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 :

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.

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.

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).

Why the top most pin, biggest in a plug point??


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.

Hulk 2 - Isn't that Incredible!!!

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!!

32 Bit Thinking... Ques 1

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.

5th Sem - Numerical methods!!

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.

7th Sem - Electives

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!!!

7th Semester

This post is for many of 'em who are not aware or confused with what books to use for the 7th semester subjects, ECE. At this point most of you should be placed & others seriously trying but ultimately study leave is the only time you would want to touch the books again!.. Most colleges start bugging you people with final year projects in 7th sem itself. So., I have given a more detailed version, for each of the subjects which will also let you know where to start and similar things. Here it goes then...

For Optical Communication..., The only book available is Gerd Keiser. This subject may seem too easy to start with, in the study holidays. The theory content in it., is understandable and its quite like any other easy subjects that you would have come across. Before you get too happy.., there is a surprise… This subject has a lot of equations. The much worse thing is.. all of them are final conclusive equations based on some scientist’s story. It’ll be something like – In 1914 this person and his team were able to conclude this topic from nowhere and the equations based on their theory are as follows.. And the equations that follow will be ‘Greeks and Latin’. Sigh!!

-> If you are looking for a local author – there’s Anuradha publications. The author name is Arumugam(Not sure). Which will be of NO use at all, for sure. All answers are cut short from Keiser and are too short to elicit in exams.

So in total.., the examiners will expect you to write the equations, diagrams and some theory scribbled in between. In terms of the chapters., Chap 1 is too easy guys. It only consist all the stuff we already know. Topics as simple as single index fiber, graded index etc. Next, Chap 4., everybody would like this chapter for sure. More theory, few equations, interesting stuff too. Chap 5 is also a good and easy-one comparatively. You’ll have problems with Chap 2 and 3. Chap 2 – too many equations and few Imp topics I remember are material and waveguide dispersion. Pulse broadening topic(a one which everybody tends to avoid) has been asked in the previous years. So., the choice is yours. First half of Chap 3 is easy constituting LEDs., and the second part is a bit vague and lengthy one containing the LASER’s.. though few topics will be easy.

-> Bottom line – We guys thought this to be a easy subject but it ended up to be a nightmare before the day of exam due to lot of equations to mug up. To sum it up… Can be cleared easily.. No doubts!!! It’ll just give you a head-ache.


For Microwave Engineering…, For the first four units you got to refer Samuel Liao and for the fifth unit, its Annapurna Das. There’s no good Local Author. For us, our Mam notes was too good… Actually, it was fully copied from Liao, but the positive thing is, it contained only what was necessary. Fifth unit is kind of easy.. as in., the answers will be repetitive for consecutive topics with only few changes in between.

Guys., don’t get afraid with the big syllabus. Its actually like, they have given the sub headings as well.. So it is just like any other subject. Unit 3 will be repeated twice in some of the copies(syllabus). The interpretation is just this – the second unit topics as in the syllabus copy is elaborated with their subtopics in the first Unit 3 section. And the actual Unit 3 is given in the Second unit 3 section. Unit 3 starts from Klystron topic and the rest all belongs to unit 2.

-> Bottom line – Few juicy topics will keep you alive through out. Don’t conclude the subject to be lengthy from seeing the syllabus. In all… a easy subject.


For TQM…, buy anything guys... its jus stories... We referred Vijayakumar(Not sure of the name). All you need to know is diagrams and the Sub-headings in each topic. Inside story, script, direction everything is yours!!


For VLSI…, The only subject for which I never knew which book I studied, in my whole of engineering. The point is there is no specific book at all for this subject. The ref books given in syllabus also doesn’t contain all that you want. Nothing in no text book will be continuous. All we had was lot of Xerox copies, unknown from which text book it was.

-> You should buy the local author book Rekha., which will be of use to you for studying the topics that isn’t covered or not clear in all of your Xerox copies. Imp point is don’t study everything from this just because it covers most part of the syllabus. All of them are too small answers compared to what is required.

We people had Xerox copies from the start., but no one clear of what to study.., so all of us happened to study in the last few ending days of study leave. And also, fortunately, it was the second exam for us next to TQM. So we were able to allot last four or five days for this alone.

-> Bottom Line – Easiest subject of the lot(very few hard topics & most units are very small)… if you succeed in getting the right Xerox material.

*Where to get the Xerox?? You can get all the text books & references given in your syllabus(there are three to four) from your professors and compare them with the syllabus, get them Xeroxed to what u want. Buying books for your own is a bad idea coz each book will have only twenty to twenty-five pages covering our syllabus.


7th Sem electives to follow in the following post!

5th Semester

This post is for many of 'em who are not aware or confused with what books to use for the 5th semester subjects. I'm really glad to be a part of -helping you all ppl- with the guidance that I can offer here through this blog... This semester is the most interesting one out of all the eight semesters duly because of the ‘Micro-processor’ factor. All the subjects are our core ones(post education pt. of view, unlike prev sems.). Here it goes then...

