GATE CS · Work through your exam, one topic at a time.

GATE 2026 is the Graduate Aptitude Test in Engineering, a national-level examination that assesses candidates' understanding of undergraduate-level subjects in engineering, technology, science, architecture and humanities. The organising institute for GATE 2026 is IIT Guwahati, conducting the exam in collaboration with IISc Bengaluru and the other IITs on behalf of the National Coordination Board, Department of Higher Education, Ministry of Education. The Computer Science and Information Technology (CS) test paper is one of 30 test papers offered, comprising full and sectional papers. A candidate may appear for one or two test papers, but only selected two-paper combinations are permitted. Qualifying opens admission, with possible financial assistance, to Master's, direct doctoral and doctoral programmes, and some colleges and institutions use the score for postgraduate admission without MoE scholarship; several PSUs use GATE scores for recruitment, with NIC listed as using CS, EC and DA results. The score remains valid for three years from the date of result announcement. Topics on this exam: Computer Science and Information Technology (CS). The GATE CS study guide has 1 section and about 482 words.

GATE Computer Science and Information Technology (CS): Scoring the Core

GATE CS is one three-hour computer-based paper of 65 questions and 100 marks. General Aptitude supplies 15 marks; the Computer Science and Information Technology portion supplies 85, and roughly 25 questions are worth 1 mark while 30 are worth 2. The syllabus runs across Engineering Mathematics, Digital Logic, Computer Organization and Architecture, Programming and Data Structures, Algorithms, Theory of Computation, Compiler Design, Operating Systems, Databases, and Computer Networks. Most marks are won by exact computation and precise definitions, not by broad recall.

  • Practice questionsIn the standard TCP/IP model as used in GATE, which layer is responsible for end-to-end reliable delivery and flow control between processes on different hosts?
  • FlashcardsMaster theorem case 2. For T(n) = aT(n/b) + f(n), if f(n) = Θ(n^(log b a)), then T(n) = Θ(n^(log b a) · log n).
  • Cheat sheetAsymptotics: if lim f/g = c with 0 < c < ∞ then f = Θ(g); c = 0 gives f = O(g) and f = o(g); c = ∞ gives f = ω(g).
  • Key termsAsymptotic complexity. A description of how an algorithm's running time or memory grows as input size increases, ignoring constant factors and lower-order terms.
  • Study planDerive and memorize the master theorem cases and apply them to at least 15 recurrences.
  • Common mistakesThe paper is not ordered by difficulty, and the first half mixes easy 1-mark items with genuinely hard 2-mark ones.
