Hi Vismaya,

First of all congratulations on your attempt in NEST irrespective of marks you got. Last year(2018)  qualifying cut off in NEST for the general category is 90. But to get a seat in NISER cut off for general candidate is 83 and for CBS is just 23. This year cut offs may or may not be the same. As the com[petition is increasing day by day it is quite difficult to estimate.

All the best.

Thank you.
