Hi Puneeth Royal,

Yes, You can attempt for both Gre and Gate but Don't waste your time in preparing for both exams and Just Stick to one of the exam and prepare well and if you want to do MS then give Gre exam and if you Want to do M.tech  then give Gate exam then get into top IIT's/NIT's

I would suggest you to give the GRE exam and go for MS.

Inbox me if you have any queries regarding Study abroad.
