1.0 Introduction And Historical Background

Computer since its evolution has made considerable impact to various areas in one society and the world in general. Its scientific study discovery and development both in the fields of science and technology owned to the strange swiftness, exact and accuracy with its activities of computer in many aspect of human endeavour lead to the speed and accurate execution of length and cumbersome fast.

Nevertheless, computer has been applied in most fields these days due to its benefits. It has been applied in the following areas.


Computers are used as an aid to students hearing, it acts as a patient teacher which allows learning at your own pace, through the use of multimedia.


Medical records of patients can be stored for later retrieval through the sue of computer thereby assisting in the tracing of medical history of patients for appropriate treatment, also due to the emergence of internet, later medicine is now possible (a situation whereby a patient can be treated via the internet.


Most business and large firms uses a computer package called word processing to write letters, memos and report. A word processing program makes correction, editing of documents quickly and easy resulting in a neat and readable output. Also the emergence of internet has made a business possible for buying and selling of products through the internet (i.e. E- commerce)


Some companies employ master job with the aid of computer based training program which most of them use in simulation technology and other package like CAM (computer Aided and manufacturing) and CAD (Computer Aided design) are used in design and manufacturing of other products.

Other areas of which computer application has been applied are in computerization of some government owned parastatals billing system (NITEL and PHCN) and computerization of airline reservation. Due to this and other mentioned benefits and reasons, computer is without guiding ground (popularity) while scientist, artists, engineering, doctors, business and education sectors etc, found computer helpful. Some computer packages used in achieving these goals are AutoCAD, DBASE, PowerPoint, etc.

In addition, it can helpful in the computerization of federal Polytechnic Nekede grade Point Average Computation system. The adopted manual method by the examination records and statistics and computer science department formally used in the execution and processing of both Grade point Average Computation System in accurate, slow and reasonable as it goes without human labour would create chance for eliminating mistakes and oversight, accuracy as a result of manual preparation of Grade Point Computation

Historical Background

According to Richard and Jeffrey (1988) computation is the process of performing mathematical operations on data. It is the only data processing techniques that produce new data (information/output), it is the ability to perform calculations quickly limitless millions of multiplication problem for record that gives computer their reputation of miraculous tools.

John (1997) a computer scientist and a writer to the success of a computer magazine once stated a major computer merit that cannot be cost in the computer speed shown in the processing of data within few seconds which when rated and compared with human labour would normally take days, weeks, months and even years, office academic institution etc are therefore advised and encouraged to embark on computerization.

1.1. Statement Of The Problem

The problem is to investigate the way the computer science department in federal Polytechnic Nekede prepare the grade point processing and analyze the system, design and implement a new computerized system that would timel6y and effectively process and transmit data.

1.2. Purpose Of The Study

The Grade point Average Computerization system is the focus of this project work. This study is carried out to examine the existing system in an attempt to identify its problems and the system required as to surface with relevant facts that will be of help in the design of a computer based.

Grade point Average computation will help management in the computation and preparation of a computer based package for student’s grade point.

This program (Grade Point average Computerization system Version 1.0) is very simple, structured to a reasonable extent quite educating and overall well documented.

The study has much usefulness such as:

  1. Fasting up the rate of computing students Grade and scores thereby the manually records and statistics department labour function eliminated.
  2. Provision of relief to tedious repetitive clerical work in preparation of grade Point average computation

1.3. Significance Of The Study

This study will go a long way into helping the management of computer since to cope with the problem encountered as a result of using manual system in the preparation of exam score and students records. It is hoped that this study will help in the efficient and effective operation of computer-based grade Point Average Computation system.

1.4. Scope Of The Study

This study shows hoe to change the traditional way of presenting compeer science “Grade Point” a computerized (automated) mode. it is of great important to the management of the school and the record and statistics and computer science department. This goes a long way to helping stop those problems that prove detriment to the calculation of student’s grade point (G.P)

1.5. Limitation Of The Study

Mainly due to time limit and difficulties in data collection this study has been limited to computerization of exam score/grade point (G.P) for morning and evening program students. The program is under the security of the following:

How to nail it on the head during your project defence

You are through with writing that project. Now what?

You have found yourself at that point where you have to defend what you have written. Of course you have to stand in front of your supervisor and other literary personalities to prove that you know what you wrote in your project paper. Unfortunately, the more you think about it, the more it looks like you are about to face a legion. It is not a war. But the emotion of dread welling up inside of you makes it look like one. So now you are asking yourself questions.

  • How am I going to start?
  • I hope I will do well enough to get an A.

You really want to nail it, but you need to come to terms with exactly how to get everything in perfect control. Especially your emotions of fear that seem to make a wreck of you every time you think about public speaking.
So here is the deal. I want to help you avoid that feeling that would ruin your precious moment if you dare to let it. And we are going to do it together.

I am going to highlight some very important tips to help you get in control for you to be comfortable enough to move from that feeling of DREAD to CONFIDENT; and making an awesome Impression for that great rating your supervisors should be giving to you so freely.

Consider these tips as you prepare for your defence. We will be taking them one after the other so here we go.

Watch Your Body Language And Keep It Confident:

Can you tell that a person is falling apart if they look confident? … If I can second guess you rightly, am sure you answered no to that question. Remind yourself that you need to come out that way. Now this might seem like a huge big deal when you are dealing with the foreboding. Maintaining a poise of confidence is very important. So find your most comfortable position, sitting or standing and draw up your body. You must exude confidence. It is something you need to do for yourself. People can only see what you allow your body language to show. So you must endeavour to put that out. Remember the story of David and Goliath? … At the end of your defence day, you want to be David.

Dress In Your Most Comfortable And Impressive:

Am sure this one is a no brainer. However I must highlight that you choose comfortable pieces. You don’t want to look so good and yet look like you were forced to wear something that does not belong to you. It’s great to ensure that as impressive as your clothes are on you, that they are also very comfortable.

Speak With Authority:

Going hand to hand with that aura of confidence is your most powerful asset:your words. If you look that confident, your words must not come out like whimpers. To be able to pull this off, you definitely need to speak as deliberately as possible in expressing yourself. Let them also hear what they see.

Use, Your Gestures:

I have often found this to come to my rescue in dealing with shyness and conveying my confidence. Usually it gives you an edge to also drive home your point. You must, however, ensure that you do not over use it. It doesn’t mean that your hands should be flying all over the place. That would be absolutely unnecessary. If you do this well, after a while you will realize that you are not as self-conscious as you used to be at the very start. For most situations, it would have completely disappeared altogether; leaving a really confident you talking.

Have A Good Opening And Closing Line:

Make sure you have perfected a good opening line. You should also be armed with a good closing line too. Try and rehearse it to a friend. If for the first time you presented it, your friend does not say “wow, that’s beautiful” or something like that; just know you need to keep refining it until you get the perfect line. Both opening and closing lines will go a long way in how impressed your panel gets to rate you high.

Make Sure You Know Your Work:

Certainly you should understand how important it is to know your own work from start to finish. Not having in-depth knowledge of your own work is tantamount to a suicide mission. Why should you kill yourself?
When all is said and done, this is what you came to defend in the first place. You should know your work from A to Z.

Prepare For The Questions:

Now this part is truly essential. You must be sure you do not floor all the good work you did on your presentation by not answering correctly. You must pay attention to the questions you are asked to be sure you will give the right answer. Many people get it wrong at this stage and spoil their good presentation. When you do not understand any question do endeavour to ask the person to expatiate what they mean before you answer.

These tips are by no means exhaustive, but applying these tips will give you some necessary advantage you need for a great outcome. Of course that outcome would mean that you eventually earn all your points on this project.
