Gate 2021 Physics Syllabus PH : GATE 2021 information brochure at gate.iitb.ac.in

 

Gate 2021 Physics Syllabus PH : https://gate.iitb.ac.in : Graduate Aptitude Test in Engineering (GATE) is a national examination, conducted jointly by Indian Institute of Science (IISc) Bangalore and seven Indian Institutes of Technology (IITs) at Bombay, Delhi, Guwahati, Kanpur, Kharagpur, Madras and Roorkee on behalf of National Coordination Board (NCB)-GATE, Department of Higher Education, Ministry of Education (MoE), Government of India. GATE examination is a Computer Based Test (CBT).

GATE 2021 will be conducted for 27 Subjects (also referred to as “papers”).

GATE 2021 examination will be conducted over six days and twelve sessions on Friday 5th, Saturday 6th, Sunday 7th, Friday 12th, Saturday 13th and Sunday 14th of February 2021.

Note:

Candidates opting to appear in TWO subject papers must have a primary choice of paper, which will be their default choice and second choice of paper, which has to be chosen from the allowed combinations. Combinations other than the listed ones are NOT allowed. Under unforeseen circumstances, GATE 2021 committee has the rights to remove certain combinations at a later date. In such case, the fee paid towards the second paper will be refunded to the candidates. Also note that the examination centre for candidate to appear for the second paper may be different (but in same city) from that for the first paper due to the infrastructure and scheduling constraints. GATE committee is NOT liable for any legal obligations related to this issue.
