Updated: Feb 13

APSEd brings you a special analysis of GATE 2022 Environmental Science and Engineering [GATE ES] conducted on 6th Feb. This GATE ES paper was introduced last year and conducted by IIT Kharagpur. A total of 10,000 aspirants were expected to appear in the paper.

If you are an environmental enthusiast and want to pursue it as a career, this paper could open doors for you.


Students had a common opinion on the level of the paper, that it was slightly tough compared to last year, and more MSQs this time;


Overall Analysis of GATE 2022 Environmental Science


GATE 2022 ES paper being introduced for the second time, the only source of information we had to access beforehand were the ES syllabus and sample paper and previous year analysis.

  • The paper had more theoretical questions. A clear understanding of topics was required to attempt the questions. There were a few tricky questions as well.

  • There were more MSQs this time as well, which made the paper tougher. But still, we stressed more on MSQs in our ES tests with about 8 questions in our full-length tests. It turned out to be useful, as the GATE paper had about 13-15 MSQs

  • Aptitude and Mathematics turned out to be easy and direct questions were asked from these subjects.

  • As expected, there were about NATs with 17-19 questions asked, which is in line with the previous year GATE paper and APSEd full-length tests.

Check the below graph for the distribution of questions across MCQs, MSQs, and NATs.

Generally from what we observed in our full-length tests, many students get the MSQs wrong as it is quite tricky. With more MSQs this time, we can expect the cutoff to be a bit lower this time around.


Overall, the paper was moderately tough.
