The cutoff varies every year, It depends on the category wise, home state/ Othere state & branches wise also so the exact prediction would be tough. In order to get admission in NIT Trichy try to score more than 250 marks, NIT Allahabad more than 220 marks, MNIT Jaipur more than 200 marks & NIT Hamirpur around 190 marks as a general category for the top branches.
