Yes, this year IIT Madras has revised the GATE syllabus 2027 for almost all subjects. Many topics and chapters have been simplified. Some chapters and topics have been removed. 

• For CSE, major changes in syllabus have been made in COA, Digital Logic, and Computer Network
• For ECE, 90% of the syllabus remains the same. Few changes are made in the engineering mathematics, signals and systems, etc. 

Candidates are advised to go through the syllabus/compare it carefully before preparing.

GATE exam pattern for CS, EC, EE, and ME comprises general aptitude section (GA) carries 15 marks, while the subject-based questions carries 85 marks, out of which engineering mathematics section consists of 13 marks. 

The GATE paper code for metallurgical engineering is MT. The eligible two-paper combination for metallurgical engineering is Engineering Sciences (XE). Candidates who want to opt for the MT paper must check the paper code carefully before applying. To apply for secondary paper, candidate must select from the drop-down menu available in the application form. 

Yes, candidates can change their subject/paper during the form correction process. The GATE 2027 application form correction facility will be available from October 14 to 21, 2026.
