GATE CS - Computer Science and Information Technology, paper code CS, which most candidates call GATE CSE - is one of the six GATE papers Myndaq prepares candidates for (the Myndaq GATE CS course), and this guide is its dedicated map: where the official 2027 syllabus PDF is and how to use it, the ten sections it contains, the paper frame, what is and is not published about section weightage, and the strategy decisions that are specific to this paper rather than to GATE in general.
Dates, pattern and syllabus links in this guide were checked against the official GATE 2027 site on 3 September 2026; the article was revised on 6 September 2026 without changing any date.
The GATE cycle you are preparing for
GATE runs on the same annual shape every cycle, and the shape is more useful than a memorised date: the application portal opens around the start of September, regular registration closes in late September without a late fee, and an extended window stays open about a week longer with one. Registration through DigiLocker is mandatory for Indian nationals. The examinations are held across three weekends in February, your exam city is notified in early January, and results follow in March. Two consequences follow. The only unforgiving deadline sits in the first month of the cycle, roughly five months before you sit the paper - so the application is settled long before the real preparation ends. And the organizing institute rotates between the IITs and IISc from cycle to cycle, which is why the official site's address changes each year. Test-paper syllabi are also revised between cycles, so download the official syllabus PDF for your own cycle rather than reusing an older year's copy. Confirm the exact dates on the official important-dates page linked in the sources below, and see how the GATE schedule is built for the full sequence.
The CS paper in the GATE frame
The paper itself follows the standard GATE frame: 65 questions, 100 marks, 3 hours, computer-based, with General Aptitude contributing 10 questions for 15 marks and the subject component 55 questions for 85 marks across MCQ, MSQ and NAT formats. The exam pattern and negative-marking maths are decoded in their own guide, and because high-volume papers run multiple sessions, your marks pass through normalization before they become a GATE score. The branch-agnostic preparation system - the 6-month plan, the mock cadence, the error ledger - lives in the GATE 2027 preparation guide; this page adds what is specific to this paper.
Where the official GATE CSE syllabus PDF is, and how to use it
The only authoritative syllabus is the PDF that IIT Madras publishes on the GATE 2027 site, at gate2027.iitm.ac.in under the exam papers and syllabus page; the direct link is in the sources at the end of this article. Coaching-site copies are usually accurate but are sometimes last year's file with a new heading, and the GATE 2027 notice states that test-paper syllabi have been revised, so download the official file and work from it.
Use it as a checklist rather than a reading list. Print or copy the ten section headings with every topic phrase under each, and mark each phrase with one of three states as you go: not started, covered from notes, and tested under time. A phrase counts as tested only when you have done previous-year questions on it against the clock. This turns a two-page PDF into the tracking document for the whole preparation and stops the common error of counting a topic as done because a lecture on it was watched.
The official syllabus, section by section
The summaries below follow the official GATE 2027 CS syllabus PDF. They are orientation, not substitutes - the PDF's topic phrases are the coverage checklist.
Engineering Mathematics
Discrete mathematics leads this section - propositional logic, sets, relations, combinatorics, graphs - alongside linear algebra, calculus and probability. Discrete maths behaves like a core CS subject here, not a formality: it feeds directly into Theory of Computation and Algorithms.
Digital Logic
Boolean algebra and minimization, combinational and sequential circuits, and number representations including computer arithmetic in fixed and floating point.
Computer Organization and Architecture
Instruction sets and addressing, ALU and data-path, pipelining and hazards, the memory hierarchy - cache, main memory, secondary storage - and I/O interfacing. Cache and pipelining numericals are classic NAT territory.
Programming and Data Structures
Programming in C with recursion, plus arrays, stacks, queues, linked lists, trees, BSTs, heaps and graphs. Code-tracing accuracy under time pressure is what the paper actually tests.
Algorithms
Searching, sorting and hashing, asymptotic analysis, and the design canon - greedy, dynamic programming, divide-and-conquer - with graph traversals, shortest paths and spanning trees.
Theory of Computation
Regular expressions and finite automata, context-free grammars and pushdown automata, pumping lemmas, Turing machines, and decidability.
Compiler Design
Lexical analysis, parsing, syntax-directed translation, runtime environments, intermediate code and local optimisation basics.
Operating System
System calls, processes and threads, concurrency and synchronization, deadlock, CPU scheduling, memory management and virtual memory, and file systems.
Databases
ER-model, relational algebra and calculus, SQL, integrity constraints and normal forms, file organization and indexing, and transactions with concurrency control.
Computer Networks
The layering model, switching, IPv4 addressing and routing, transport protocols - flow and congestion control in TCP and UDP - and application protocols like DNS, SMTP and HTTP.
What is published about weightage, and what is not
The pattern page fixes only two numbers: General Aptitude is 15 marks and the CS subject component is 85 marks, across 65 questions in three hours. GATE does not publish a marks split across the ten syllabus sections, and the split varies from year to year and between sessions of the same year. Any "section-wise weightage" table you see online is somebody's count of past papers, not an official allocation, and a table that gives one number per section without a year attached is not verifiable.
The verifiable way to judge weight is to count the marks per section in the last several official CS papers yourself; the papers are published by each year's organising institute. Doing that count is a good early exercise because it also shows you how questions combine sections - a single 2-mark question on cache performance is at once Computer Organization and Engineering Mathematics - which is why preparing sections in isolation under-prepares you for the paper. Whatever the count shows, the syllabus is the commitment: every section can carry 1- and 2-mark MCQ, MSQ and NAT questions, and the negative-marking rules apply only to MCQs.
Strategy that is specific to CS
CS is consistently among the highest-registration GATE papers, which has two practical consequences. First, normalization across multiple sessions is almost guaranteed, so judge yourself on percentile-style consistency in mocks, not raw marks. Second, the qualifying and admission cutoffs sit close together at the top - the discriminating questions are usually multi-concept: a NAT that chains cache arithmetic with pipeline stalls, an MSQ that tests four independent truths about TCP. Train for combinations, not just topics.
A CS-specific sequencing that works: run Discrete Mathematics and Programming/Data Structures first and in parallel - together they unlock Algorithms, TOC and Compiler Design with far less friction. Keep COA, OS, DBMS and Networks as a second wave, where steady PYQ volume converts directly into marks. If you are also weighing the Data Science and AI paper, the CS vs DA comparison breaks the decision down by syllabus overlap and goal.
Quick answers
Is the GATE CS syllabus the same as last year? The official notice for GATE 2027 states that test-paper syllabi have been revised. Work from the official CS PDF for GATE 2027 linked below and treat any older syllabus copy as unverified.
How much of the CS paper is Engineering Mathematics? CS includes a separately identified Engineering Mathematics share inside the 85-mark subject component, with discrete mathematics as its distinctive core. The official pattern page and syllabus PDF are the authority on structure.
Is GATE CS the same as GATE CSE? Yes. The official paper is Computer Science and Information Technology with the paper code CS; "CSE" is the everyday name candidates and coaching sites use. There is one paper and one syllabus.
Where do I download the GATE CSE 2027 syllabus PDF? From the official GATE 2027 site run by IIT Madras; the direct link to the CS syllabus PDF is in the sources below. Treat any other copy as unverified until you have compared it with the official file.
Does GATE publish section-wise weightage for CS? No. Only the General Aptitude 15 marks and subject 85 marks split is official. Section weights seen online are counts of past papers and change every year.
