Hi Aspirant,
It is a bit difficult to predict anything regarding cutoff for NISER and admission to it unless and until the marks for NEST 2021 are declared because there are a lot of factors on which the cutoff of each year depends number of applicants, total number of seats, etc. However looking at the previous year trends, the minimum admissible percentile or we can say the overall cutoff of 95% is advisable for general category students.

Hope this helps.
Good luck!!
