What is new in GATE 2027: a new paper, new sectional codes, and a revised syllabus

The GATE 2027 cycle

IIT Madras organises GATE 2027: 30 papers, a new Robotics and Automation paper, TF folded into XE as XE9, new XE/XH/XL codes, and a revised syllabus.

Everything structurally new in GATE 2027 is printed on a single page of the official Information Brochure. IIT Madras is the organising institute, and the official website is https://gate2027.iitm.ac.in. There are 30 test papers, all conducted as Computer Based Tests, all in English. Four items on that highlights page are new for 2027. Robotics and Automation (RA) is a new test paper. Textile Engineering and Fibre Science (TF) is no longer a standalone paper: it becomes a section of the XE sectional paper, XE9. The paper codes for the three sectional papers — XE, XH and XL — have changed. And the brochure states that the syllabus of GATE 2027 test papers has been revised and advises candidates to check it, which is what the second half of this post is about.

TF is still examinable, inside XE

Textile Engineering and Fibre Science is still examinable. The brochure's wording is that the TF paper “will be a part of XE sectional paper (i.e., XE9: Textile Engineering & Fibre Science) from GATE 2027”. Its syllabus is printed in the brochure's own syllabus appendix under XE9, beginning with Section XE9.1, Textile Fibres. What changed is where it sits: a candidate who would previously have applied for TF now applies for XE, in which applicants select at most two of the sections XE1 to XE9 during the exam, alongside the common section XE0.

The new paper: Robotics and Automation (RA)

Apart from the General Aptitude section, the RA test paper consists of two parts: Part A, carrying 60 marks, and Part B, carrying 25 marks. Part A is common to all candidates. Part B contains Part B1 (Electrical) and Part B2 (Mechanical), and the brochure says the choice between them can be made during the examination — not locked in at application time, as it is for the Geology and Geophysics paper. Part A is 39 questions: 18 carrying one mark each and 21 carrying two marks each. Part B1 and Part B2 are 16 questions each: 7 carrying one mark and 9 carrying two marks. With General Aptitude at 15 marks, the paper totals 100.

Three details about RA that are easy to miss

  • Section-wise score and ranking will not be provided for RA. The brochure gives that facility to the Geology and Geophysics (GG) and Humanities and Social Sciences (XH) papers, and names Architecture and Planning (AR), Robotics & Automation (RA) and Geomatics Engineering (GE) among the papers that do not get it.
  • RA is not in the list of papers where 13 of the 85 subject marks are reserved for Engineering Mathematics. It sits in the other group, where the 85 subject marks are undivided. Engineering Mathematics does still appear inside RA, as Section A.1 of the RA syllabus printed in the brochure.
  • RA can be taken as a second paper. Table 4 lists RA's allowed partner papers as EE, ME, DA, CS, EC and IN, and each of those six papers lists RA in return. The brochure marks that table tentative and subject to change.

Both the GATE 2026 code and the GATE 2027 code for every section are printed in that table; the section names and mark values above are the brochure's own. The per-section names behind each range — for example XE1 Fluid Mechanics or XL1 Biochemistry — are listed in the same table.

The line that matters most: the syllabus has been revised

The highlights page says the syllabus of GATE 2027 test papers has been revised and advises candidates to check it. It does not say which papers changed, or how much. So we checked. For each of the seven papers IAE teaches, we compared the official GATE 2026 syllabus PDF, published by IIT Guwahati, with the official GATE 2027 syllabus PDF, published by IIT Madras — section by section and item by item, with a script, and then adjudicated every difference by hand against both documents. Two of the seven papers turned out to have no listing change at all.

Source: Each row compares that paper's official GATE 2026 syllabus PDF (organising institute IIT Guwahati) with its official GATE 2027 syllabus PDF (IIT Madras), both read on 15 September 2026; the md5 of every PDF is recorded alongside the comparison. A row naming a comparison page links to a curated, script-checked document in which every entry quotes both PDFs. A row saying “nothing to report” means the comparison found no listing difference to adjudicate. The index of all five comparisons is at /resources/gate-2027-syllabus-changes.

