10 Tips To Score More Than 90% Marks In 12th Board Exam 
It is all up to your hard work from the beginning of 12th class that whether you score more than 70% or 80% or 90% marks in 12th board exam. Now here are my tips and suggestions to score the good percentage in your 12th class.Just follow these tips and I assure you that no one can stop you from securing more percentage in your 12th board exam. 

1. Stick with Your Syllabus Book – Mind It! 
Yes, I have seen a number of students of mine run behind the big heavyweight reference books, and they underestimate their syllabus books like NCERT in the case of CBSE board. 
These syllabus books are the best to practice with. Have you ever noticed the high scoring students always stick to the syllabus textbooks and this is only because they know the true significance of that key to success book (syllabus textbooks). 
Reference books are good to study with but, reference books are for those students who wants to be a part of competitive exams after 12th class. But if you really want to score more 

2. Be Careful with your Weak Points 
What are my weak points and how to make them strong? you should always keep this question in your mind while preparing for the board exams. 
Take out your answer sheets of pre-boards and class tests etc, and take a deep look into your answers, and your mistakes, make a list of those mistakes for each and every subject. Ask yourself, will I repeat these mistakes in board exams too? 
No, say a big no, and start debugging your mistakes, do a hard work on your mistakes, scratch them to their depths, take it like a mission to convert those weak points of yours into the stronger ones 
  
is your handwriting lthy? try to make it better, if not 90 or 80% but at least 1%, but do work on it. 
is it organic chemistry? Learn it, read it and make it happen. But do not underestimate it. 
These are a sort of weak points I am talking about in this section. Recovering from your weak points which are responsible for your deducted marks will surely put you on the track of scoring great percentage in your board exam

3. Time Will Kill Your Marks 
Yes, I am talking about the time management here, this is one of the big factors responsible for marks. You are not a kid, every student knows the denition of time management, but only a few of them takes it seriously while preparing for board exams. 
It’s your 12th class dude, you will never see the school again in your life and, believe me, you will never study as you are doing right now, again in your life with such an enthusiasm. So why not make this preparation more beautiful and smart by applying time management on it.
 
So, let me explain some important key points of time management for board exam preparation. 
1. If you do, stop sleeping 8 hours, make a healthy sleep of 5 to 6 hours only and save your 2 hours from here.
 2. Study the learning subjects like chemistry, biology, economics, etc at morning time, this helps to retain a long memory of whatever you have learned while reading in the morning time.
 3. in school, take advantage of free time like sports periods and curriculum activities, practice logical subjects like math’s, physics, accounts etc. Trust me, reading or practicing in the free time of school will save a lot of time.
 4. If only 3 months are left for the board exams, then you should not join or continue things like coaching classes etc. Use that time in self-study and making notes, trust me you will understand things way better by doing self-study.
 5. Study at least 8 hours a day, if you really want to score 90+ percentage in board exams. Because this is the only thing which is required to achieve such percentage.
 6. Divide equal time of study with your main subjects. But do not forget to study subjects like Hindi, English etc. because they can prove to be real percentage boosters.
So overall you have to study at least 8 hours a day and make it 9 to 10 hours on holidays like Sunday. This feels like crazy, studying with such madness, but the 90+ achievers did that and made their percentage possible.

4. Solving Previous Year Papers Is Not That Boring 
Don’t know why the students do not understand the values of old assets. Again a huge number of students are there who spends a big money on reference books, but they even don’t try to look at the previous year papers. 
Maano Ya Na Maano, previous year papers act like a key to success in getting the mind blowing percentage in your 12th class. Don’t waste your money in buying such costly and heavy books. The internet is ruling today where you can and anything and anytime.Solving previous year question papers are like giving previous board exams. Take each and every year question paper seriously and start solving them and feel like you are sitting in examination hall of board exam. 
Do not go for answers directly without solving the question paper on your own completely, and after solving the question paper look for the answers and be a checker for yourself.
 
But if not then look for the mistakes and repeat the third point above, solving 10 such papers before the board exams will make you 10 times stronger to face the board exams. 
Previous year papers are important because they, 

1.	Let you know the difficulty level of questions.
2.	Help to	find out the repeating sequence of questions,

 So, do not waste your time and download the previous year papers above, if you haven’t. And start solving them. Also with solving the previous year papers, you can practice sample papers and guess papers too. These papers also help to predict the future of your marks.

