The best way is to start solving exercises at the end of chapter. I watched video lectures for 1-2 hours, read for 2 hours and solved for 2-3 hours

GATE CSE Facebook is a community for GATE preparation and many GATE toppers share their experiences. Here is a sample post on Preparation

Computer Science Forum has informative posts on GATE-CS that gate aspirants have stumbled upon.

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 particular subject because this is the subject from where Computer Science spreads out. Understanding of this subject is very important. I used following books:

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 explanation in this book is really very good and "easy to understand". This book is must read for GATE preps.

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.

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

DATA STRUCTURES

I did not read this subject exclusively. I mostly participated in discussions in Algorithms and data structures 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 to Computer 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

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

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 you confidence that you can actually solve GATE. You can read all the subjects given here you can skip one or two if you don't 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 Data structures community in orkut - that helps a lot in patching few loopholes in our concepts and enhancing your problem solving skills.

That's it guys,this much is I think enough to crack GATE. You can of course Devise your own methods and set of books. Just be confident you can do it!

It is the entrance exam at the National level for admission into Masters courses / Direct PhD at different engineering disciplines into any college in India that has a Post graduate programme.

It doesn't guarantee an admission into premier colleges like IIT's but it is a requirement. Most colleges put of advertisements for admission separately.

A student who is GATE qualified gets a stipend of Rs. 12500 per month for a period of 24 months i.e. for the two year that it takes to complete a Masters in Engineering.

This scholarship is applicable for students taking admission to AICTE recognised regional engineering colleges too.

Students have to do 8 hrs / week of Teaching assistantship in return.

1. Candidates who have completed graduation in engineering
2. Candidates who are in final year of engineering

Public sector companies, Government organizations, Research bodies, Group 'A' technical posts.

Applications are invited in month of September and the exam date is on saturdays and sundays of January and February.

Candidate can appear in only 1 paper.

Multiple choice questions and numerical answer i.e no options are both present in the paper.

Negative marks are given for attempting wrong answers. No negative marks are for numerical answer type questions.

Total weightage is 100 marks.

All the papers will have a few questions that test the General Aptitude (Language and Analytical Skills), apart from the core subject of the paper.

In all the papers, there will be a total of 65 questions carrying 100 marks, out of which 10 questions carrying a total of 15 marks will be on General Aptitude (GA).

In the papers bearing the codes AE, AG, BT, CE, CH, CS, EC, EE, IN, ME, MN, MT, PE, PI, TF and XE, the Engineering Mathematics will carry around 15% of the total marks, the General Aptitude section will carry 15% of the total marks and the remaining 70% of the total marks is devoted to the subject of the paper.
