GATE 2012 Preparation Guide

I would like to represent a first GATE preparation to support with all the information needed for a student to crack GATE apart from technical guide. Covers almost all the topics and lead the whole guide till last minutes to the GATE exam. I hope that will help to many students to find right information and motivation in one place.

It will cover many topics needed for students to understand GATE exam and M.Tech admissions. 

This Guide will include the following topics and more topics will be added as and then information available. To get a motivational letter and information updates I would recommend every reader to subscribe by email. 

GATE Study Material

For some subjects there are multiple books, don’t get confused which one to start. The best book to start with is the book you read before during academic year. It will save your time to learn the concepts as you are already know and if you have any doubts you can refer to the other books. Best thing is to have an own book and other book either can be borrowed from library or from other friend.

I will try to compile one subject study material everyday and I hope to finish few subjects during this week.