5. Don’t Underestimate ENGLISH – Specially CBSE Students 
Physics, Chemistry, math’s, Biology, Accounts, Economics blah and blah, dude do you remember you have one more subject called English? 
Not everyone but a huge number of students does not take this subject seriously and at the time of result, this subjects becomes responsible for the drop in overall percentage.Subjects like English can be used as a booster in making a high percentage, all you need to do is to study it, at least, a day in a week. if you can maintain this, then surely this subject will support your percentage in a great way. Also, give a special attention to handwriting while preparing for English. You will secure at least 5 marks just by working on your answer sheet presentation skills. 

6. Do Your Answer Sheet Looks Filthy After You Finish the Exam? 
We are talking about 90+ percentage, it’s not a joke! even a single mark can make a big difference to 89.9% and 90%, getting me? 
So each and every activity matters while you are preparing for board exams. Neatness and cleanliness are one of them. Your answer sheet is the only thing on the basis of which you will get your marks, so everything related to your answer sheet matters. 
Practice on making your answer sheet look great, do work on your handwriting if it is not too good. Take some tips from good students of your class about the presentations of the answer sheet. Also, take advice from your teachers. Teachers will tell you the best about this scenario because some of them have experience in checking the answer sheets. 
Underlining the important phrases in your answer sheet, making boxes around the answer in the case of mathematics are one of the basic elements which should be used in making your answer sheet looks neat and clean. 
This neat and clean FUNDA will add worth up to 10 extra marks in your board exams, so why not work on it? 

7. The Night Just Before the Exam 
Yes, approx. 10% of your marks depends on this night, make a great use of this night, not in the study but in taking rest, making your mind feel relaxed. 
I too have experienced this night in my life, the only thing I remembered today is fear of board exam, that, what will happen tomorrow? How tougher will be the exam? these type of questions was eating my brain. Having that fear, I opened my notes and started revising the important things. No one was there to guide me that what I was doing at that time was totally wrong. 
I have an experience now and I can tell you what should you do that night. 
1. Make yourself forget that tomorrow is your exam, feel free like a bird. 
2. Do not ever try to revise your study stuff, as this is not one night.
3. Sleep earlier as much as possible, and take a long sleep. This will help you to reset your brain and remember the things more accurately at the time of the exam.

 8.Things to Do and Not to Do On Exam Day
 
According to my 8th point you should sleep earlier on the night just before the exam. Take a healthy sleep of 8 hours and get early in the morning. In the morning, open up your study stuff and make a quick revise of all the topics in a brief way. 
Do not let your can dance down, when you something is still to study. let it be, do not ruin all other topics just because of that single thing. 
You have faced 10th board and this makes you an experienced one for board exams. Do you remember that just before the exam was about to start, a number of students were struggling around with their notes, books and another sort of things? maybe you were one of them. 
So, did that struggling just before the exams helped you in any way? No, the answer is an absolute no, moreover, this activity makes more negative effects on marks. So do not ever study just before the exams. 
Leave all your study materials at home and go with a free and relaxed mind. Do not talk about the topics with friends, stand-alone somewhere and wait for the exam to start. All you need to do at this time is to make yourself more con dent and stronger. 

9. During The Exam Time 
First and important, before reading the question paper, feel and pretend that you are well familiar with each and every question and you know how to answer each question present in that question paper. This is self-defense system and works very well. Thinking like this will make you even more positive and you will perform double for sure! 
Ok, now in advanced 15 min, read out each and every question to its root, understand it, make a plan that how you will do that question. Read all the question with same focus, and then make a strategy that which questions will you attempt rest. 
I know that you will be stuck on some questions while reading them in the advanced 15 minutes, and this will make you bit worried. But don’t panic at that moment, let it be, you will nd a way to solve it later, do not struggle with that particular question, give other questions attention too. 
Always attempt 5 marks questions rst, the simple logic says, you cannot do 5 marks questions when there is the shortage of time and you have to nish the paper, but you can easily do 1 marks even 2 marks questions in lesser time. And this is the best practice when dealing with the questions.Do each and every question with the same attention and same focus because each question is important. Use similar writing and formatting throughout the answer sheet. And please do not make your answer sheet look bad in any way, keep using decorating items throughout the answer sheet. 
Always take a pencil and a scale with you, make diagrams whenever possible while attempting the questions, your diagrams will make a great impression on the checkers mind, so make it happen. 
Time means marks, do not spend more time on doing a particular question, here the experience comes in play. More the previous years or sample paper you have solved before, clearer you will become about the time management on each question. 
Be fully prepared with your stuff like pens, pencil, rubber, scale etc. Do not take chances, take everything in double amount, as each and every second is important here. 

