Basic GRE Know How??

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 :



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.

Essay Section

-> 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.

Quantitative Section

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.

Verbal Section

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:

1. Reading comprehension passages
2. Analogies
3. Antonyms
4. Sentence completion

-> 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.

GRE - How It Works??

-> 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.

32 Bit Thinking.... # 3

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).

More answers for the question are welcome in the comments section.
