ABSTRACT
Exam Software is a Test Management Software, which offers a complete
solution for Computer Based Test (CBT) .They are used to set up
multiple choice tests for set time periods that when submitted are
automatically corrected and the results logged beside the student's
reference number.
FEATURES
Administrator login.
Student registration.
Management and update of student information ,instructions and
questions.
scope for fixing negative marks and maximum marks to each
question.
Display of result in the form of total score ,correct responses
attempted and non attempted questions.
WHAT IMPACT DOES IT HAVE
Physical presence at a given location is absolutely not necessary.
No time is spent on evaluation.
Results are available instantly.
The time of starting and completion of examination can be
recorded at the server and the student cannot manipulate the same.
Even for subjects that the actual examination that will not be
conducted online students can be given extensive practice and
training by holding online Mock Tests.
Trends of the examination including topic wise trends of each
subject can be easily obtained if required.

INTRODUCTION
1.1 PURPOSE
The purpose of thistest simulator is to take test in an efficient manner and
no time wasting for checking the paper.
The main objective of this test is to efficiently evaluate the candidate
thoroughly through a fully automated system that not only saves lot of
time but also gives fast results.
For students they give papers according to their convenience and time
and there is no need of using extra thing like paper, pen etc.
1.2 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 as well as in corporate world.
No restriction that examiner has to be present when the candidate takes
the test.
1.3 FEATURES:
Secure
Easy to use
Reliable and accurate
No need of examiner
1.4 OVEVIEW
The test application created for taking test has following stages
Login
Test
Result
1.5 LOGIN:-
There is a quality login window because this is more secure than other
login forms as in a normal login window there are multiple logins
available so that more than one person can access to test with their
individual login.
It include two login windows one for administrator and another one
for student.
1.6 TEST:
Test page is the most creative and important page in this project. It
consists of 2 modules namely:
Subject selection
Utilities
 Utilities:-
It includes:-
Skip and come back to the question afterwards ifneeded.
Gives the list of attempted and unattempted questions and can
go to any question directly and can either attempt or change the
answer of the already attempted question.
2. TECHNOLOGIES USED
 Front end as:
Core Java
 Back end as:
Microsoft SQL Server 2008
 Database:
SQL
 Querying language:
SQL
3. FEASIBILITY STUDY
3.1) ECONOMIC FEASIBILITY
Economic analysis is most frequently used for evaluation of the effectiveness of
the system. More commonlyknows as cost/benefit analysis the procedure is to
determine the benefit and saving that are expected from a system and compare
them with costs, decisions is made to design and implement the system.
This part of feasibility study gives the top management the economic
justification for the new system. This is an important input to the management
the management, because very often the top management does not like to get
confounded by the various technicalities that bound to be associated with a
project of this kind. A simple economic analysis that gives the actual
comparison of costs and benefits is much more meaningful in such cases.
In the system, the organization is most satisfied by economic feasibility.
Because, if the organization implements this system, it need not require any
additional hardware resources as well as it will be saving lot of time.
3.2) TECHNICAL FEASIBILITY
Technical feasibility centers on the existing manual system of the test
management process and to what extent it can support the system.
According to feasibility analysis procedure the technical feasibility of the
system is analyzed and the technical requirements such as software facilities,
procedure, inputs are identified. It is also one of the important phases of the
system development activities.
The system offers greater levels of user friendliness combined with greater
processing speed. Therefore, the cost of maintenance can be reduced. Since,
processing speed is very high and the work is reduced in the maintenance
point of view management convince that the project is operationally feasible.
3.3) BEHAVIOURAL FEASIBILITY
People are inherently resistant to change and computer has been known to
facilitate changes. An estimate should be made of how strong the user is
likely to move towards the development of computerized system. These are
various levels of users in order to ensure proper authentication and
authorization and security of sensitive data of the organization.
4. EXISTING SYSTEM
The whole process of assigning test and evaluating their scores after the test,
was done manually till date. Processing the test paper i.e. checking and
distributing respective scores used to take time when the software was not
installed.
4.1 DISADVANTAGES OF CURRENT SYSTEM
The current system is very time consuming.
It is very difficult to analyze the exam manually.
To take exam of more candidates more invigilators are required but no
need of invigilator in case of on line exam.
Results are not precise as calculation and evaluations are done
manually.
The chances of paper leakage are more in current system as compared
to proposed system.
Result processing takes more time as it is done manually.
4.2 CHARACTERISTIC OF THE PROPOSED SYSTEM
The test engine created for taking test has following features :
In comparison to the present system the proposed system will be less
time consuming and is more efficient.
Analysis will be very easy in proposed system as it is automated.
Result will be very precise and accurate and will be declared in very
short span of time because calculation and evaluations are done by the
simulator itself.
The proposed system is very secure as no chances of leakage of
question paper as it is dependent on the administrator only.
The logs of appeared candidates and their marks are stored and can be
backup for future use.