10. Don’t Leave The Examination Hall Soon, You Are Not Done Yet. 
You have prepared for board exam for an entire year and the hours of examination time are the last moments of that subjects in 12th class, so do not let them go. Use these hours as much as possible in a good way. 
Don’t be in a hurry to leave the examination hall after completing your exam, wait to the last second of the exam. Cross check your answer sheet twice, thrice and again and again. If you are thinking that you have done everything correct then, you are absolutely wrong. 
Find your silly mistakes and resolve them. Also, add small design elements to make your answer sheet look good. Cross check your 1 mark questions again. 
Add more important lines to the questions carrying more marks, read each and every answer of yours and if you feel any answer uncomfortable then do not hesitate to make it interesting. 

Bonus Tip
 
During the last 3 months just before the board exams, disconnect yourself from every social activity. Disconnecting includes:
1. Put your facebook account on rest for these 3 months.
 2. Pack up your cell phones, and say goodbye to messengers apps like WhatsApp.
 3. Stop attending parties sort of things.
 4. Say goodbye to your friends even the closer one(you can understand what I mean to say) for this time period.
 
Getting more than 90+ percentage in your board exams is not a joke, you really have to work hard and very hard, you must follow each and every tip given above with full focus and enthusiasm. 
And I am sure if you can follow these tips, you can score more than you expected.

best of luck

Graphics Display Devices

Graphics Display Devices

CAD System uses various display devices and these display devices are the primary output devices. these devices are used to display graphical output on the screen to have a better visualization in real time. These devices not only display the image but is also used to interact with the image by adding deleting and modifying graphical entities on the screen. Thus due to interaction the graphics system are different from the passive graphic system, as in case of television. The Graphics System are classified into the following types

• monitors

• Graphic Plotter

• Printer

Monitors

Monitors, commonly called as Visual Display Unit (VDU), are the main output device of a computer. It forms images from tiny dots, called pixels that are arranged in a rectangular form. The sharpness of the image depends upon the number of pixels.

There are two kinds of viewing screen used for monitors.

• Cathode-Ray Tube (CRT)
• Flat- Panel Display

Cathode-Ray Tube (CRT) Monitor

The CRT display is made up of small picture elements called pixels. The smaller the pixels, the better the image clarity, or resolution. It takes more than one illuminated pixel to form whole character, such as the letter ‘e’ in the word help.

A finite number of characters can be displayed on a screen at once. The screen can be divided into a series of character boxes - fixed location on the screen where a standard character can be placed. Most screens are capable of displaying 80 characters of data horizontally and 25 lines vertically. 

There are some disadvantages of CRT:

• Large in Size
• High power consumption

Flat-Panel Display Monitor

The flat-panel display refers to a class of video devices that have reduced volume, weight and power requirement in comparison to the CRT. You can hang them on walls or wear them on your wrists. Current uses of flat-panel displays include calculators, video games, monitors, laptop computer, graphics display.

The flat-panel display is divided into two categories:

• Emissive Displays - The emissive displays are devices that convert electrical energy into light. Example are plasma panel and LED(Light-Emitting Diodes).
• Non-Emissive Displays - The Non-emissive displays use optical effects to convert sunlight or light from some other source into graphics patterns. Example is LCD(Liquid-Crystal Device)

Printers

Printer is an output device, which is used to print information on paper.

There are two types of printers:

• Impact Printers
• Non-Impact Printers

Impact Printers

The impact printers print the characters by striking them on the ribbon which is then pressed on the paper.

Characteristics of Impact Printers are the following:

• Very low consumable costs
• Very noisy
• Useful for bulk printing due to low cost
• There is physical contact with the paper to produce an image

These printers are of two types

• Character printers
• Line printers

Character Printers

Character printers are the printers which print one character at a time.

These are further divided into two types:

• Dot Matrix Printer(DMP)
• Daisy Wheel

DOT MATRIX PRINTER

In the market one of the most popular printers is Dot Matrix Printer. These printers are popular because of their ease of printing and economical price. Each character printed is in form of pattern of dots and head consists of a Matrix of Pins of size (5*7, 7*9, 9*7 or 9*9) which come out to form a character that is why it is called Dot Matrix Printer.

