Last 10 Year question papers and keys of GATE CH

Graduate Aptitude Test in Engineering (GATE) is an examination conducted by the Indian Institute of Science (IISc), Bangalore along with seven Indian Institutes of Technology on behalf of MHRD and Government of India to test the comprehensive understanding of the candidates in various undergraduate subjects related to Science.

GATE Qualification is mandatory for seeking admission to:
(i) Master’s programs in Engineering/ Architecture/ Technology
(ii) Doctoral programs in relevant branches of Science, in the institutions supported by the MHRD and other Government agencies.

The score of GATE Examination is valid for Three Years from the announcement of the results and they are accepted by more than 900+ institutes across India.

A collection of previous years GATE CH Question papers with answers are provided below to give a better understanding about GATE CH upcoming examination.