Future scope
There have been numerous cases of computer glitches, errors in content, and
security lapses reported in online examination .So in the near future the so –
called software could be made more secure and reliable.While electronic
glitches are rare, they have been known to occur, for instance when computer
crashes voided the efforts of thousands of student. There are also cases in which
the correction software has corrupted scores. so the software can be
programmed well so as to avoid corrupted scores.
CONCLUSION
The On line test System is developed using visual basic and sql fully meets the
objectives of the system for which it has been developed. The system is
operated at a high level of efficiency and all the teachers and user associated
with the system understands its advantage. The system solves the problem. It
was intended to solve as requirement specification.

    ABSTRACT Exam Software isa Test Management Software, which offers a complete solution for Computer Based Test (CBT) .They are used to set up multiple choice tests for set time periods that when submitted are automatically corrected and the results logged beside the student's reference number. FEATURES Administrator login. Student registration. Management and update of student information ,instructions and questions. scope for fixing negative marks and maximum marks to each question. Display of result in the form of total score ,correct responses attempted and non attempted questions. WHAT IMPACT DOES IT HAVE Physical presence at a given location is absolutely not necessary. No time is spent on evaluation. Results are available instantly. The time of starting and completion of examination can be recorded at the server and the student cannot manipulate the same. Even for subjects that the actual examination that will not be conducted online students can be given extensive practice and training by holding online Mock Tests.

    CONCLUSION REFERENCES INTRODUCTION 1.1 PURPOSE The purposeof thistest simulator is to take test in an efficient manner and no time wasting for checking the paper. The main objective of this test is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. 1.2 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 as well as in corporate world. No restriction that examiner has to be present when the candidate takes the test. 1.3 FEATURES: Secure Easy to use Reliable and accurate
  • 6.
    No need ofexaminer 1.4 OVEVIEW The test application created for taking test has following stages Login Test Result 1.5 LOGIN:- There is a quality login window because this is more secure than other login forms as in a normal login window there are multiple logins available so that more than one person can access to test with their individual login. It include two login windows one for administrator and another one for student. 1.6 TEST: Test page is the most creative and important page in this project. It consists of 2 modules namely: Subject selection Utilities  Utilities:- It includes:- Skip and come back to the question afterwards ifneeded. Gives the list of attempted and unattempted questions and can go to any question directly and can either attempt or change the answer of the already attempted question.

    3. FEASIBILITY STUDY 3.1)ECONOMIC FEASIBILITY Economic analysis is most frequently used for evaluation of the effectiveness of the system. More commonlyknows as cost/benefit analysis the procedure is to determine the benefit and saving that are expected from a system and compare them with costs, decisions is made to design and implement the system. This part of feasibility study gives the top management the economic justification for the new system. This is an important input to the management the management, because very often the top management does not like to get confounded by the various technicalities that bound to be associated with a project of this kind. A simple economic analysis that gives the actual comparison of costs and benefits is much more meaningful in such cases. In the system, the organization is most satisfied by economic feasibility. Because, if the organization implements this system, it need not require any additional hardware resources as well as it will be saving lot of time. 3.2) TECHNICAL FEASIBILITY Technical feasibility centers on the existing manual system of the test management process and to what extent it can support the system. According to feasibility analysis procedure the technical feasibility of the
  • 9.
    system is analyzedand the technical requirements such as software facilities, procedure, inputs are identified. It is also one of the important phases of the system development activities. The system offers greater levels of user friendliness combined with greater processing speed. Therefore, the cost of maintenance can be reduced. Since, processing speed is very high and the work is reduced in the maintenance point of view management convince that the project is operationally feasible. 3.3) BEHAVIOURAL FEASIBILITY People are inherently resistant to change and computer has been known to facilitate changes. An estimate should be made of how strong the user is likely to move towards the development of computerized system. These are various levels of users in order to ensure proper authentication and authorization and security of sensitive data of the organization.

    4. EXISTING SYSTEM Thewhole process of assigning test and evaluating their scores after the test, was done manually till date. Processing the test paper i.e. checking and distributing respective scores used to take time when the software was not installed. 4.1 DISADVANTAGES OF CURRENT SYSTEM The current system is very time consuming. It is very difficult to analyze the exam manually. To take exam of more candidates more invigilators are required but no need of invigilator in case of on line exam. Results are not precise as calculation and evaluations are done manually. The chances of paper leakage are more in current system as compared to proposed system. Result processing takes more time as it is done manually.
  • 11.
    4.2 CHARACTERISTIC OFTHE PROPOSED SYSTEM The test engine created for taking test has following features : In comparison to the present system the proposed system will be less time consuming and is more efficient. Analysis will be very easy in proposed system as it is automated. Result will be very precise and accurate and will be declared in very short span of time because calculation and evaluations are done by the simulator itself. The proposed system is very secure as no chances of leakage of question paper as it is dependent on the administrator only. The logs of appeared candidates and their marks are stored and can be backup for future use.
