The purpose of the GRE is to test a student's basic verbal and quantitative aptitude, along with his/her writing skills.
GRE Exam Format :
The duration of the test is two-and-a-half hour. It is an internet based test (fully computerized).
There are Three Sections : Essay Quantitative Verbal
Except for the essay section, all questions are objective, with five options as the answer choices. Your total test score will be evaluated out of 1,600 and your essay will be graded on a decimal grade of 6. Quantitative and Verbal sections are of 800 marks each.
Requisites On D-Day : You need to carry your Passport and the Confirmation mail's print out on the day of exam., rest everything you need will be provided at the examination centre.
-> It is not necessary to use flowery language in your essay, be grammatically correct and sound in your sentence construction. Be clear and logical in your thought flow.
-> Do not get nervous, you will not be able to think well so try to relax and think in a calm and clear manner.
-> You will be asked to write two essays, the time given for one of them is half hour and 45 minutes for the other.
This section carries 28 questions and has a time limit of 45 minutes. Most people easily get a score of 750+ in this section.
-> Make sure that the first seven to 10 questions are correct. Spend more time over these questions, as they can really boost your score.
Make use of the rough sheets given to you for performing calculations.
-> Imp : For questions on Statistics and Geometry, note that the figures drawn may not be to scale, so do not use them as a reference. Read the numbers and their units carefully, at times, they mislead you on purpose.
-> In algebra questions, verify all answer choices. Do not just mark the answer choice you work out. This is because, at times, you may be faced with similar answer choices that could easily be misleading, so make sure to choose the perfect choice for the question. That means you need to read each question thoroughly before answering.
This section is a 30-minute section with 30 questions. Most students find it tough to score in this section, however with sufficient preparations, nothing is impossible.
You will find the following question types in this section:
-> Concentrate on the reading comprehension passages. They will mostly be dull and tedious to read, so it is advisable that you start practicing by reading at least 4 passages per day. You will have to improve your speed of reading in order to fare well in this type of question.
-> The easier questions to handle are the antonyms, sentence completions and the analogies. You will need to be well versed with the GRE word list. Just mugging up lot no. of words in Barron's alone won't help you. Even if you end up studying 3000 words give or take 500, I'm sure, half the words you face on the day of exam will be newer ones. So, the tips and tricks are the one's that will give you a desicive edge.
Some Basic Tips are,
-> Studying words in groups(those having similar meanings) is much more simpler, than to learn words in isolation(Barron's format).
-> Knowing how to eliminate the wrong choices.
-> Root meanings and lot more.
For instance, knowing the given word has negative or positive meaning alone can eliminate three choices out of five. So the probability of getting the right answer is more. Refer to books like Barron's and Kaplan(Much better book for Verbal) to learn strategies on tackling these questions.
-> Most students taking the GRE find the verbal section a bit lengthy. So take enough practice tests to develop speed.
-> The test is adaptive in nature. The first question the computer throws at you in a section will be of average difficulty. Half the people taking the GRE get it right, which generally means it is fairly simple.
If you click on the correct option, the next question on your screen will be slightly more difficult. If you get the first question wrong, the next will be easier. This adaptive nature of the questions continues throughout the test. Thus question's toughness increases as you get the answers correctly every single time. This way, ETS makes sure you can't get lucky all the time, throughout the exam. It is your job to get to these hard questions as quickly as possible. Because, getting a hard question right will help you score a lot, but if you get it wrong, it will not affect your score drastically.
-> The questions in the test have a Descending Marking Scheme. After around seven to 10 questions, the computer fixes a difficulty level depending on your answers in the previous questions. The higher the difficulty level, the stronger your chances of achieving a high score.
-> The first question carries maximum marks, followed closely by the second, then the third, and so on. In short, the final couple of questions are of little or no significance to your final score in the section. The first seven to 10 questions are absolutely vital. Your section score range will be decided by your performance in these questions. So do take some time and make sure to answer them right.
For example, if the first eight questions I attempt are correct, my score will oscillate between, say, 700 to 800. If I get a couple of questions incorrect in the first eight, my score may range from 550 to 750, though I will need a super performance in the remaining questions to get a score of 750 or above.
The questions after the first 10 are basically to decide where your exact score lies in the score range decided by your previous 10 attempts.
-> So take ample time cracking the first 7-10 questions, even if you miss out on five questions at the end.
GRE does not have negative scoring, so remember to click away the last few questions, when you run out of time.
What are level-triggered and edge-triggered interrupts?
-> A level-triggered interrupt is a class of interrupts where the presence of an unserviced interrupt is indicated by a high level (1), or low level (0), of the interrupt request line.
-> An edge-triggered interrupt is a class of interrupts that are signaled by a level transition on the interrupt line, either a falling edge (1 to 0) or a rising edge (0 to 1).

