Hello Satyajit,

The cutoff depends on factors like number of applicants, number of seats available,minimum marks secured,difficulty level of the exam etc. So based on previous cutoffs when you see,150 is the cutoff needed for SC category to get admission in NISER BHubaneswar. Hence for your score chances are pretty low in NISER but you can go for CEBS ,Mumbai.
