Hey,

The minimum eligibility required to sit for NEST exam is that

- the students should have passed their 10+2 from a science stream.

-minimum of 60% marks in your 12 th for general category and 55% marks for reserved category students.

Below is the link you can refer to for more help,

Based on the above criteria I believe you are eligible for admission in NISER if you get good marks in Nest.

All the very best.

Thank you.