For Microprocessors..., buy Manohar... it is one of the most awesome book I’ve ever read. You can also buy Goankar(For 8085). If you are finding other books difficult to understand, first read from Manohar..., then see these books.. It’ll be more easier for you to understand then. 8085 should be known every nooks and corner, as it forms the basics for all the other topics(86 & 51).

-> If you are looking for local author buy Manohar & keep bakshi as reference. Though you'll always have to go through other books Goankar(8085) and Masdi(8051 - Ctrlr), Just to make sure you are good with the topics or say you know it wholesome.

I used Manohar and I also had Bakshi(use it very less-preferable) for reference along with Goankar. I personally didn't use Masdi coz I came to know of the book very lately. Goankar and Masdi will have contents too vast compared to what you require as per syllabus. So use them carefully.

For DSP..., there's only one book..., Ramesh Babu... You gotta buy it., but you can also try and get good hand written notes(optional though). The notes can be really very useful... even if u don't get the notes..., Ramesh Babu will be sufficient. Btw., for the fifth unit which contains DSP processors, you'll have to get it from another book(Venkataramani). Most staffs will tell this subject is very tough and all, as in ‘degree stopping paper’ – Bull shit!, it isn’t that tough TRUST ME!!!.

For Ctrl Sys..., You have only one book Nagoorkani... DON’T BUY ANY OTHER BOOK. This one book alone is damn sufficient. Very very easy subject in terms of preparing the day before exam, as far as you know to draw all the graphs... quite easy they are...

For Ethics…, buy anything guys... its jus stories...

For Communication Theory..., buy a book called Jabeena(Charulatha Publications)... actually prescribed book is Simon Haykins... this book is one of the foreign author books that I liked a lot. There is one drawback in Simon Haykins, that is.. its difficult to find the prescribed syllabus in Simon Haykins. This Jabeena book is jus the exact photocopy of Simon Haykins(with no letters even changed) and only our exact syllabus will be given. Better buy both. Study from Jabeena and keep Simon as jus reference. DONT BUY BAKSHI. All answers are given so short in Bakshi. So if u read from it completely, you may end-up flunking in the subject. Simon Haykin alias Jabeena is very easy and you'll understand everything clearly.

-> If you are looking for local author…, Jabeena is definitely the best book.

For Transmission Lines..., buy 2 books... one is Bakshi..., and the other one is Dananjayan of Charulatha Publications... You'll have to use ‘both the books very equivalently’. Don't stick to one book. Thers Smith chart(graph based question) – sure question, learn it well and you can score easily on this one.

Guys we found Communication Theory to be the difficult subject, but thats only coz, we didn't find the proper book at all(almost till the end)... So don't give a heck to anyone..., jus buy the book I had mentioned above and start reading.. esp. JABEENA +vely. Don't worry at any point... see, for example you'll have the 3rd (or 4 th- I don’t remember) unit to be only 21 pages in Jabeena. Actually our syllabus is also that only. So don't think something is missing in the book. JUS READ WAT IS GIVEN IN JABEENA FULLY.

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 ppl the best guidance possible from me. All the subjects are easy in 5th sem provided you start with the rite book. So go on… All the best!!!

First Things First!!!

Guys and Gals..., I have come across various blogs and all I can depict from my quick glance at em, is that most of the blogs are created to outpour frustrations, anxiety and other negative traits. Well, they can't be blamed because writing.. soothes and at least if you can't punch your boss in his face, you can write shit about him in your blog and expect others to read.
No… I am not here to cripple words for my boss, I don't even want to tell you how psycho is my ex-girl friend, I don’t want to curse the state for not doing well, I don't want to tell you about my first crush...... But if I do anything out of these...please bear with me ...after all I am also one of those species..
I assure you ppl that all of my posts will be not more than 10-15 lines, coz I don’t read article/ views that last more than 10-15 lines and secondly my brain doesn’t work that longer continuously… But really, I just want to write about simple and interesting things... hope you all will like it!!!

My First Post...

Its jus been a month and few days since the final xams got over, but it all seems like its been ages and I already feel so bored, with nothing really to do, but I don't want complain.....Its ok to do nothing....Its fine, completely fine.......

Hopefully my life takes a complete 360 degree turn, with my professional career ahead... Am suddenly feelin all grown up now & to add to it., I'll be interning into god-knows-some IT days of my life.. I just don't want him to make my life hell, maybe I'll make his one!!!!!

Am not really sure wat kinda posts i wanna make in this blog..., but am sure you all ppl will like it. Posts will partly target the techi stuff ie Electronics.. that i like the most and others as well.. Do check regularly and post your valuable comments.

Best regards.
