full details about JRF through GATE 2021exam ?what are the qualifications needed?what is the salary package?how the work is to be?what rank should I get in gate 2021?

Manidipa Kundu Student Expert 26th May, 2020


mainly jrf recruitment is done by ugc net score, however institute like iit kharagpur, iit kanpur has lots of research fellow recruitment comes for students who are recently pass course , have interest for research in new technologies, interested to do phd in future ,should apply for jrf positions. however there is no specific number of recruitment do not comes every year, it depends on the projects and funding for hiring of jrf, however by getting good score in gate you may go for course and may apply for psus job.


my gate score is 260 ...and marks 24.62 which college i get Mtech seat caste

Manidipa Kundu Student Expert 25th May, 2020


see you did not mention which branch you belongs to, however at this score you have less chances for top nits and other tier 1 institute in india, I suggest you to try for some other mtech entrance test like vitmee, bits hd, manipal university entrance test etc.

I am belongs to civil engineering branch I got 249 gate score will get a seat in jntuh or ou

Manidipa Kundu Student Expert 25th May, 2020


see at this score you have less chances for jntuh or osmaia university if you opt for mtech in structural engineering related course and it goes for any of the category you belongs to, I suggest you to try some other mtech entrance exams like vitmee, bitshd.

will dual degree in IITS come for the GATE 2020 score 421 in ECE branch for an OC student

Sharon K Rose Student Expert 24th May, 2020


Candidates getting admission in dual degree through JEE Advanced need not to appear in GATE.And the cut off will not be the same for dual degree through JEE Advanced and through GATE.Considering previous year cut off trends it is difficult to get seat in IITs with such score.You need to score at least 600 or above to have decent chances of getting seat in a IIT.

My GATE score is 334 in Civil Engineering belonging to OBC category. Is there any chance for me to get admission in NIT?

Priyaanka Sarkar Student Expert 23rd May, 2020

To be honest with you, for a score of 334, a seat in Civil Engineering is going to be tad difficult b ased on previous years' data. Having said that this is based on 2019 data and cut offs change every year depending on various factors. Please use our GATE College predictor for possible chances:
