GATE CY study guide
GATE CY · Work through your exam, one topic at a time.
GATE 2026 is a national-level examination that assesses candidates on undergraduate-level subjects across Engineering, Technology, Science, Commerce, Arts, Architecture and Humanities. It is conducted by IIT Guwahati in collaboration with IISc Bengaluru and the other 22 IITs, on behalf of the National Coordination Board, Department of Higher Education, Ministry of Education, Government of India. The GATE CY study guide has 11 sections and about 3,506 words.
01General Aptitude
General Aptitude carries 10 questions and 15 marks out of 100 - a high return per question, so accuracy here moves the rank as much as any technical section. GATE tests three strands: Verbal Ability (reading comprehension, sentence completion, grammar, vocabulary in context, narrative sequencing), Quantitative Aptitude (ratios, percentages, profit and loss, time–speed–distance, time and work, mensuration, geometry, data interpretation, series) and Analytical Aptitude (seating arrangement, blood relations, syllogisms, deduction, data sufficiency).
346 words, about 2 min02Discrete Mathematics and Engineering Mathematics
This domain supplies roughly 5–7 questions and mixes pure discrete mathematics (logic, sets, relations, combinatorics, graph theory, algebraic structures) with the engineering mathematics GATE expects: linear algebra, calculus and probability. Questions are short but exacting - one wrong quantifier or one forgotten case loses the mark.
336 words, about 2 min03Digital Logic
Digital Logic in GATE covers number representation, Boolean minimisation, combinational building blocks and sequential circuits, usually as 2–4 marks of crisp, verifiable questions. Almost every question is checkable by hand, so the marks come from care rather than insight.
307 words, about 2 min04Computer Organization and Architecture
This domain tests machine-level execution: instruction formats and addressing, datapath and control, pipelining, the memory hierarchy and I/O. Questions are quantitative - cache geometry, speedup, effective access time - so set up the calculation before touching the options.
328 words, about 2 min05Programming and Data Structures
This section mixes C programming semantics with classical data structures. GATE favours short code fragments whose output must be derived by hand, and structural questions about trees, heaps and hashing.
322 words, about 2 min06Algorithms
Algorithms carries the largest single weight in the technical part. It tests asymptotic analysis, recurrence solving, the greedy/divide-and-conquer/dynamic-programming paradigms, and graph algorithms.
310 words, about 2 min07Theory of Computation
Theory of Computation asks you to classify languages, construct automata, and reason about decidability. The exam rewards knowing exactly which closure property or pumping lemma applies, and which machine model corresponds to which language class.
309 words, about 2 min08Compiler Design
Compiler Design tests the pipeline from source text to machine code, with heavy emphasis on parsing and a lighter touch on runtime organisation and optimisation. Questions are typically: build a FIRST/FOLLOW set, identify a conflict class, or count entries in a parsing table.
316 words, about 2 min09Operating System
The Operating System section covers process management, synchronisation, deadlock, memory management and file/disk subsystems. Questions are numerical (scheduling averages, page faults, effective access time) or conceptual (which condition is violated, which algorithm guarantees what).
301 words, about 2 min10Databases
Databases asks about the relational model, SQL, normalisation and transactions. Expect one question on relational algebra or SQL semantics, one on functional dependencies and normal forms, and one on serializability or concurrency control.
319 words, about 2 min11Computer Networks
Computer Networks covers layered protocols, error and flow control, addressing and routing, and transport behaviour. GATE questions are usually numerical - utilisation, subnetting, delay - or conceptual about which layer or protocol does what.
