s ask should I go for gate forum ,brilliance or other coaching institutes study material or should I follow the standard books.GATE requires you to have a deep understanding of subjects ,coaching material gives a highlight of important topics and provided you some questions. I feel that it better to go for standard books than coaching institutes material . Because if you look at the history of GATE you will find that 95% of questions are from standard books.Most of these question are from the unsolved exercises which are given at the end of each chapter.Which we usually don’t solve or its better to say that most of us even don’t look it .Here I am presenting a list of standard books recommended by GATE gurus for CS/IT students .