Guys from my point of view, there are two major reasons that accounts for the answer....
-> When we turn on the switch., a large amount of current starts to flow.. So it becomes highly necessary for us to ground it immediately. The top most pin(also called earth hole) serves this purpose.
-> The reason why it is big - The property of the current is that it takes low resistance path. As the resistance is inversely proportional to the area of cross section(from the formula: R = P*l/A), the earth hole's bigger size serves as the low resistance path for the large initial current flow.

Cast : Edward Norton, Liv Tyler, Tim Roth. Director : Louis Leterrier.
This is the kind of movie that you could safely watch with your brain left back at home and still understand every bit of the whole story. That's simply becoz of the predictable storyline. There is nothin new with this sequel of HULK, except for some really good action sequences(three of them to be precise). The movie tries really hard to keep you engrossed for itz duration of 90 mts., however it fails pathetically in the end...
I think that hollywood has churned out quite a few superhero movies of this kind., and what's so very treacherous is that., the director has not even cared to make any changes to the stereotypical storyline... The military is in hot pursuit of HULK and try to capture him and as usual... their efforts go in vain... so they use one of their own men(whose been injected with certain super-fluids to make him super human) and it subsequently culminates into the climax fight between the two(Good Vs Bad) and you know the result...
Word of Caution: More action packed than previous Hulk movie.. Nothing much!!
What is the basic difference between Electrical and Electronics Engineering???
Guys this question was asked to me in TCS interview.
Actually, there are two major differences that account for the answer.
-> First and foremost is.., Electrical deals with or say, is worked with high voltage(> 1V) & low frequency(As in 230V,50Hz) and Electronics deals with low voltage(<> And the second difference is, Electrical deals with electron motion only and Electronics deals with electron motion as well as other characteristics or properties of an electron.

For Numerical Methods..., All that you need is a calculator!! Easiest subject in any list and you need only two or at the maximum three days of preparation. Every unit will have a set of five to six model or types of problems and every type has a equation to solve. All that u got to do is remember the equations of all the types and make sure you solve atleast one problem in each type. This will make sure you don't get confused while exam time. Unit five will be a little bit different and comparatively tough coz the problems in it are lenghty and bit complex too.. This unit will require more efforts from you to understand.
-> Regarding the text books, Your class notes will be the best ones for sure. So better get a good hand written notes form your class padips (((:P))). you'll need text book for the fifth unit(rest is optional). We people studied Kandaswamy for that unit. Specifically, Singaravelu was not recommended for us as it had many mistakes in printing. For the first four units, if you don't manage a good notes, you can go through Balaji book with kandaswamy as reference.
This subject will give you much space to study other subjects during study hols. It is quite easy, for sure. All that you got to do is write down formula papers, peruse them frequently, go through the solutions for each type and make sure you have solved problems in each type atleast once.
Guys we had Television engineering and High speed networks as our electives. No doubts!! Television engineering is the worst elective to prefer. If you have the choice, avoid it. HSN is vast but manageable and quite easy too.
For Television Engineering…, you have to buy two books of Gulati. Monochrome and modern television. These two books will cover whole of the syllabus. The VAST ever syllabus in electronics and comm. Engineering…,you’ll find in this subject. 1st and 3rd unit(first half’s in both) will be very interesting as they cover the basics of TV working. Rest chapters will give you worst nightmares. (If this review was full negative, let me also let u know., I second topped TV in my batch(in boys ofcrz, gals are jobless!!))
For High Speed Networks…, There’s only one book – William Stallings. This book is sufficient. The only point is every single topic in your syllabus will be given for 8 - 10 pages in the text book. But the no. of topics is less. Jus learn to fill four to five pages in your answer sheet for each of the topics in the syllabus. That will do.
Other electives – Some of my friends in other colleges had Digital image processing(DIP). I personally don’t have much knowledge about the subject but one thing I can assure you is, you’ll get a minimum of 5 to one week period of time before the exam day.So this should give you the picture. You’ll have all the time to prepare your other subjects in study holidays and finally u can sit for DIP. The other elective that I have some knowledge about is Internet and Java. For this subject you don’t have proper textbooks same as VLSI. All reference books are only available. This subject is divided into two parts – Internet which is similar to our comp networks(one of the easiest subject we’ve come across) and Java part is tough generally and also with no proper material.
Guys we found TV to be the toughest subject out of all.. The rest all should work wonders for you people. Regarding any feedback you need on a book before buying/ using it…, u can always ask over here(in the comments section). Will give you people the best guidance possible from me. All the best!!!
I, me, myself.. yet to discover. Love to talk a lot( if somebodyz listening :D) - better of listening to people talking.. I'm a firm beliver of my ownself.
