Hello , I see that you have got quite a good rank in JEE mains paper two that is for barch. Having 1504 rank in OBC category. It is good but it is not enough to get you a seat in nit Calicut.

Your rank is way too much than required rank in nit Calicut. 

I suggest you to visit josaa website and see previous year closing rank it will give you a pretty idea about which college will you get.

Thank you.
