINE EXAM MANAGEMENT SYSTEM:

Are you looking for Online exam management system for your final year project? We are here to help you. You can contact us 
We have a lot of students in schools and colleges which are evaluated on the basis of their performance of study in their exams periodically. So is done through pen and paper method of examination.
Then this is sent to the then respected teacher after binding, giving proper serialization and many more attributes, for the evaluation which manually done by the teachers, few other question which is mc qs are also evaluated manually by the teacher.
There are a lot of complications in this traditional approach of evaluation after every few weeks or sometimes on daily basis. So to decrease its procedure and making into another level of giving and taking exam we invented this system on which students will work on the system with their respected id and password.
Then they have the interface where they have an exam to happen on particular place and time. We have all question put by the teacher in that with the space available for the answers to write and for mc qs they have the option to tick the answer.
Here mc qs are evaluated at the moment as we have to just match the back end answers with the choices and the subjective type questions are stored and given to the teacher online for checking.
Teacher evaluates the questions and then provide the marks accordingly the marks recorded are shown to the students as their results and hence they are evaluated very precisely excluding the use pen and paper, distribution of marks in every class and removing the difficulties of schedule announcements.
We can even extend its usage to another level by just using it’s for the purpose o announcement making and mock test. homework provider and many more usage are there as we want.

SYSTEM MODULES OF ONLINE EXAM MANAGEMENT SYSTEM:

Our system is comprised of few important interfaces or we can say modules behind it so here we will discuss the modules related to all those interfaces and workflow further.

USER REGISTRATION:

A user here is student basically but we can say it, user, here. One need to provide his details like name, address, class, number of the contact, email, and fee for the year fee status also. These are required then enter his hit to make it saved in the database. Then we need it to use the credentials for further access.

LOGIN :

Login with the registered credentials and then move to the interface where available exams are shown.

ADMIN:

Admin panel is specially designed to facilitate all tasks that need to be done or attempted by the student user.

SET EXAM:

Admin is responsible for all kind of operation in the exams of students he designs the question paper according to the teacher of the subject in the portal and then after all kind of work like sending space for subjective type questions limiting space words and for mc q instant evaluation and for other result kind of activity it is going to update.

ATTEMPT EXAM:

Next we have the interface for the students where one can after login can see the exams available in their accounts and then they attempt that on particular venue provided for particular duration of time and then he can move in the portal too and forth for the selection of attempt questions and can finish before time as their wish.

STAFF:

Here staff’s data is mentioned with their all credentials and mainly focusing on the exam purpose they have the option to get the info on the duty venue of the exam where they have to give duty and at what time and which subject.
so as they are required to avoid the cheating incidences. so here they can go for it.

RESULTS:

Results of the exam are to be shown in this module . in this part the student ‘s result for the mc q are shown at the moment but we have the options of subjective type questions which are needed to be checked manually by the teacher as at the moment.
We don’t have such technology which can evaluate the subjective type question precisely as every student has their own way of writing the question so it difficult for the system.
So leaving it to the future. But for now, we have the option of making a system where one can evaluate all the given answer on online portal without the involvement of the pen and paper.
As after evaluation teacher give every question with answering particular marks from given weight – age of question which are calculated in the end and made available in the portal of the student account the given test or exam marks. Here they can see and improve their marks in future.

PAY:

Here we have taken module which is making the payment of the fees compulsory before taking a particular test.
This module checks the comparison between the paid status or not and then send boolean to the exam interface to show a particular test to that student or not.
if one has paid his fees that he will be allowed to give the exam and if he does not give then he won’t be allowed. In our system, we have made this optional as of now as a teacher would like to provide a test for some other student in the case without pay so this optional thing would help us a lot.
Coming to the part of attendance and timetable he can see both of them in their interface as admin announce this timetable of exams with proper information in this about the venue and other thing related to exam.
Regularly maintained by admin.Attendance is also included in this as to ensure the presence of the student at the venue, this is taken by the staff available there at the moment in the same portal and hence it will mark them present or absent.
It is mainly for the purpose of checking the cheating case as sometimes kids give exam from outside and they can cheat from their very easily.

SYSTEM REQUIREMENTS OF ONLINE EXAM MANAGEMENT SYSTEM:

Our this online exam management system needs a lot of systems as this is mainly for a lot of students sitting together and give exam so we need as many systems as many students we have.
A number of systems are to be available precisely counted the same with if few extra can give extends security sense in case of some system failure.
Every system needs ups for removing the cause of electricity loss and data loss with it as one can save their answers or end in time. For proper evaluation of test.-system needs to be of 1.3 g h z minimum cp u clock speed.
it should have minimum 2 g b ram for proper working with speed. To avoid delays in actions.
mouse and keyboard also required for typing as it is purely an exam which is in mc q and subjective combined so for fast and comfortable execution we have to use mouse and keyboard.
other we can take an admin system reserved for staff work I every room of exam along.

SYSTEM DESIGN:

Now we have to design our system before implementing it in such a way that it can execute all the work we want without any loss of data and without using any kind of functionality.
For this purpose, we have two kind diagram we use here to represent the system interaction and flow the data storage which is er diagram here. These are as follows:-
