GATE CS Paper Analysis 2021

The CS exam of GATE this year was comparatively easy and the question paper was not that lengthy. Difficult questions were asked from Algorithm, complexity, data structure, and computer organizations. As compared to the previous year, the test paper was not that difficult this year. The NAT questions were lesser as compared to theoretical questions.

  • The difficulty level of the exam was easy to moderate.
  • The General Aptitude section was fairly easy.
  • Questions from the technical section was a little tough.
  • NAT questions were of medium difficulty level.
  • Most of the questions were from the theory of Computation, Operating Systems & Data Structure.
  • Double Hashing, Recurrence, Relation, Worst case, Groups, Graph colouring, Time complexity, Post-order traversal, Predicate Logic, Minimum spanning tree were some other topics in the question paper.