Advantages

• Inexpensive
• Widely Used
• Other language characters can be printed

Disadvantages

• Slow Speed
• Poor Quality

DAISY WHEEL

Head is lying on a wheel and pins corresponding to characters are like petals of Daisy (flower name) that is why it is called Daisy Wheel Printer. These printers are generally used for word-processing in offices which require a few letters to be sent here and there with very nice quality.

Advantages

• More reliable than DMP
• Better quality
• The fonts of character can be easily changed

Disadvantages

• Slower than DMP
• Noisy
• More expensive than DMP

Line Printers

Line printers are the printers which print one line at a time.

These are of further two types

• Drum Printer
• Chain Printer

DRUM PRINTER

This printer is like a drum in shape so it is called drum printer. The surface of drum is divided into number of tracks. Total tracks are equal to size of paper i.e. for a paper width of 132 characters, drum will have 132 tracks. A character set is embossed on track. The different character sets available in the market are 48 character set, 64 and 96 characters set. One rotation of drum prints one line. Drum printers are fast in speed and can print 300 to 2000 lines per minute.

Advantages

• Very high speed

Disadvantages

• Very expensive
• Characters fonts cannot be changed

CHAIN PRINTER

In this printer, chain of character sets are used so it is called Chain Printer. A standard character set may have 48, 64, or 96 characters.

Advantages

• Character fonts can easily be changed.
• Different languages can be used with the same printer.

Disadvantages

• Noisy

Non-impact Printers

Non-impact printers print the characters without using ribbon. These printers print a complete page at a time so they are also called as Page Printers.

These printers are of two types

• Laser Printers
• Inkjet Printers

Characteristics of Non-impact Printers

• Faster than impact printers.
• They are not noisy.
• High quality.
• Support many fonts and different character size.

Laser Printers

These are non-impact page printers. They use laser lights to produce the dots needed to form the characters to be printed on a page.

ADVANTAGES

• Very high speed
• Very high quality output
• Give good graphics quality
• Support many fonts and different character size

DISADVANTAGES

• Expensive.
• Cannot be used to produce multiple copies of a document in a single printing.

Inkjet Printers

Inkjet printers are non-impact character printers based on a relatively new technology. They print characters by spraying small drops of ink onto paper. Inkjet printers produce high quality output with presentable features.

They make less noise because no hammering is done and these have many styles of printing modes available. Colour printing is also possible. Some models of Inkjet printers can produce multiple copies of printing also.

ADVANTAGES

• High quality printing
• More reliable

DISADVANTAGES

• Expensive as cost per page is high
• Slow as compared to laser printer

10 Tips To Face An Interview For The First Time

1. Know The Company

This goes without saying! This is what any employer expects from you and they aren’t not wrong! Research well about the company you are applying for and know their aim, mission, vision, values and functions. Using this information in your answers will create the right impression in front of your employer.

2. The Introduction

‘Tell me about yourself’ is every employers favorite question! You can read the best reply to this answer here

3. What Can You Offer?

Thoroughly know the job title you are applying for, the responsibilities and why you are fit for the job. For every point that you make, try to have an instance where you have used that quality.

4. Act Confident

This can be quite a task considering it’s the first time you are sitting for an interview but you have to pull off this lie. You have to act confident and make the employer feel that you have it all together and perfectly fit the job.

5. Never Lie In Your Resume

Lying can backfire! The person sitting in front of you has ample experience of interviews and can easily know when you are faking it. So keep it real and only write in your CV, what you have actually achieved.

6. Dress Well

No one can stress enough on the fact that in case of an interview, ‘The first impression is the last impression.’ Put on your best clothes (formal of course!) and look neat when going for an interview for the first time or otherwise.

7. Have Your Questions Ready

Be observant and notice what’s going around you. Once the interviewer is done asking you questions, it is going to be your turn. Return the favor! Ask if you have any questions about the company, the role they are offering you the job for et al. Just make sure they don’t come across as offensive or rude.

8. Be Eager To Learn

It’s okay to not know everything! If you get stuck on some questions and don’t know what to say, politely let the interviewer know. But also make it a point to ask what the answer was once they are done with all the questions. This shows your eagerness to learn, which is often considered useful from an employer point of view.

9. Breathe

More than anything else, it’s the anxiety that ruins most interviews. Just before entering the room, take a few deep breaths and relax your nerves. It always helps!

10. Thank You Mail

Whether or not you are hired, make sure you send the employer a thank you mail after the interview telling them how you are glad you got this opportunity and how you hope you are selected for the same.

So get going! All the best!
