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 this test 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 if needed.

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 commonly knows 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.
