DISCLAIMER: All the information contained in this page is completely my opinion neither the institute nor the GATE committe has nothing to do with this. Iam not responsible for any wrong or misleading information contained in this . 1) which books should be followed for GATE preparation? GATE questions are concept oriented so regardless of which books u follow you should get through knowledge of subject. My suggestion is that u better follow ur text books like ullmaan for computer theory, Galvino or stallings for operating systems, navathe or rrk for dbms and forouzan for n/ws etc...it's always preferable to read atleast 2 books on each subject. 2)Do GATE questions asked from previous question paper or any books or they are constructed newly every year. They will be constructed newly every year. There is some possibility that some questions will come with some changes from old. 3)Which objective or reference books are worth to follow, even have fewer errors? you can go through timothy j. williams, G.K. publishers(its full of errors) 4)Which topic should we should give preference? Automata,Graph theory,mathematics,Data structures,Operating systems 5)How to apply for IISC Bangalore? IISc calls for admission in feb 1 week and the last date will be around mar15 (mostly 3 or 4 days after mar 15) 6)How much percentile do I need to score? For getting into IISc your percentile should be 99.8-99.99 7)How much question one needs to score to get into iisc? you must attempt atleast 100+marks if the paper is hard and atleast 140 if easy. 8)Do you have any information how much a person should score to get into one of these prestigious colleges like iisc, iits, etc. For iits direct admission you must get 50-200 rank(General category) depending on IIT. you will get iit even upto 98% provided you performs well in written test or interview 9)Do you have any information regarding getting admission into Mtech without gate percentile? Or they hold different exam for their admission. its not possible for IITs and IIScs except through sponsorship or QIP. 10) Do you have any idea about this year GATE paper look like? that's we can't tell 11) If you think this topics are prepared from this book only or one should refer this books to get hold of this topic please suggest me nothing is like that
