Hi Jaya!
You can pursue B.Sc in catering from this college but you have to start with B.Sc in catering from the 1st year itself.

Yes, there is a big chance for you to get into NIT. Since you are from OBC category there is a big opportunity for you. This rank is more than enough for admission in NIT, Calicut.
