Predict NowThe GATE 2025 syllabus for Mechanical Engineering (ME) has been released by IIT Roorkee, with no changes made from previous years. The syllabus is divided into four main sections, i.e., Engineering Mathematics, Applied Mechanics & Design, Fluid Mechanics & Thermal Sciences, and Materials, Manufacturing & Industrial Engineering. The GATE Mechanical Engineering exam consists of 65 questions, totaling 100 marks. Out of these, 10 questions are based on General Aptitude, and the remaining 55 questions cover Engineering Mathematics and core mechanical engineering topics. General Aptitude is common across all papers and accounts for 15 marks, while the remaining 85 marks are based on the GATE ME syllabus. The GATE 2025 syllabus for Mechanical Engineering includes topics from three main areas: General Aptitude, Engineering Mathematics, and Core Discipline. The detailed GATE syllabus 2025 along with key topics weightage etc. has been mentioned on this page.
