The Indian Institute of Science (IISc) and seven Indian Institutes of Technology (IITs at Bombay, Delhi, Guwahati, Kanpur, Kharagpur, Madras and Roorkee) jointly administer the conduct of GATE. The operations related to GATE in each of the 8 zones are managed by a zonal GATE Office at the IITs or IISc. The Organizing Institute (OI) is responsible for the end-to-end process and coordination amongst the administering Institutes.
Graduate Aptitude Test in Engineering (GATE) is an examination that primarily tests the comprehensive understanding of the candidates in various undergraduate subjects in Engineering/Technology/Architecture and postgraduate level subjects in Science. The GATE score of a candidate reflects a relative performance level in a subject in the examination across several years. The score is used for admissions to post-graduate programs (e.g., M.E./MTech/ Direct Ph.D.) in centrally funded Indian Institutes of higher education (i.e., Institutes which are provided with financial assistance by MHRD and other Government agencies).
The score is also used by some Public and Private Sector Undertakings for employment processes in India. Direct recruitment to Group ‘A’ level posts i.e., Senior Field Officer (SFO Tele), Senior Research Officer (SRO) (Crypto) and SRO (S&T) in Cabinet Secretariat is now being done based on GATE scores.
This year GATE 2022 examination shall be held in Bangladesh, Ethiopia, Nepal, Singapore, Sri Lanka and United Arab Emirates for admissions of candidates from these nationalities in IITs and IISc.v
Type of Questions in GATE EXAM
The GATE examination shall be of 3 hours duration with a maximum of 100 marks. The question paper for GATE 2022 will consist of questions which are of (1) multiple-choice type (2) numerical answer type (3) Multiple Selection Type. For multiple choice type questions, candidates must choose the answer from the given choices.
For numerical answer type questions, candidates have to enter a number as the answer using a virtual keypad. For Multiple Select Questions, more than one option can be correct and to secure full marks for that question, student has to select all the correct options.
