About GATE 2021 EXAMS
The GATE (Graduate Aptitude Test in Engineering) is a national level online examination conducted for Masters in Technology (MTech), Master of Engineering (ME), and direct Ph.D. entry to the Indian Institutes of Technology (IITs), National Institutes of Technology (NITs), IISc Bangalore, Indian Institutes of Information Technology (IIITs) and other institutes across India.
Several Public Sector Undertakings (PSUs) including, BHEL, DRDO, IOCL, NTPC, and ONGC, also use GATE score in their recruitment process. On behalf of the National Coordination Board (NCB - GATE), MHRD, Government of India GATE exam is conducted jointly by IIT Bombay, IIT Delhi, IIT Madras, IIT Roorkee, IIT Guwahati, IIT Kanpur, IIT Kharagpur, and IISc Bangalore. The GATE exam is held to test the understanding of aspirants at the undergraduate level of Technology/Architecture and post-graduate level of the Sciences.
Candidates can choose two subjects/papers in combinations. Candidates were previously only eligible to apply for one subject/paper.
