NEW DELHI: The Graduate Aptitude Test in Engineering (GATE) 2025 syllabus for the computer science and information technology (CS) paper has 10 sections. The Indian Institute of Technology (IIT) Roorkee released the syllabus and paper pattern for GATE 2025 on the official website, gate2025.iitr.ac.in.

GATE registration 2025 will commence from August 24. The exam will be conducted on February 1, 2, 15, and 16 for 30 test papers. GATE 2025 scores will be used by the IITs and other participating institutions for admitting students to their MTech programmes.
