hi,

see even if you get a non zero gate score, you are not qualified in gate exam, gate mechanical engineering cutoff for obc-ncl is 29.7 , since your score is lower, you did not qualify for gate exam this year. in sastra university gate score is not mandatory to have to become eligible for m.tech admission. you may apply as well in different streams based on your academic qualification, however gate qualified candidates would be given stipends as 12,400 per month.

There is various others exams like bits hd, ts pgecet, ap pgecet like exams are available for m.tech admission, non gate students are eligible to apply.

hope it would help.
