GATE Previous Year Original Question Papers of CSE & IT

Download GATE Previous Year Original Question Papers of CSE & IT easily without any registration or login. Download some of the previous years question papers as it is. These Papers are not modified in any way. Here, we would like to help our readers and others by providing the previous year papers of Computer Science & Information Technology so that they can secure more in their examinations and they came to know about the patterns of their we are providing the offline question papers of GATE held in 2012 and 2013.

Tips Regarding GATE from GATE Toppers:-

1).Getting good score in gate doesn’t depend on which book you follow. Study the books that you have been studying since 2nd year.

2).For securing good rank in gate you must have constant practice on the problems and always stay in touch with gate study.

3).Read and understand the question completely ,understand what is given and what is asked for.

4).Look at the answer choices and eliminate ones that are obviously wrong.

5).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.

6).You must have Good technical knowledge,good understanding of Basic Concepts, ability to apply the knowledge and concepts on variety of problems.
