Hastagiri Prakash

For all GATE aspirants, learning the basics is the key to a good score but with high probability, there would be a few questions which we cannot solve completely with the preparation we have already had. for questions like this, do not panic or leave the question unanswered by default. I would recommend the following strategy:

1. read and understand the question completely. understand what is given and what is asked for.

2. try to make some headway with this information. for instance you dont remember or know a formula but know that the answer is directly proportional to something or inversely proportional to something else. try to formalize this partial knowledge in a helpful way

2. look at the answer choices and eliminate ones that are obviously wrong

3. look for patterns in the choices. sometimes, the choice that sticks out the most is probably a wrong choice. sometimes, all the choices contain the same variables but in different positions (numerator, denominator, exponent, log etc)

4. using any of the heuristic, if you have narrowed down the choices, then guess.

i repeat, this is to be used as a last resort and not as an excuse for not preparing but you will be surprised at how many questions you can answer if you follow this. This way of answering is dangerous and is an art. this art can be honed only attempting many practice questions of multiple choice types and not by just reading the theory.

Getting good score in gate doesnt depend on which book u follow. Study the books that u have been studying since 2nd year. I didnt even have books on mathematics, s/w engg and web tech. Study the books that u are most comfortable in .

For securing good rank in gate u must have constant practice on the problems and always stay in touch with gate study. For that purpose u can join any coaching inst(like gateforum). There u will be in constant practice. I studied in gatefoum. Also u must solve previous year gate questions and MUST take some all india test series (normally starting from october)..

I dont visit this community(and orkut) often. Use the links that i gave in my websites. I have specific filters set up for that purpose(Dont email me directly). so u guys will get replies quickly.

I can tell u the books i followed :-

1) Maths :- No books.. gateforum notes enough

2) TOC :- No books.. gateforum notes enough

3) OS- Galvin

4) CO- Hamacher (Very good book)

5) Digital logic : – No books.. gateforum notes enough

6) Networking :- william stallings and foruzan(Stallings- numericals , foruzan- theory)

7)DBMS :- Korth

8) Data structure :- Tanenbum

9) Algorithm :- Cormen

10) Web tech :- Internet

11) S/w Engg – Gateforum book and pressman

12)Compilers :- No books.. gateforum notes enough (Recommended book is Aho ullman)

But follow the books that u are most comfortable in.

**Subject Wise Books to follow**

To become GATE topper, you need

1>>Good technical knowledge

2>>Good understanding of Basic Concepts

3>>Ability to apply the knowledge and concepts on variety of problems

To Develop 1 and 2 you will need to read and understand reference

books, to develop 3 you will need to solve the problems. Now question is from where to get the problems or the MCQs, the answer is the problems are given at the back of every chapter in the reference books, you will need to solve those problems,may be not all of them. Problems reveal lot of truth and clear our misconception and false convictions. And GATE has certain property that lot of Questions in it are based on concepts that are revealed in certain problems in reference books. So its really really important to have a shot at the problems.

**DISCRETE MATHEMATICS**

I started my preparation with discrete maths, and I would recommend you also to start with this perticular subject because this is the subject from where Computer Science spreads out. Understanding of this subject is very important. I used following books:

1>>”Discrete maths and its applications” By Kenneth Rosen

This is an excellent book for GATE preps. Lot of problems are given at the end of every chapter plus answers are also given to odd numbered exercises. The explaination in this book is really very good and “easy to understand”. This book is must read for GATE preps.

2>>book by Tremblay and Manohar

I recommend you to read this book after you have read Rosen’s book. The contents in this book is hard to comprehend. You need to have your basics cleared before you attempt this book. This book is also a “must read”. I also have the lecture notes on discrete maths from some prof at McGuire university the advanced counting and recurrence relation part is good.

**ALGORITHMS**

I recommend to you to read this subject along with Discrete maths or after you have completed discrete maths. I used only one book for this

subject and found that to be more than enough for GATE.

1>>”Introduction to Algorithms” By T.H.Cormen et al.

This is “THE” book for Algorithms. The Book is simply brilliant, it makes you understand every details of Algorithms. So this book is a must read. Although I did not read the entire thing. Here is the list of chapters that I had read. If you are interested of course you can read the entire book.

Chapter 1,2,3,4[excluding 4.4],6,7[excluding 7.3],8,10,11[excluding 11.5],12[excluding 12.4],18,22,23,24[excluding 24.4 and 24.5] for NP-Completeness you can read 34 also. In addition to this book I strongly recommend you to see the video lectures from MIT. The lectures are given by

Lieserson[who BTW is also one of the authors of CLRS] and Erik demaine. The

lectures are absolutely brilliant. You may download them from Free Online Course Materials

**DATASTRUCTURES**

I did not read this subject exclusively. I mostly participated in discussions in Algorithms and datastructures communities on orkut . That is i think more than enough.

**• THEORETICAL COMPUTER SCIENCE**

I initially tried to decipher Ullman’s book but I found the content too much for my brain to comprehend. So I switched to “Introduction toComputer Theory” By Daniel Cohen. The

contents in this book are lucid. Also solving or atleast attempting the problems in

the exercises is a must. But its really great if you could read Ullman.

**• DATABASE MANAGEMENT SYSTEMS**

I used Korth and Navathe for this. Initially I read korth because it is lucid and then only for normalization i read Navathe. The database design part in korth is difficult so read this part with utmost concentration and you may require several readings before you begin to understand things.

**OPERATING SYSTEMS**

Read this from following books:

1>>Operating System Concepts By Galvin et al.

2>>Stallings

Attempt problems in Stallings they are very important especially problems on memory management and virtual memory. In Galvin the theory on memory management is excellent.

• Digital Design

Read “Digital Design” By morris mano [period].•

**COMPUTER ARCHITECTURE**

Read this from following books

1>>”Computer Architecture” By Morris mano

2>>”Computer Organization” By Zacky,hamacher

3>>”Computer Organization Hardware/Software Interface” By

Hennessey and Patterson

Read book 1 almost completely then read memory system from book 2 then

you can read

book 3, I had read only the performance measurement chapter from book

3 as it is not given in any other book and also solve numericals fromexercises they are

very very important. I recommend you to read this

subject after “Digital Design”.

**• COMPUTER NETWORKS**

I had read this subject only from forouzan and had read some chapters from Comer’s book. Attempt the exercises from forouzan they are

important.

• C programming

You read this from “the C programming language” by kernighan and Ritchie that is more than enough plus spend some time in actually

programming in C that is the best way you can learn C.

• C++

I dont know C++ much and I did not read anything for C++. Dont be spoiled, you can read C++ complete reference if

you wish to.

**Compiler Design**

“People” say Ullman’s book is excellent so you can read it from Ullman if you believe “People”. In the final phase of your preps “try” to solve GATE papers. The answers for the GATE papers are not present anywhere but still you should attempt them anyway. This will give youconfidence that you can actually solve GATE. You can read all the subjects given here you can skip one or two if you dont have much time But more important thing is to “MASTER”atleast 2 or 3 subjects. Also actively participate in discussions at GATE CS or GATE CS/IT 2009 and Algorithms and Datastructures community in orkut – that helps alot in patching few loopholes in our concepts

and enhancing your problem solving skills. Thats it guys,this much is I think enough to crack GATE. You can ofcourse

Device your own methodsand set of books. Just be confident you can do it!
