Guna,

You can only give gate exam once you have passed your final year of B.Tech i.e. the fouth year.

So, as of now I would advice you to keep preparing for the exam as it is one of the toughest around and improve on your strong points. 

I hope that you have already started preparing for the exam. Make your basic concepts clear and you can also follow thee given link to check the eligibility criteria of gate exam,2019 which was conducted by IIT Madras on February 2,3,9 and 10 in online mode-

All the best !!!
