Hello aspirant,

I hope that you are doing absolutely great.

With reference to your above mentioned query, I would like to tell you that to get admission in various  M.tech courses, giving GATE Exam is sufficient to get into any of the IIT ( Indian Institute Of Technology)  colleges in India.

Further, if you don't get qualified for GATE Exam, then you can apply individually for some of private colleges for Mtech Biotechnology.

You cannot apply for any of teh individual IIT's. The admission of Mtech Biotechnology in any IIT's can only be done through GATE exam only.

Further, to know more about GATE examination, you can follow the below mentioned link :

I hope that this will help.
