Hello Anubhav,

Congratulations on your GATE marks first of all! 

Since you haven't specified your GATE paper and score so let's consider things in general.

As you are a general candidate getting into NITs with these marks seems difficult. You may try for newer NITs and wait till the last rounds of counseling through CCMT. 

You can even apply for good state government colleges with these marks. They will have their own process of admission through GATE scores. 

You can refer to the following link for more information

Hope it helps!

If you have any more queries, you can revert back.

All the Best!

Please mention your gate score and branch?
