Dear Student,

Yes, you can take admission to M.Tech CSE through qualifying for the GATE CSE exam.

But, we will advise you to pursue your M.Tech with Civil Engineering as you studied every single thing of civil and lastly changing your domain can cause you to start from the bottom. Also, M.Tech is very much related to what you studied in B.Tech, so it will be harder to cope up with everything.
