Hii aspirant ,

Coming to your question I would like to tell you that you had chances to get into these institutes s your OBC rank is in the range of the previous year rank cutoff for the nit Calicut and the nit Allahabad ,the 576 and the 641 was the previous year cutoff , and hope this year the trends follows the same , just be relaxed you will definately get one out of the two .

Hope this helps you ,

Good luck.
