GATE 2025 Syllabus
The Graduate Aptitude Test in Engineering (GATE) is an exam that helps you in getting admission for Masters in premium institutes like IITs, NITs, etc., and also helps in getting jobs at PSUs. The GATE syllabus helps you understand where the questions will come from in the paper. In this article, we are going to discuss the GATE Syllabus of all streams for the GATE Exam.
GATE Syllabus gives you ideas about where questions will come in the exam that ultimately help you in gaining a good GATE Score. There are several streams for which the GATE Exam is conducted. But from last year, GATE 2024, GATE is going to be conducted in the Data Science and Artificial Intelligence (DA) Stream. IIT Roorkee is going to conduct the exam this year and will release the Official Notification for GATE 2025.