Which papers changed shape, and which moved most

Two of the five changed papers changed shape, not only content. Civil Engineering gains an eighth section, Construction Materials and Management. The 2026 PDF carried that material as a block inside Section 2, Structural Engineering; in 2027 it is a section in its own right, and items such as PERT and CPM sit inside it. Biotechnology goes the other way: the 2026 section Bioprocess Engineering and Process Biotechnology has no counterpart in the 2027 PDF, so 2027 prints six sections where 2026 printed seven, and the Bioreaction Engineering list is printed inside Section 4, Fundamentals of Biological Engineering. The other three changed their listings without changing shape. Instrumentation moved most: all ten of its sections newly list something. Computer Science moved across the fewest sections — three of its ten — but eleven of that paper's twenty-one adjudicated entries fall in a single section, Computer Networks. The section-by-section detail for each of these lives on that paper's comparison page, where every entry quotes both PDFs.

What “not listed by name” means, and what it does not

Where the comparison says an item is not listed by name in 2027, that is a statement about the printed syllabus and nothing more: the 2027 PDF does not print that item. It is not a statement about what the examination may ask. An organising institute publishes a syllabus, which is a list of what is included, not a list of exclusions. Where an item instead moved between sections, or kept its place but gained or lost a qualifier, the comparison says exactly that, in those words.

What to do with this

Download the official 2027 PDF for your paper, free and un-gated, from our syllabus page, and read it against the comparison for your paper if one exists. If you sit EE or DA, there is nothing to re-plan: your 2027 listing is the same as your 2026 listing. If you sit CE, BT, IN, EC or CS, read your comparison page before you rebuild a study plan around a 2026 syllabus. Registration dates, the application fee, eligibility and how long a GATE score stays valid are not covered here — they are on our GATE 2027 application checklist, which is built the same way, from the same brochure.

Common questions

What is new in GATE 2027?+
IIT Madras is the organising institute. The brochure's highlights page lists 30 test papers, all Computer Based Tests and all in English; a new test paper on Robotics & Automation (RA); Textile Engineering & Fibre Science (TF) becoming part of the XE sectional paper as XE9; changed paper codes for the sectional papers XE, XH and XL; and a revised syllabus that candidates are advised to check.
Is Textile Engineering and Fibre Science (TF) still a GATE paper in 2027?+
It is no longer a standalone paper. The brochure says the TF paper will be a part of the XE sectional paper as XE9: Textile Engineering & Fibre Science, from GATE 2027, and prints its syllabus under XE9. A candidate takes XE and selects at most two of the sections XE1 to XE9 during the exam, alongside the common section XE0.
How is the GATE 2027 Robotics and Automation (RA) paper structured?+
Apart from General Aptitude, which carries 15 marks, RA has Part A (60 marks, common to all candidates, 39 questions) and Part B (25 marks, 16 questions), where Part B is either B1 (Electrical) or B2 (Mechanical), chosen during the examination. The paper totals 100 marks. Section-wise score and ranking are not provided for RA.
Have the XE, XH and XL paper codes changed for GATE 2027?+
Yes. The brochure prints both years' codes side by side. The common sections become XE0 (Engineering Mathematics, 15 marks), XH0 (Reasoning and Comprehension, 25 marks) and XL0 (Chemistry, 25 marks), where 2026 used XE-A, XH-B1 and XL-P. The optional sections become XE1 to XE9, XH1 to XH6 and XL1 to XL5, where 2026 used XE-B to XE-I, XH-C1 to XH-C6 and XL-Q to XL-U.
Which GATE 2027 syllabi actually changed?+
Of the seven papers IAE teaches, five changed: CE, BT, IN, EC and CS. EE and DA have no listing change — EE's only difference between the two PDFs is the spelling of Butterworth, and DA's 2027 PDF lists the same items as 2026, only under numbered sections. Each changed paper has its own comparison page, indexed at /resources/gate-2027-syllabus-changes.
Does a topic missing from the GATE 2027 syllabus PDF mean it is out of the exam?+
No, and we do not describe it that way. Our comparisons say an item is “not listed by name” in 2027, which means only that the 2027 PDF does not print it. A syllabus is a list of what is included, not a list of exclusions, and the brochure's own wording is simply that the syllabus has been revised.
