Hello Srijit

The new NEST 2021 Exam pattern is as follows

1. There will be negative marking of 1/4 marks.
2. There will be no negative marking for leaving a question.
3. There are two section categories, section-1 carries 50 Marks, section-2 to 4 carries 50 Marks.
4. Yoh have to attempt all the sections.

I hope it helps.

Best of luck
