Hello Aspirant,

The GATE 2019 qualifying cut off for Civil Engineering is 28.2 for General category.Only if you have qualified GATE exam you become eligible for M.Tech admission in IIT's and NIT's through GATE score.Also certain top ranked private and govt institutes admit only GATE cleared students for MTech.Pursuing Mtech in a reputed college is very important.In your case you have other options.Even if you have not cleared GATE, there are opportunities for you to do MTech.Certain private colleges only consider your UG CGPA and they conduct their own entrance exams.Also you can try for various state level entrance exams and get into a top ranking college.

Hope this helps.

All the best!!!
