Hello! Hope you are doing good

The cutoff depends on various factors such as the total number of students appearing for the exam and the difficulty level of the paper.

If the paper was easy, then a score of 48 has slight chances of getting into NITs. You can apply to colleges under home state quota.

If the paper was quite tough then with a score of 48 you can expect interview calls from IITs and direct admission to NITs.

All the best
