Graduate Aptitude Test in Engineering (GATE) is the entrance test conducted jointly by the seven Indian Institutes of Technology (at Kharagpur, Guwahati, Kanpur, Madras, Bombay, Delhi, and Roorkee), and Indian Institute of Science (IISc), Bangalore. Universities across India use the GATE test scores to shortlisting candidates for admissions to their Masters and PhD courses in the engineering and technology stream. The PSU’s like Coal India, Airport Authority, SAIL, NLC, Power Grid, NPCIL etc also uses these scores to hire for the graduate positions. The next GATE is scheduled for February 2022, and IIT Kharagpur will be the exam conducting organization. To prepare for the GATE Mechanical Engineering stream, aspirants can now check the GATE 2022 syllabus and exam pattern given below.
